Abstract

Here we present, Anisotropy of Magnetic Susceptibility (AMS) studies on quartzites of Champaner Group, Gujarat, Western India. As quartzites are dominantly present within each formation of the Champaner Group, they have been selected for the study. Our study on AMS signifies two prominent striking planes of magnetic foliation within the rocks. The rocks have (i) ENE-WSW to E-W and (ii) N-S to NE-SW trends. The former trend matches with the regional magnetic foliation of Godhra Granites (GG) and neighboring Banded Gneisses (BG), while the later one does not match with any of the trends resulted due to last phase of deformation within Southern Aravalli Mountain Belt (SAMB). Such heterogeneity among the later trends signifies further continuation of emplacement of GG after syn-tectonic pulse and regional deformation. This latter phase of granite led to the development of broad open N-S trending folds within the supracrustals along with its basement and doming up of sequences towards the eastern periphery of the Champaner Group.
