This work 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. It details the following topics: geochemistry of selected low-temperature deposits of prospects (horizons); geochemistry of elements during diagenesis, buried metamorphism and low-grade metamorphism; re-mobilization, transport and precipitation of some ore-forming elements under low-temperature conditions; water/rock interactions in low-temperature open systems. Low-temperature geochemistry deals with geological and chemical processes, and the geochemical evolution of elements in nature below 200 centigrade, including mineralization at room temperature and below 0 centigrade.
