“…Thus, the present assemblage is comparable to the older horizon of Talchir Formation. It is also closely comparable to the other known assemblages of Talchir Formation recovered from South Rewa Gondwana Basin at Goraia (Potonié & Lele, 1961); from Jayanti Coalfield (Lele & Karim, 1971;Lele & Makada, 1972) and from Mohpani Coalfield (Bharadwaj & Anand-Prakash, 1972). Lele & Chandra (1973) also described a Talchir Assemblage from Johilla Coalfield which is rich in Rugasaccites along with Plicatipollenites and Parasaccites.…”

Palynological studies were undertaken on the sediments of Talchir Formation exposed along a stream cutting in the Tatapani-Ramkola Coalfield, Chhattisgarh State, India. The glacigenic nature of the Talchir Formation is evident, as manifested by the presence of lithified tillites, varves and rafted boulders. The varve clays have yielded a well preserved assemblage rich in radial monosaccates. The assemblage is dominated by Plicatipollenites (26-31%) with a sub-dominance of Parasaccites (8-22%). Potonieisporites, Virkkipollenites, Caheniasaccites and Sahnites are the other important constituents. The recovered palynoflora is characteristic of Plicatipollenites-Parasaccites palynoassemblage, which represents Lower Talchir palynozone and is of early Permian age.

“…In India, the Parasaccites+Plicatipollenites palynoassemblage from the present study is correlatable with the Parasaccites+Plicatipollenites palynoassemblages from Godavari Basin (Srivastava & Jha, 1989), South Rewa Gondwana Basin (Potonie & Lele, 1961), Jayanti Coalfield (Lele & Makada, 1972), Korba Coalfield (Bharadwaj & Srivastava, 1973), West Bokaro Coalfield (Lele, 1975), Giridih Coalfield (Srivastava, 1973 and Manendragarh Coalfield (Bharadwaj & Srivastava, 1979), which are characteristic of Upper Talchir palynoflora. While the Parasaccites+Callumispora palynoassemblage from the present study is correlatable with the palynoassemblages SC-I and SC-II of the lower most workable Saharjuri coal horizon (Hait & Banerjee, 1994); the palynoassemblage from North Karanpura Coalfield of Damodar Basin (Mukherjee & Ghosh, 1972); Zone -2 of Pusai Shampur area, of Raniganj Coalfield of Damodar Basin (Tiwari, 1973); palynoassemblage from the Jharia Coalfield of Damodar Basin (Tiwari et al, 1981); the microfloral Zone-2 of Umaria Coalfield of South Rewa Basin (Srivastava & Anand Prakash, 1984) and Zone-1 of Tatapani-Ramkola Coalfield of Koel-Damodar Basin (Kar & Srivastava, 2003) in having dominance of Parasaccites and subdominance of Callumispora, typical of the Lower Karharbari palynoflora.…”

Palynological studies have been carried out in the subsurface sediments of borehole CMWY-95 drilled near Pisagaon in Chandrapur District of Maharashtra. The studies have been aimed to palynologically date and correlate the sediments. On the basis of the statistical analysis of the spores and pollen from the productive samples, two palynoassemblages have been demarcated: Assemblage I recognised at a depth of 149.00 m is characterised by the dominance of the monosaccate genus Parasaccites and subdominance of Plicatipollenites which is typical of the Early Permian Upper Talchir palynoflora and Assemblage II identified between the depths 147.00-133.00 m is characterised by the dominance of Parasaccites and subdominance of Callumispora which corresponds to the Early Permian Lower Karharbari palynoflora. Therefore, palynologically these sediments have been dated to be of Early Permian age. Further, within India, an inter and intra basinal correlation has been attempted while with the continents of the Gondwanaland- Africa, Australia, Antarctica and South America, it is observed that the correlation with Antarctica is closest when compared to other continents suggesting a closer genetic relationship with Antarctica. A close similarity with the Early Permian palynosequences of Africa than that of Australia has also been noticed due to regional differences amongst eastern and western Australia, while in South America correlation was feasible only in broader pattern of group occurrences as the differences were pronounced at finer levels.

“…The Boulder sequence is topped by a greenish Needle Shale member. These field observations lead to believe that the Boulder Bed in the J ohi Ha Coalfield occurs in repetitions much in the same way as in the Jayanti Coalfield ( Lele and Karim, 1971) and several other basins (Lele, 1966). Material and Methods -Samples from all the four beds from the above section were macerated in the usual manner using HF acid and mounted in polyvenyl aJcohol followed by Canada Bals?,m.…”

“…Bed became known only recently when Lele & Karim (1971) described well pre~erved miofloras from the two Talchir Boulder Bed intercalations of the Jayanti Coalfield. The present findings from Mangthar (Johilla Coalfield) furnish yet another example of a similar occurrence of mioflora in the Talchir Boulder Bed and the overlying Needle Shales.…”

Miospore assemblages are, for the first time, recorded from the Talchir Boulder Bed and overlying Needle Shales in the South Rewa Basin: The Boulder Bed assemblage contains 13 genera and 20 species, while the Needle shales have 17 genera and 24 species. Both assemblages, having several common taxa, are predominated by monosaccate pollen as is generally characteristic of other known Talchir miofloras. In the details of composition, however, the Boulder Bed assemblage of South Rewa appears to be distinct from that recorded from similar sediments of the Jayanti Coalfield. The present findings lend further support to the existence of the Glossopteris Flora during course of the Gondwana glaciation.
