Abstract

The Atomic Minerals Division of the Department of Atomic Energy carried out Airborne Scintillometer surveys for uranium during the period 1957-62, in parts of Andhra Pradesh, Bihar, Gujarat, Madhya Pradesh, Madras, Mysore, Orissa, Rajasthan and West Bengal, totalling more than 74,000 sq. miles, along some 78,775 line-miles in 1401 flying hours. A brief account of the survey operations reviewing the object and organisation of the airborne radiometry, details of the aircraft and equipment used, operational techniques adopted, principles and physical considerations involved in such surveys, basis of interpretation and evaluation of radioactivity anomalies obtained under different environments, results of the survey in various parts of India, utility and future prospects etc., have been given in the paper.

Abstract

A brief account of the geological setting, mineral assemblages, the trace and major element study by chemical and spectrographic investigations etc., of the carbonatic rocks occurring at Newania, Udaipur, Rajasthan, has been given in the paper. Field observations indicate the occurrence of a narrow fenitised zone comprising syenitic rocks, intruded by narrow dykes and veins of carbonatites, signifying development of alkalic character in the rocks, surrounding the main carbonatite body. Locally developed breccia zones and intrusive apatite, vermiculite and calcite veins are also noticed in the rocks. Both the field and laboratory data support the view that these rocks are a special kind of carbonate-rich rocks genetically related to the alkalic rock forming processes and of apparent magmatic origin.
