“…Lele andChandra (1969, 1972) reported Talchir assemblages including acritarch-like microfossils from this area. In 1971, Saksena described the dispersed palynofossils from the Ganjra Nala Section, while Lele and Chandra (1973) gave detailed account of palynological assemblages from this area. Thereafter, Chandra and Lele (1979) recovered palynofloras from Talchir Formation of Birsinghpur Pali, Anuppur, Chirimiri, Manendragarh and Umaria areas and established two major palynological zones-Plicatlpollenites-Parasaccites miofloral Zone and Parasaccites•Plicatlpollenites Zone within the Talchir.…”

The dispersed spores and pollen grains preserved in the sediments exposed along Johilla River Section, Ganjra Nala Section and in three bore-cores, viz., JHL-23, JHL-24, JHL-25, in Johilla Coalfield have been described. The rich miofloral assemblage consists of 58 genera and 126 species, out of which seven species are new on the basis of their morphological characters. These are - Callumispora paliensls, C. saksenae, Osmundacidites baculatus, Dentatispora mammoida, D. reticulata, Gondisporites reticulatus and Lunatisporites paliensis. On the basis of the composition of spores and pollen grains, it has been concluded that the South Rewa Gondwana Basin shows a broader relationship with equivalent strata in other basins of India. In general, the monosaccate pollen has a better representation in the Talchir as well as Barakar sediments which is suggestive of relatively cooler conditions than those in Damodar Valley. Six palynological zones have been identified on the basis of quantitative analysis.

“…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. The present palynozone also shows a close resemblance to the above mentioned assemblage except, that here genus Rugasaccites is absent.…”

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.

“…Only the palynoflora from the Talchir Formation is relevant, therefore, to the present discussion. The assemblages from the glacigene Talchir Formation were described by Lele and Karim (1971), Lele and Chandra (1973) and Lele (1975). Typical assemblages from the formation contain about 86 per cent monosaccates, 10 per cent disaccates (about 0•5 per cent taeniate) and only 3 per cent trilete spores.…”

Comparison of plant microfossil assemblages in Late Palaeozoic Gondwana glacial sequences

Coeval plant microfossil assemblages of glacigene deposits of Gondwanaland are divisible on the basis of proportions of major morphological groups into two distinct types. They are the Australian-type (with a dominance of trilete spores and up to 10 percent monosaccate pollen) and the Indian-type (dominated by monosaccate pollen with a minor proportion of spores). The lack of diversity of the Indian-type palynoflora is consistent with a parent flora adapted to harsh physical conditions such as a severe glacial environment. The Australian- type palynofloras, by contrast, suggest parent plant communities developed under milder conditions, perhaps peripheral to ice centers or experiencing a greater fluvial influence. Recognition of Australian-type palynofloras associated with coal measure sequences in Tanzania, and coeval with glacigene sequences elsewhere in Gondwanaland may indicate that the post-glacial flora in the Gondwana countries was not simply the result of evolution and radiation in response to the end of widespread glaciation.
