The study of 'Chail Series', 'Jaunsar Series' and 'Simla Slates' in the Simla Himalaya has brought out the incongruities in the present lithostratigraphy of these formations. The Simla group, divisible into four formations, is the revised classification proposed. The Basantpur, with shale, siltstone and abundant limestone interbeds, is at the bottom of the Simla group sequence, and in the ascending order, succeeded by the Kunihar with shale and stromatolitic limestone, the Chhaosa containing flysch sediments and the Sanjauli with conglomerate and grit facies. The Simla group represents a typical geosynclinal cycle of sedimentation deposited over the Shali, Sundernagar and Mandi-Darla volcanic rocks.- The Occurrence of Rocks of Kakara (Paleocene) Affinity in the Bakhalag-Bughar Belt, Himachal Pradesh

A complex association of limestones, quartzites, slates and volcanic rocks and ashes exposed In the Garhwal Himalaya was first called as 'Jaunsar System' by Oldham. Pilgrim and West adopted the name 'Jaunsar' for their Jagas Series c - a selective quartzite-slate association, and Auden variously considered his Mandhali-Chandpur-Nagthat association of diverse lithology, and the Nagth Nagthat Series of quartzite-phyllite association as 'Jaunsar'. Later workers either adopted the classification of Pilgrim and West, or of Auden, or reclassified the Chandpur-Nagthat to include crystallines and metamorphics, without much regard to the larger stratigraphic Implications of the same. This has resulted In great confusion In the stratigraphy of the Himalayas leading to conjectural correlations of formations and hypothetical interpretation of structures.
The present study has shown that the 'Jaunsars' are variously part of the Simla group of Srikantia and Sharma or are part of the sequence of the Mandhali-Chandpur-Nagthat. The recent attempt to include rock types referable to the Jutogh as part of the Chandpur-Nagthat is mainly due to the non-recognition of a thrust contact between these two which is obscured due to post-tectonic metamorphism and deformation, and hence is not an acceptable proposition.
It is now proposed to redefine the term 'Jaunsar' and to strictly restrict it to the restored sequence of Mandhali, Chandpur and Nagthat formations. The Jaunsar group as adopted now represents a typical geosynclinal type of sediments deposited on the eroded surface of the Deoban belt. It is characterised by the association of the Bhowali volcanics and the acid intrusives of the Kharasali gneiss, and is typically eugeosynclinal. Structurally it occurs as a superficial nappe over the isopic zones of the Deoban-Simla group in the southern part of the Deoban belt.
The Jaunsar group, the Simla group and the Rampur formation are considered as contemporaneous formations in the present scheme of correlation of geosynclinal sediments In the Lesser HImalaya.

An association of quartzite, slate and basic volcanics forming the foundation of the Shali Group is designated as the Sundernagar Group. The base of this formation is not exposed and the entire edifice of the sequence, ranging from the Shali, Simla, Blaini, Infra-Krol, Krol, and the Tertiaries, is built upon this formation making it stratigraphically the deepest sediment in the Peninsular or the Lesser Himalaya.
As the history of the Sundernagar Group is closely linked with the events in the northern part of Peninsular India, a correlation is attempted with the Pre-Vindhyan groups like the Delhi, Bijawar and Gwalior. In the Lesser Himalaya, it has been found that most of the older Proterozoic carbonate belts like the Larji, Deoban, Tejam-Pithoragarh, Suparitar (Nawakot) and Baxa contain, at their base an association of quartzite, slate and volcanics. This proves the widespread extension of the Sundernagar rocks and the Mandi-Darla Volcanic episode in the Himalaya during the Delhi period.
From the present study it is postulated that the Pre-Delhi basement complex forms the basement for the entire sedimentary sequence in the Peninsular Himalaya.

Geochemical investigations on the Jaspa granites and Rohtang gneisses from Himachal Pradesh indicate that the Rohtang gneisses are the migmatlsed/granltised products of the pre-existing metasediments and the Jaspa granite is an intrusive granite. Field relationship suggests that the Jaspa granite is a post-tectonic intrusive while the migmatisation/granltisation of the gneisses appear to be pre-and syntectonic and might have continued into the post-tectonic period.- The Kainchwa Granitic Complex of the Jutogh Belt of the Chaur Mountain Area, Simla Himalaya

The Tandi Group of Lahaul area in the Himachal Higher Himalaya represents a sequence of essentially carbonate rocks. It is underlain by chlorite phyllite representing possibly metamorphosed lava flows and overlies Precambrian-Eocambrian Batal Formation of the Haimanta Group. The Tandi Group has yielded significant fossil assemblage indicating a Permian to Triassic and possibly Jurassic age. Structurally, the Tandi Group constitutes an overturned syncline with a southwest dipping axial plane. The overturned limb has thrust imbricates suggesting a direction of movement from sw to NE.
The Tandi Group represents a major Permo-Trias marine transgression from Kashmir in NW through Bhallesh and Chamba. It has no direct relationship with the Central Crystalline Gneiss which occupies stratigraphically the deepest position in the area and forms a geanticline separating the Spiti-Zanskar basin from the Kashmir-Bhallesh-Chamba- Tandi-basins.
The Tandi rocks suffered intense deformation together with the basement rocks due to its proximity to the main orographic axis. The Precambrian-Eocambrian basement rocks have vestiges of folds older than the Himalayan folds.

