Abstract

First record of Type I matured, Liptinite organic matter facies from the Gotan Limestone (Late Neoproterozoic) in Rajasthan is considered significant. This throws open an entirely new basin for hydrocarbon exploration from the Neoproterozoic sediments in Rajasthan and other similar prospective basins in India. The palynological assemblage recorded from the studied samples also contains larve of the petroleum fly Helaeomyia (=Psilopa Coquillet) petrolei, known to live in pools of crude petroleum. The significance of the find is discussed in this brief communication.

Abstract

Plant mega- and microfossils are reported in the bore core 726 from Manuguru area, Godavari Graben, Andhra Pradesh. Plant megafossils Gangamopteris sp., Glossopteris indica, G.subtilis, G. sastrii, Glosspteris sp. cf G. teluinervis, Glossopteris sp. and equisetalean axes are recorded in the sediments lithologically identified as Baraker Formation while Noeggerathiopsis hislopii, Glossopteris communis and G. stenoneura occur in the sediments lithologically recognized as Raniganj Formation. Plant microfossil studies carried out in these sediments reveal presence of three palynoassemblages, one belonging to Barakar Formation at 596-636 m and two belonging to Raniganj Formation at 379-580 m. A review of distribution of plant megafossils in Permian sediments of Godavari Graben reveals that the megafloral taxa of present study have been recorded for the first time from the Lower Gondwana of Godavari Graben. A comparative analysis of mega- and microfloral assemblages with the known stratigraphic age of Lower Gondwana sediments of Godavari Graben has also been attempted.

Abstract

42 genera of palynomorphs have been reported from the qualitative and quantitative analysis of the palynoflora from both open cast mine and bore holes viz., Ballarpur open cast mine, Durgapur open cast mine and Bore hole CMWNM-57 on barrier between Kawadi/Majri open cast and Hindustan Lalpeth Colliery from the Wardha valley coalfield of Wardha basin. Two palynoassemblages have been recorded i.e., an Upper Karharbari palynoassemblage comprising dominance of radial monosaccate genus Parasaccites and subdominance of nonstriate disaccate genus Scheuringipollenites and a Lower Barakar palynoassemblage consisting of dominance of Scheuringipollenites and subdominance of striate disaccates chiefly Faunipollenites, suggesting an Early Permian age (Late Sakmarian to Early Artinskian) to the sediments. It is further authenticated by the occurrence of palynotaxa viz., Crucisaccites, Caheniasaccites, Indotriradites and Tiwariasporis. Upper Karharbari Formation has been demarcated for the first time in lithologically designated Barakar Formations in Ballarpur, Durgapur, Majri and Hindustan Lalpeth Colliery while the sample 57/2 of bore hole CMWNM from Kawadi area may belong to the Kamthi Formation on the basis of pinkish yellowish coarse grained to medium grained sandstone. An attempt has been made to correlate these palynoassemblages with other Lower Gondwana basins of Early Permian affinity.

Abstract

Palynological analysis of the subsurface sediments from the bore hole 1008 (PK-6&7 blocks) from Manuguru area of Godavari graben has revealed the presence of Early Triassic palynoflora. Quantitative and qualitative palynological analysis of the productive samples have shown that the palynofossil content is predominated by cingulate-cavate spores, viz. Lundbladispora and Densoisporites and taeniate pollen like Lunatisporites in association with other taxa, such as Falcisporites, Alisporites, Klausipollenites, Chordasporites, Verrucosisporites and Osmundacidites. The above recovered palynoflora provides conclusive evidence for the presence of Early Triassic sediments equivalent to Panchet in the Manuguru area of Godavari graben. This is the first record of Early Triassic palynoflora in the Manuguru area. This corroborates the findings of Jha and Srivastava (1996) that the Lower Kamthi Formation represents the Early Triassic sequence equivalent to the Panchet Formation.

Abstract

Subsurface sediments of a 120 cm deep trench from Ny-Alesund, Svalbard, were analysed for pollenspores and other organic matter contents. This study is supported by two AMS ¹⁴C dates (27, 200 yrs BP and 8,762 yrs BP) at the bottom and topmost litho-unit of the trench, respectively. The pollen record provides an evidence of a warm interval at about 27,200 yr BP (Late Weichselian and MIS 3) and cooling episode around 8,762 yr BP. This is also supported by the amount and type of organic matter as well as sediment type and depositional history of the trench sediments.
