recorded in bore-hole TP-8 of Talcher Coalfield. These pollen have angiospeml0id eXine
characters. This provided evidence for the manifestation of angiospemlOus exine characters
during latest Pcmlian. The qualitative assessment of spores and pollen species in Kamthi
sediments indicate presence of marker taxa, viz., Lundbladispora raniganjensis. L. breviG1tla.
L. m/croconata. Densoisporites complicatus. Ringo;porites fossulatus. Goubmlspora
morandavensis. L/lnatisporites pellucidus. L. tethyensis, Playfordiaspora cancel/osa. P
annula/a, Foveosporiles triassfcus, Nevesisporites vela/us, Slaurosacciles minulus. ctc.
The composition suggests a Late Early Triassic age connotation in relation to Damodar
Basin assemblages. The presence of acritarchs specially Micrhystridium in the Late Permian
assemblage is noteworthy. The high frequency of taxa M/lraticavea in association
with other acritarchs is the first record from Triassic sediments of Peninsular India. The
results of bore-hole TP-8 were compiled and finalized.

The palynological analysis of bore-holes TP-9 (318-649-63 m deptJl) and TP-I 0
(385 m depth) reveals presence of palynoflora equivalent to Late Pennian assemblages of
DYe. The assemblage has dominance of Siriatopodocarpites + Faunipollenites WitJlappreciable
frequency of Densipollenites. The marker taxa present are Cyclobaculisporites.
Reticlliatisporites. Potonieitriradites. Navalesporites. Weylandites and Gutl/llapollemte.\·.
This reveals tJle presence of Late Pennian Raniganj coals in Talcher Coalfield. The
Kamthi sediments of TP-IO (352.80 m depth) have shown presence of acritarchs in high
frequency.

The outcrop samples collected from Donmara Colliery of Mand-Raigarh Coalfield
have been processed for spores and pollen. The palynological assemblage recovered is rather
poor both in quality as well as quantity. The genus Scheuringipollenites shows its dominance
in this assemblage. OtJler associated taxa are Striatopodocarpites. Faunipollenites.
Virkkipollenites. Parasaccites, etc. nlis assemblage is comparable to other known Lower to
Middle Barakar palynoassemblages.
A fairly rich megaspore assemblage has been recovcred from the bulk macerates
of the rock samples collected from Talbast area of Athgarh Fonnation in Orissa. The
assemblage is characterised by the prcsence of genera like Verrutriletes. 8acutriletes.
Horstisporites. Minerisporites. Paxillitriletes, etc. The dominance of the genus
Minerisporites has been noticed. This megaspore assemblage is comparable to the
megaspore assemblage from tJle Bhuj Fonnation of Kutch Basin.

Three palynological assemblages have been identified in bore-hole SPB-14 of
Sohagpur Coalfield. In Assemblage-I, at depth 0.00-130.05 m (Middle Pali sediments)
Late Pennian palynofossils-Founipollenite.l'. Striatopodocorpites. Crescentipollenites
alongwith Gondisporites and Dem'/pollenites have been recordcd. In Assemblage-II (depth
225.00-280.00 m, Lower Pali Member), striated as well as non-striated disaccates are in
prominence IJ1 association with Densipollenites and few monosa~cates. nus assemblage