In the Central Ladakh Himalaya, the Ladakh Granitic Complex with Kharbu Group, the Indus Tectonic Zone and the Spiti-Zanskar and Kashmir Precambrian Phanerozoic belts constitute the chief geological units. The Ladakh Granitic Complex comprises a heterogeneous association of granitoids, gabbroids and basic rocks. The Spiti-Zanskar and Kashmir belts comprise Precambrian-Eocambrian crystallines and Late Palaeozoic-Mesozoic sediments.The Indus Tectonic Zone, a name adopted in preference to the Indus Suture Zone consists of two parallel and almost homotaxial sedimentary belts viz., the non-ophiolitic Indus Group in the north and the ophiolitic sedimentary volcanic belt of the Sangeluma Group in the south. The Indus Group unconformably overlies the Ladakh Granitic Complex, and the Sangeluma Group tectonically overlies the former. The Indus Group is divisible into the Skinding, the Kuksho, the Maklishun and the Karit Formations in the ascending order, and the Sangeluma into the Khalsi, the Dras Volcanic, the Nindam and the Shergol Formations with ophiolite association in all the formations excepting the Nindam.
The Indus Group cycle of sedimentation comprises, shallow diamictite, flyschoid, lagoonal and molassic stages, whereas the Sangeluma comprises the platform, submarine volcanic, flyschoid and unstable shelf type sedimentation.
Tectonically, the area can be divided into: Ladakh Granitic Complex-Indus Group autochthon, the Sangeluma parautochthon, the Kuling-Lilang schuppen belt, the parautochthon of Spiti-Zanskar and Kashmir Precambrian-Phaneroxoic belts and Shilakong ophiolite nappe.
The Indus Tectonic Zone was an original mega lineament which later became a site of opening of sea and sedimentation for the Indus and the Sangeluma. A sequence of stages of sea-floor spreading subduction and closing is envisaged.

The Shilakong ophiolite nappe occurs along the crest of the Zanskar Mountains in Ladakh, tectonically resting over the Mesozoic-Cenozoic sediments of the Spiti-Zanskar basin. It comprises two sub-nappe units. The lower Photang sub-nappe is made of pillow lava, basalt, volcanogenic sediments, purple chert and carbonate rocks with slivers of serpentinite. The Spong sub-nappe comprises mainly harzburgite, dunite and lherzolite in different stages of serpentinisation. The Shilakong ophiolite nappe is comparable with the Kiogar-Amlang La ophiolite nappe complex south of Kailas in South Tibet-North Kumaun region. These ophiolite nappes represent squeezed up material from the deep sea regime along the Inclus Tectonic Zone and are now obducted onto the continental zone as the highest allochthon in the Himalaya.- A Note on the Tectonic Framework and Geologic Set-Up of the Pangong-Chushul Sector, Ladakh Himalaya

The Pangong Tso-Spanggur Tso and the Shyok-Chushul-Dungti are the two tectonic zones in the area north of the Ladakh Range. The former zone has an association of metapelites, metacarbonates and metavolcanics in a graben type basin bounded by granitoids. The latter zone comprises Orbilina limestone, argillite, lava flows and grey-purple conglomerates in another graben type basin bounded on the NE by Pangong Granitoid and on the sw by the Ladakh Granitoid belts. These, along with the Indus Tectonic zone represent NW-SE trending parallel tectonic zones in the Trans-Himalayan Zone. The Pangong Tso-Spanggur Tso appear to be part of the larger Permian basin of Tibet. The Orbiloina limestone-volcanics-conglomerates or the Shyok-Chushul Tectonic Zone are comparable with the Sangeluma belt or the Indus Tectonic Zone. These are independent zones but comtemporaneous in development.- History of Paleozoic Salt Accumulation

The Jutogh klippe near simla is the highest allochthon in the Himachal Himalaya. Its base is defined by the Jutogh Thrust. Five mappable lithostratigraphic formations are recognised. These are variously represented, in the ascending order, by carbonaceous phyllite and schist of Panjerli Formation; quartzite unit of Manal Formation; phyllite, schist and quartzite of Bhotli Formation; quartzite unit of Khirki Formation and carbonaceous schist, crystalline limestone of Taradevi Formation.
S0 and S1 are the prominent planar surfaces with local development of S2 and S3. F1, F2 and F3 are the three generations of folds. F1 is in minor scale as appressed and reclined folds related to tectonic transport and F2 and F3 having formed after the emplacement of the thrust sheet. F2 is the most pervasive structure along NW-SE, folding the klippe into an open synform. F3 is a larger cross-fold along WSW-ENE and is responsible for culminations and depressions of F2 folds.
The direction of tectonic transport is from ENE to WSW and F2 folds indicate a compression along the same direction.

