... of the Chintalapudi Sub-Basin, Godavari Graben, Andhra Pradesh, South India ( Figure 1 ). All the sediments come from the MJR-11 borehole drilled by Mineral Exploration Corporation Limited, in the Gangapur Formation of the Upper Gondwana Group (Lakshminarayana & Murti 1990 ). The objectives of the study were...

...Y. A. Murkute; S. P. Joshi Abstract: The Pranhita-Godavari Graben (PGG) represents a major lineament in south Indian Peninsular cratonic province, which preserves a thick column of sediments. In geological time scale, these sedimentary units correspond to Mesoproterozoic to Mesozoic period...

... and tectonic frame work of the Chintalapudi sub-basin, which is one of the sub-basins of NW – SE trending Godavari graben, using Remote Sensing Data (RSD). The Paloncha structure divides the Gondwana basin of the Godavari valley into Godavari basin to the northwest and Kothagudem and Chintalapudi sub-basins...

...Neerja Jha; Pauline Sabina K; N. C. Mehrotra 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...

...Suresh C. Srivastava; Neerja Jha Abstract The subsurface sedimentary sequences peqaining to the Gondwanas in Budharam Area of Godavari Graben have yielded nearly a complete palynological sequence from Early Permian to Early Triassic represented by Talchir, Karharbari. Barakar. Barren Measures...

...-Godavari Graben. The studies indicate that Barakars of Kamthi sub-basin contain sufficient humic organic matter deposited in intermediate to swampy environment. The organic matter is immature and is capable of generating only gaseous hydrocarbons. Hydrocarbon Gondwana Basins Pranhita-Godavari Graben...

...V. V. Sastri; L. L. Bhandari; R. N. Sinha; Kuldeep Chandra Abstract The Pranhita-Godavari graben, located in the eastern Indian Peninsula, is aligned NW-SE and covers an area of nearly 40,000 sq. km. The graben exposes sediments ranging in age from Proterozoic to Lower Eocene. The oldest...

... to Mesozoic Gondwana sediments were deposited largely in a fault-controlled, successively developed troughs, broadly trending in a northwest-southeast direction. A five-stage tectonic evolution of the Godavari basin is envisaged. Absence of volcanism, and the narrow rift zones, place the Godavari Graben...

... which developed during the separation of India from Antarctica in the Late Jurassic. This rifting episode is superimposed on an earlier northwest-southeast “Gondwana graben trend” such as the Pranhita-Godavari graben (Figure 2a), which extends from onshore into the Krishna-Godavari Basin...

...S. K. Mohinuddin; K. Satyanarayana; G. N. Rao Abstract The NE-SW trending Krishna-Godavari Basin is located at right angles to NW-SE trending Pranhita-Godavari graben ? towards the basin margin. From subsurface exploratory data obtained, it is inferred that NW-SE trending Gondwana graben...

... with the granulite belt of Enderby Land of Antarctica supports the view that the entire region comprised of a single and stable block of granulite rocks prior to the fragmentation of the Gondwanaland. The study also suggests probable continuation of Mahanadi and Godavari grabens into East Antarctica. Marine...

...Bijai Prasad Abstract Palynological studies carried out on the "red beds" encountered in the subsurface sections of Krishna-Godavari Basin establish the occurrence of two distinct red beds; the older of Triassic age, deposited in fluvial intracratonic Pranhita-Godavari Graben and equated...

... the northwest-southeast-trending Pranahita-Godavari graben abuts the basin. The basin contains thick sequences of sediments with several cycles of deposition ranging in age from Late Carboniferous to Holocene. A major delta with a thick, argillaceous facies that has prograded seaward since the Late Cretaceous...

... the Dharwar craton, Cuddapah basin, Godavari graben and the Koyna region, and zone- 1 .b consists of the western margin of the Bengal basin and the Singhbhum craton. Zone - 2 covers the West Bengal sedimentary basin and the Mahanadi coastal basin. Zone - 3 includes Bundelkhand craton and the Vindhyan basin...

.... The least active zone encompasses the Vindhyan syncline and the areas of Delhi and Aravalli folding. Between this zone and the east coast high lies another moderately active zone which encloses the Godavari graben, western part of the Mahanadi graben and the Chattisgarh depression. The b -value seismicity...
