1994-95 To recognise biozones having sTraTigraphical significance To demarcaTe time boundaries boundary wiTh special reference to PlTr To decipher the naTure and significance of evolwion of various palynofloras Palynological study 0[24 samples [rom Satrajpalli area (bore-hole GSP-9) reveals the presence of Barakar palynoflora at 114.00 to 167.00 m depth characterised by the dominance o[ Schellringipollenites while Lower Raniganj palynoflora at 85.04 to 108.80 m is represented by the domi nance o[ striate bisaccate, chiefly Fallnipollenites and STriatopodocarpites and the presence o[ Falcisporites, CrescenTipollenites, LWIOTisporites, Wevlandites and Klallsipollenites. Search, collection and consultation o[ literature [or comparative study o[ Permian Triassic palynoflora o[ India and Antarctica arc continued. Processing and study of samples from bore-holes GLP-6 (38 samples) and GLP-7 (30 samples) of Lakshmidevpet area arc continued. Barakar palynoflora has been observed at46.60 to 66.40 m depth in bore-hole GLP-7; Karharbari at 617.20 to 491.1 Om and Barakar at 327.10 m in bore-hole GLP-6. Restudy of five samples in bore-hole GAM- I0 reveals the presence o[ Talchir p.llynoflora at 58 I.55 m depth. Studies on hore-hole cores GBR-l,2,3,6 and 7 from Budharam area have been linalized. A complete sequence f1"OmTalchir to Kamthi formations (Early Triassic) has heen recorded in this area and a palynological correlation of these hore-cores has been done. Suresh C. Srivastava and Neerja Jha Programme 2.12 Objective Organic petrographic evaluation of coals from Godavari Graben To assess the rank and quality of coal from Mailaram and other areas The maceral, microtithotype and reflectance studies o[ twenty-one coal samples [rom Koyagudem area have been completed. These coals in general are represented by vitrinite and fusinite macerals intimately associated with exinite and mineral matter. Cuticles, sporangia and resins have scanty distribution. Vitrite, ineliite and trimacerite are the common microlithotypes recorded in these coals. The reflectance study has revealed that the coals attained refleetance (Ro max. in oil) value ranging [rom 0.57- I. 3 per cent (normal range 0.57-0.86%), indicating high volatile bituminous C (sub-hituminous A) to high volatile bituminous A stages in rank. However, in some of the samples a sudden rise in the reflectance value has been recorded (0.96-to 1.3%) indicating that these coals have reached high volatile hituminous A to medium volatile bituminous stages. This sudden rise is proh- 91
BSIP ably because or the presence of a rault near the site or collection. A preliminary study regarding Iluorescence characteristics or these coals has indicated the existence or closely packed sporinites. Programme 2.13 Organic petrngraphic evaluation of coal seams frnm Talcher Coalfield Objective To assess coal characterisatiol/ il/ Talcher Coalfield The quantitative estimation or coalmicroconstituents has been carried out Ii'omlhe Lower and Upper workable seams or South Belanda, Bharatpur and Ananta quarries. Besides.the study orliplinitic macerals rrom the above scams havc also bccn carried out under Iluorcscence mode (blue light excitation) and chru'acteristic rorms were pliotomicrographed. Seeds, sporangia. megaspores. resins, cuticles, algal mailer and rragmented Iluorescing malerial represent the chru'acteristic rorms or liptinitic r.-action in the coals. The high incidence or sporinite alongwith inertodetrinile. vilrodelrinite and min ~ral matter and ch,u'acleristic textural pattern ru'c indicalive or the presence or canncl coals al dislinct time levels or Ihe Upper workable seam at Anama QUruTY. The thick-walled cutinites (crassiculinite) were also observed.
