Structural Anatomy of the Intraterrane Shear Zones in the Archean Bundelkhand Craton, North-Central India and Its Possible Linkage to Supercontinent Assembly: Insights from Field- and AMS-Based Kinematic Analysis

Abstract Delineation and characterization of the intraterrane shear zones (ITSZs) are very significant in establishing suitable models to understand tectonic evolution continental blocks often provide crucial information on supercontinent assembly. The granitoid rocks Bundelkhand Craton (BC) host mesoscale ductile varying width direction typically represent decoupling (high low strain), characteristic ITSZs. detailed study structural anatomy nucleation BC suggests presence four distinct sets ITSZs along ~N-S, ~NE-SW, ~NW-SE, ~ E-W directions. is possibly a result reactivation precursor fractures due rheological transformation induced by fluid phase, which percolated through fractures. Also, thickness ultramylonite zone attributed style brittle fracturing. Here, we also construe relative chronology development fabric elements related with help cross-cutting relationships as observed field further corroborated it available chronological data. This suggests, ~E-W trending (BTZ) Raksa (RSZ) oldest followed NW-SE kinematic analysis these ITSZs, angular relationship between measured mylonitic foliation determined magnetic data (by AMS analysis), that dominantly governed general except shows pure dominated progressive deformation. evidences analysis, conclude transpression was involved over protracted period for BC. Finally, argue BTZ served site localization represents amalgamation North South during formation Kenorland.
