Structural Analysis of Ranikot Anticline, Southern Kirthar Fold Belt, Pakistan

Abstract

In this paper, different applications of stereographic projections are utilized for the structural analysis of Ranikot anticline. Structural data of Ranikot anticline from Southern Kirthar Fold Belt of Pakistan is used to construct different diagrams such as beta-diagrams, pi-diagrams and contour diagrams. These diagrams are used to visualize the inter-limb angle, plunge and trend of fold axis, dip and strike of axial surface, fold symmetry, vergence and principle stress axes. This study shows that studied anticline is nearly N-S trending, open, shallow to horizontal, asymmetrical, and east-vergent anticline. Principle stress axis σ1 and σ2 lie in profile plane while σ1 and σ3 lie in axial surface.
