"""The book deals with several controversial aspects, and analyses and gives pragmatic solutions. Despite scarce and scattered data on the Precambrian tectonics, an attempt has been made to stitch these together to draw a cohesive picture.... The book will help unlearning of old bias and look for paths untrodden. Must for young enthusiastic workers whose ideas have still not frozen."" --Journal of the Geological Society of India"
