Cyanophyta (Girvanella) as Micrite Contributors to Permo-Triassic Limestones of Pirpanjal Range, Kashmir Himalaya
Subscribe/Renew Journal
Two species of Girvanella (G. ducii and G. wetheredii) have been observed during the course of microfacies analysis of limestones of Pirpanjal range. Observations made on three types of Girvanella clasts (tubules, rafts and oncolites) and the associated allochems have revealed calcified algal contribution to the sediments in the form of algal clasts and production of micrite by boring and perforating activities of the Girvanella. The preservation of porous and delicate Girvanella rafts indicates very little reworking prior to transport and deposition.
