Sporological succession in Kota and Turra seams, Singrauli coalfield (M.P.), India

Abstract

Quantitative analysis of miospore genera in Kota and Tuna seams of Singrauli Coalfield has revealed that zonate trilete genera Indotriradites and Dentatispora, along with Sulcatisporites, Callumispora and Brevitriletes form the dominant association in the former while Sulcatisporites, in association with Indotriradites, Parasaccites and Brevitriletes contributes maximum to the assemblage in the latter seam. That the two miofloras show closer alliance with the Lower Barakar Stage, is evident by the prominence of zonate trilete genera. The frequency behaviour of various generic groups in successional coal deposits of Singrauli Coalfield has been also discussed.
