A study of the nature of the basal sediments of the Cuddapah System and their position in space with respect to the Archaeans has resulted in the understanding of the probable original extent of the Cuddapah sea in the south, and the uplift which the southern part of the basin might have experienced. It is suggested that the faults along the Archaean-Cuddapah boundary in the south and south-west, and some within the basin affecting the Lower Cuddapah rocks, are due to these gradual uplifts of the south-eastern part of the basin, which range in time from post-Lower Cuddapah to pre-Tertiary.
Evidences are adduced to show that the pattern of major river development in the southern part of the basin is not due to either transverse subsequent drainage, or progressive piracy or antecedence, but is due to superposition (or superimposition) on a structural plain of the Kurnools, about 3,000 feet above mean sea level, over the south-western part of the basin and gradual lowering of the rivers since Tertiary times. The effect on the rivers due to oscillations of sea level during the Pleistocene is also shown.

A study of the morphological features in and around the southern part of the Cuddapah Basin brought to light for the first time the existence of erosion surfaces in this area. Two methods were adopted in an attempt to arrive at quantitative data on these, namely (i) collection of data on summit heights (about 1800 in number) over an area of about 8000 sq. miles and (ii) construction of a large scale laboratory model covering an area of about 13500 sq. miles showing 30 north-south profiles taken from 60 one-inch toposheets. As erosion surfaces usually extend across different geological horizons, the study was made to cover both the southern part of the Cuddapah Basin and the Archaeans to the west and south of it.
On the basis of the above studies substantiated by field observations, it is concluded that there are two major erosion surfaces, one around 3000-2700 feet and the other around 2000-1600 feet above mean sea level in this area both having a gentle inclination due north and north-east. The erosion surfaces seem to have been arched along an east-west axis south of the basin. The two surfaces are correlated with two others already suggested in the former Mysore State. The age of the higher surface is considered to be post-Miocene.

In the Nellore and Guntur districts of Andhra Pradesh a series of detached hills composed of interbanded quartz-magnetite rocks, garnetiferous quartzites, pyroxene granulites, hypersthene-magnetitites and ferruginous schists extend for 33 miles from Konijedu in the south to Vemparala in the north. This paper mainly deals with the structure and petrography of the northernmost group of these rocks at Vemparala.
In this area the rocks have been metamorphosed and folded, whose axial plane trace only (FI) can be recognised. These have been folded again (FU) with eastward dipping axial planes trending NNW-SSE accompanied by gabbroic and granitic intrusions. The third folding (FIll), in the nature of a cross-fold, is along axes plunging NNE. There are many faults trending roughly N-S and E-W.
Mapping of the structure of a part of the eastern margin of the Cuddapah Basin between Cumbum and Markapur by the authors has revealed the presence of an earlier fold axis trending NW-SE and plunging due NW and a later cross-fold trending NNE-SSW and plunging due NNE. A study of the region from here eastwards to the Konijedu-Vemparala area, a distance of about 60 miles, has shown that the earlier fold axes (or axial plane traces) vary in trend, but the cross-fold axes show fairly consistent trend and plunge due NNE. It is therefore suggested that this region as a whole must have been affected by one and the same set of tectonic forces during its last stage of deformation.

In the Iron Ore Ranges of Bihar and Orissa, three erosion surfaces have been recognised around 3000-2700 feet, 2300-2000 feet and 1600-1400 feet above M.S.L., based on model studies in the laboratory, and the relative positions in the field of the residual deposits of laterites and lateritic iron and manganese ores. These have been correlated with those in the neighbouring areas in the southeastern Chota Nagpur and the Simlipal massif in Bihar and Orissa respectively. Based on the study of sedimentary record in the adjoining Bengal Basin, the tentative ages assigned to them from the top are Upper Jurassic to Lower Cretaceous, Upper Eocene and Upper Miocene.

