Overview

Low-temperature geochemistry -- a 'hot topic' in geochemistry at present -- deals with geological and chemical processes and the geochemical evolution of elements in nature below 200C, including the geochemical behaviour of elements in the processes of their extraction, remobilization, transport and mineralization at room temperature and below 0C. This book focuses on the low-temperature geochemical behaviour of precious metals, REE, some individual dispersed elements and some non-metallic elements and their minergenesis at low-temperatures. The book deals with the following topics: 1) geochemistry of selected low-temperature deposits or prospects (horizons); 2) geochemistry of elements during diagenesis, buried metamorphism and low-grade metamorphism; 3) remobilization, transport and precipitation of some ore-forming elements under low-temperature conditions; 4) water/rock interactions in low-temperature open systems
