Structural Concepts in Field Geology - the first Field Excursion organized by APG Delhi Chapter

On 10th February 2007, the Delhi Chapter of Association of Petroleum Geologists organised a geological field trip for its members at a section 6 kms from Behror on Behror - Narnaul highway in Rajasthan. Over 20 participants were the Delhi Chapter’s members from ONGC, DGH, IOC and Cairn Energy.

Under the guidance of Professor A. M. Bhola, an eminent structural geologist and Head of the Geology Department, University of Delhi, the members of APG Delhi chapter had an unforgettable opportunity to relive their own field trips made way down the memory lane.

The exposed outcrops of Delhi super group of Meso Proterozoic age are deformed by three phases of well preserved folding affecting bedding and coevally developed slaty cleavage, dipping northeastwards. Prof. Bhola beginning with the strain ellipsoid concept demonstrated on the ground, different stages of folding, the geological features originating from these and their hierarchy in time.

The trip can be simply underlined for emphasis in view of the enhanced value of outcrop geology in the new vistas opened by sequence stratigraphy in petroleum exploration.