It is now realised that the course of the river Cauvery in South India as observed is different from what it was during its inception during late Cretaceous or early Tertiary times. The upper part of the course over the Mysore plateau might have had only slight modifications both headward as well as laterally; but the lower part from Sivasamudram appears to be quite different.The vast flood plain of Palar, negligible flow even during flood times, the long and broad NE-SW trending dry valley from around Pennagaram in the south to Vaniyambadi in the north extending for about a distance of 65 miles in Tamil Nadu, southeast of Mysore plateau, require satisfactory explanation. It is suggested that the lower part of the Cauvery (Proto-Cauvery) flowed from Hogenakal, through the above valley on to the present course of the Palar river, and that the changes in the course of the rivers in this region were brought about during the Tertiary times, mainly aided by headwa(d erosion by tributaries along fracture zones and fault zones in the region.

A series of detached hills composed of quartz-magnetite rocks and diabases occur in the districts of Medak, Nizamabad, Adilabad and Karimnagar of Andhra Pradesh. The country rock is granitic gneiss and is cut across by a number of dykes. The structure of these rocks near Siddipet in Medak district has been studied in detail, and a number of traverses also made between Armur and Jagtial to the north in the districts of Nizamabad and Karimnagar to infer the probable overall structure of the region.
The quartz-magnetite rocks contain quartz and magnetite only and are devoid of ferro-magnesian minerals. The diabases in the Siddipet area are divided into two groups, one rich in hornblende and the other in pyroxene on the basis of petrographic study.
From a study of the outcrop pattern of the quartz-magnetite rocks and diabase bands in the Siddipet area, three traces of axial planes of folds (FI, FII, FIII) possibly related to three ages of folding are inferred. These rocks have been faulted along N-S and NE-SW directions. From the overall pattern of outcrop of these rocks in the entire region, it is surmised that the rocks of Siddipet area form a part of a major NW plunging anticline with an overturned western limb and with the nose of the fold being near the Godavari river.

Two relict levels of erosion over the Nilgiri are recognised within a polycyclic and polygenetic planar Nilgiri surface. Landform study suggests a pediment cycle for the Ootacamund landforms, the younger of the two relict landforms. The older Dodabetta landforms now stand as vestiges of the original ground at higher elevations. Climate might have been less humid over a major part of this region during the period of pedimentation (post-Miocene) compared to earlier and later times. The Quaternary lowering of temperature in Pleistocene and subsequent warming up of climate are likely to have resulted in the formation of swampy courses, alluvial tracts and peaty subsoils along certain streams over the Nilgiri.- Geomorphology of Visakhapatnam, Andhra Pradesh

The major geomorphic units of the town of Visakhapatnam are the hill slope elements of free face and debris slope, along with piedmont fans, colluvium and pediment. Waltair Uplands are mainly made up of small detached hills, large accumulations of red sands, often dissected into miniature badlands, and patches of dune sands. Laterites are present both as altered product of hard rock as weIl as colluvium. The coastal zone contains stacks, wave-cut platform, beach and sand dunes. A study of logs of more than 1000 bores put in the tidal basin and features reported and observed here and elsewhere along the coast indicates that during the commencement of Holocene (since 10,000 years B.P.), the sea level might have been about 7 metres higher than the present sea level before it went down to as low as 25 metres and rising again to the present level.- Photo-Geomorphic Features in Chintapalle Area Over Eastern Ghats in Andhra Pradesh

Study of aerial photographs of an area of about 2000 sq km around Chintapalle in Visakhapatnam district of Andhra Pradesh, shows that broad structural trends are clear only where there are no laterite caps. The lateritic cappings show off on higher altitudes with light tone and generally across structural trends. The cappings, aligned ENE-WSW with a general altitudinal accordance, are suggestive of their occurrence over remnants of a single planar surface. The criteria identified may be applicable elsewhere in the Eastern Ghat terrain for locating lateritic cappings. Such an exercise appears vital in the present context, as many of the laterite caps of the Eastern Ghats are proved to be good bauxite deposits.- C. Borreswara Rao 1929-1979

The terrain between the Godavari river in the south and the Mahanadi river in the north, comprising about 50,000 sq. km area forms the study region. LANDSAT imagery and aerial photographs were studied with a view to delineate the fracture patterns and analyse their possible significance. The frequency azimuth rose diagrams of fractures indicate two sets of preferred orientations in ENW-WSW and E-W directions. The possibility of some of these fractures/fracture traces being relatively very much younger to the main Eastern Ghat orogeny is a tentative surmise made from this study. These younger fractures may be related to a cymatogenic upwarp during mid-Tertiary.- Coastal Geomorphology in India
