Strain analysis of Jonk River Conglomerate, Sonakhan Greenstone Belt, Distt – Balodabazar, Chhattisgarh
Journal Title: Bulletin of Pure and Applied Sciences Sec. F –Geology - Year 2018, Vol 37, Issue 2
Abstract
The Jonk River Conglomerate refers to the structure where the outcrop pattern in the area include pebbles lineation developed due to parallel arrangement of stretched pebbles, fold axis and intersection lineation developed due intersection of S0 and S1. Two deformations event have affects the Sonakhan Greenstone Rocks. The second phase of deformation is represented by broad and open flexures (F2) having NE-SW trending axial planes. Strain analysis on the five arbitrarily chosen structural domain (D1 – D5) from the area was performed in YZ section with Elliott polar plot, Fry methods and whole rock strain analysis was performed by Flinn methods and logarithmic Flinn methods. The strain data show that conglomerate from the area exhibit Flattening to plain strain ellipsoid. The strain results of Flinn methods and Logarithmic Flinn methods show consistent volume loss and shortening from D1 to D5.
