Meso-scale flanking structure and micro-scale push up structure within migmatitic biotite granite, Peninsular Gneissic Complex, Southern India
We hereby report the occurrence of meso-scale flanking structure (Fig. 1; a: original, b: annotated) and micro-scale push up structure [observed in a pyrite (Py) grain, Fig. 2; a: original, b: annotated], developed in sheared Migmatitic Biotite Granite of Peninsular Gneissic Complex (PGC-II) of Dharwar craton, southern India. Flanking structures in shear zones were paid first due attention by Passchier (2001) and subsequently studied in details by Grasemann et al. (2003), Mukherjee and Koyi (2009) and Mukherjee (2011a, 2014b, 2015). The migmatite section displays an ‘eye-catching’ flanking structure in meso-scale (Fig. 1). The host element (HE) is described by leucosome and melanosome bands with the cross-cutting element (CE) being the fracture plane. The HE shows positive Description
