Abstract

Abstract

A suite of Neo-Archaean tonalitic-trondjemites-granodioritic intrusive rocks composed mainly of diorites, quartz diorites, and tonalites are discovered in Guyang district, Inner Mongolia through the regional mapping. Although these intrusive rocks have been metamorphosed to some extent, their relatively perfect appearances quite different from those of the Archaean gray gneisses can still be observed. These rocks within the calc-alkali series are a part of the TTG rock series. The isotopic dating indicates that the age of the rocks at 2 400-2 500 Ma, i.e. at the end of Neo-Archaean.
