Abstract

Detailed mapping and analyses of the structural elements from Gorimari revealed a complex structural geometry and deformation history of the rocks. Only two prominent planar structural elements have been observed i.e., the bedding schistosity (S₀S₁) and cleavage (S2). The earliest AF1 and the later AF2 folds on every scale are suggestive of reclined geometry. The strain analyses of AF1 and AF2 folds suggest their initiation by buckling and subsequent flattening resulting into class I C geometry. Some of the folds show a complex geometry which may be due to original layer irregularities or may be due to differential flattening because of the variation in thickness of single layer. The values of compressive apparent strain ratio varies from 0.1 to 1.0. Stratigraphically these rocks are equivalent to the Early Proterozoic rocks of Bagdunda. The grade of metamorphism is oflower amphibolite facies.

Abstract

The Geology Department of Mohanlal Sukhadia University, Udaipur, Rajasthan organised a National Field Based Workshop on, “Litho-tectonic controls of Mineralization”, FBW-2011 during September 17- 19, 2011 as a sequel of the Golden Jubilee Celebration of the University. Faculty members of the Department of Geology, MLS University, Udaipur, officers from the Directorate of Mines and Geology, participants from various universities and government organizations, research scholars and P.G. students of geology department actively participated. In all about 45 geoscientists from different parts of India participated.
