Overview

Microgravimetry is a rising and important branch developed on the foundation of classical gravimetry. This book contains theories, methods, techniques as well as applications of microgravimetry. The theoretical problems of microgravimetry which differ from ordinary gravimetry, special apparatus and observation techniques, unique data processing and correction methods are discussed extensively. Moreover, examples of microgravimetry surveys conducted both in China and abroad are introduced briefly.
