Petrography and mineral chemistry of Alkaline-Carbonatite Complex in Singhbhum Crustal Province, Purulia region, Eastern India
S. K. Basu,Tapas Bhattacharyya +1 more
TL;DR: The variant rock types of an Alkaline-Carbonatite Complex (ACC) comprising alkali pyroxenite, nepheline syenite as discussed by the authors, phoscorite, carbonatite, syenitic fenite and glimmerite along with REE and Nb-mineralization are found at different centres along WNW-ESE trending South Purulia Shear Zone (SPSZ) in parts of Singhbhum Crustal Province.
Journal ArticleDOI
Origin of Pseudotachylytes Based on Clasts Size Frequency Distribution in Bundelkhand Craton, Central India
TL;DR: Size frequency diagrams of clasts show power law distribution pattern for crushing dominated pseudotachylytes and “left hand fall off” or curvilinear pattern for melt affected pseudotachedlytes.
Journal Article
Primary and secondary features in the Anasagar Gneiss near Ajmer and their implication on the evolution of the proterozoic south Delhi Fold Belt, Central Rajasthan
Journal ArticleDOI
Structural framework of the transpressive Mahanadi Shear Zone and reevaluation of the regional geology in the northern sector of the Eastern Ghats Mobile Belt, Eastern India
TL;DR: In this article, the authors showed that the width of the Mahanadi Shear Zone (MSZ) extends beyond 38 km. The MSZ is a transpressional zone with simple shear along and pure shear perpendicular to the mylonitic fabric.
Journal ArticleDOI
Influence of continental rifting on sedimentation and its provenance and geodynamic implications: An example from late Paleoproterozoic Chandil Formation, eastern India
Priyanka Chatterjee,Shuvabrata De,Rajat Mazumder,Rajat Mazumder,Tohru Ohta,Jeffrey R. Chiarenzelli,Tapas Bhattacharyya +6 more
TL;DR: The Chandil Formation has been divided into three distinct sedimentary facies associations: the bottommost trough cross-stratified, poorly sorted and texturally immature, coarse- to medium-grained sandstone-shale facies association formed in a fluvial setting as mentioned in this paper.
