6 from the Horth-western part of the Karanpura Coalfield, Bihar have been completed. 2.5.5. Tanzania Palynostratigraphic studies sediments have been completed of and the the Lower Permian results have been compiled for publica (ion. 2.6. Petrology and palynology of Palaeozoic coals 2.6.1. Biostructural features of Permia1l coals of [ndia Permian coals reveal varied biostructures and tbese depend on the source material of the coal forming swamps. Some of the organic entities are bark, wood, spore, pollen and cuticles apart from the inorganic constituents. The organic cnti ties ~uggest genetic affinities by' their biomorphological features. The ultimate coal formation depends on structural and compositional nature. 2.6.2. Typological analysis of Permian coals The cOlllpositional distribution of coal constituents suggests that V/F ratio is most conspicuous in the organization of organic constituents. The proportion of other microconstituents combine to form several coal microlithotype. 2.6.3. Maturation of Permian coals The degree of maturation is of primary importance In the evaluation of coals for technological utility. The general trend of maturation values ranges from sub~bituminous to bituminous ranks. However, the localized higher rank values have been recognized owing to igneous activities.
7 2.6.4. Interrelationship of Permian coo/lithotypes Lithotypes of the Permian coals show interrelationship. Some of the related types are durofusain, vitrofusain, clarofusain, in Fusain; fusoclurain, vitrodurain and clarodurain, in Durain; duroclarain, vilrociarain, fusoclarain, in Clarain. These all form tetrahedral type of Permian lithotypes. 3. MESOZOIC 3.1. Megafossil Assemblages 3.1.1. TriaSfic Flora Out of a large number of seeds ha\c been isolated from the Nidpur shale samples. Their epidermal feature have been [ounl! to be quile different from the hitherto known seed genera from this locality. Peel preparations from a gymnospermous cOIle have yielded PraecQlpatites type of pollen grains. The epidermal features of the microsporophylls arc somewhat to the epidermal characters of JVidia ovalis described Ly Bo~c alld Srivastava (1973). 3.1.2. }urassic-Cretaceour Flora The work on the cycadophytic leaves from the Mesozoic rocks of India was contmued. In connection with the \-\'ork on the Lower Cretaceous flora uf India the first draft con· cerning the description of Equiseturrt rajmahalense, Gleichenia tl ordenskioldii, Phlebopteris pol)'/Jodioides, IVeichselia reticulata, a few species or Cladophlebis, Sphenop'ens, Pachypteris indica, Ginkgo feis/mantelii, species of P/i/ophyllum and B"achypl!J'llum has been prepareJ. A new species of Ctenozamites from the Satpura basin is under study. Some gymnospermous cuticles isolated by bulk maceration from the shale samples from Parsapani are under study.