A critical study brings out that the 'Chail Series' broadly occurs in two tectonic positions - the 'Lower Chail allochthon' as a thrust sheet over the Shali and the' Upper Chail allochthon' as an infra-Jutogh thrust sheet. The revision mapping of the Simla area has brought out that the' Lower Chail allochthon' includes (i) a sedimentary unit occurring as a cover over the Shali and designated as the Basantpur Formation of the Simla Group and (ii) a regional nappe tectonically overlying the Shali-Simla Groups and designated as the Salkhala thrust sheet. The' Upper Chail allochthon' has been found to be part of the Jaunsar Group. Thus, the' Chail ' was never an entity and has lost its validity as a stratigraphic term. This naturally precludes its adoption even as a tectonic term.- Kuppalapalle Volcanics - A Distinct Upper Papaghni Volcanic Activity in the Cuddapah Basin

The Banasandra Komatiites occur within the Kibbanahalli arm of the Chitradurga supracrustal Belt in Karnataka. They apparently overlie the Bababudan Group and the Peninsular Gneiss and occur in two isolated exposures, (i) east of Birasandra, and (ii) near Kodihalli - Kunikenahalli. Ultramafic rock types include pillowed serpentinites, spinifex-textured komatiite, massive and schistose serpentinite and talc-tremolite-chlorite schist. Certain quartz-antigorite (birbirite ?), quartz-amphibole, and high-magnesian chlorite rocks are also closely associated with the ultramafics. The major element chemistry of the Banasandra komatiites compares with those of Barberton, S. Africa, Munro Township, Canada and of W. Australia. The exact relationship between these komatiites and the Bababudan volcanics is not clear for lack of continuous outcrops. Field evidences point to possible tectonic emplacement.- Trilobite and Other Trace Fossils from the Kunzam La Formation, Eastern Lahaul Valley, Himachal Himalaya

Trilobite locomotion trail Isopodichnus sp., swimming grazing trace Monomorphichnus sp. and resting trace Rusophycus didymus are recorded from the siltstone-shale-quartzarenite sequence of the Kunzam La Formation (Cambrian) from the eastern Lahaul Valley, Himachal Himalaya. Besides these, a ringed conical ichnocoenosis is also reported.
The trilobite traces belong to Cruziana 'facies' which is characteristic of stable infra-littoral to circa-littoral zones. The presence of Rusophycus suggests a rather low energy environment.

The Himalayan Orogen is characterised by a series of linear and parallel thrusts demarcating individual tectono-stratigraphic units. Two major tectogens, the Lesser Himalayan and the Tethyan, are recognised and these are separated by the Main Central Thrust (MCT). The MCT is the most fundamental of all thrusts in the Himalaya and represents the outermost tectonic transgression of the crystalline thrust nappes with or without Phanerozoic Tethyan cover over the Lesser Himalayan tectogen. The MCT can be recognised all along the Himalaya and is invariably characterised by retrogressive metamorphic characters and schuppen structures. It also comprises sub-nappes like the Salkhala and the Jutogh in the NW Himalaya.The Lesser Himalayan Tectogen has several structural belts demarcated by well-defined thrust planes and imbricate zones. The Himachal Himalaya has the maximum development of these structural belts.
Another important aspect of Lesser Himalayan tectogen is the extensive detachment of cover rocks along the planes of unconformity or even bedding.
Along the northern margin of the Tethys Himalayan tectogen, the thrust sheets generally have a NE-directed movement, whereas along the southern margin the thrust sheets have SW-directed movement. The highest allochthon in the Himalaya is represented by the Shilakong and Jungbwa ophiolite nappes.
The Indus Tectonic Zone borders the Himalaya along its northern margin and is represented by two structural belts viz. the Sangeluma and Indus belts.

The paper records the first occurrence of Orbicular rocks from the Closepet Granitoid belt near Hoskote, Tumkur district, Karnataka. The orbicules occur in a dioritic country rock enclosed within grey Closepet Granitoid. These are multishelled orbicules with shells of plagioclase and hornblende with a core of the same minerals. There are also proto-orbicules. The chemical analyses of orbicules fall in mafic tonalite field on K2O - CaO plots. Individual shells reflect a basic rock parentage. The orbicules are derived from a metabasic enclave due to granitic action by melting, diffusion and concretionary process in hydrous stage.Keywords

Situated along the left bank of the river Cauvery, Talakad represents a typical riverine sand dune. The point bar deposit along the left bank of the Cauvery is the main source of the sand. However, this stretch, in the upstream has a weir built some 400 years ago which diverted water from the Cauvery into the Madha vamantri canal, which resulted in the lowering of the level of water in the point bar deposit downstream thereby exposing its sand to monsoonic winds blowing from SW to NE towards Old Talkad. The settlements and also the NW to SE blowing cross wind in the valley acted as barriers for the sand laden monsoonic winds with the consequent development of sand dunes which on gradual migration buried temples and many old settlements.Keywords
