Abstract

Silica-undersaturated potassium-rich igneous rocks and their derivants were earlier considered to be a rare group of rocks occurring in widely scattered localities all over the world (Turner and Verhoogen 1960). During the last three decades however, a large number of localities have been described, where these rocks are reported. They are therefore, much more abundant and widespread than previously thought of (Gupta and Fyfe 2003).
