Abstract
1. The igneous complex shows a remarkably complete series of types from ordinary biotite granite, through contaminated granite, intrusion gneisses, lit-par-lit aplitic intrusions, to aplites and muscovite pegmatites. 2. Pale-coloured reaction zones occur between xenoliths and the granitic masses. The evidence points to an exchange of material between xenoliths and the surrounding magma. 3. All the rocks are mylonized and it is suggested that the micro-structure can only be explained by movement during the final stages of crystallization. The folding is believed to have taken place in late Mesozoic times, as the area forms part of the Indo-Malayan Mountain System.
