Abstract

Geologically the area around Naswadi comprises Precambrian metamorphics and granite, Bagh Beds and Deccan Traps. The various formations have been dislocated at several places owing to tectonic movements along the Narmada Rift Zone. Most of the fau1ts lie parallel to the main Narmada lineament, e.g., ENE-WSW, and they have been further dislocated by NW-SE fractures.

Abstract

Famous ring-like body in Ambadongar, intrusive dykes and other linear features are quite conspicuous in the satellite images of the Lower Narmada valley region. Field investigations have confirmed that some of the dykes and linear features seen south of Ambadongar are carbonatite intrusives. while most others are of dolerite dykes. Two earbonatite dykes in the northern portion, one major carbonatite dyke and a few minor ones in the southern portion were traced in the field. Carbonatite dykes in this region have been silicified and an increase in the degree of silicification is noticed southward.
