中国银矿床银的赋存状态与富集机制
The Occurrence State and Enrichment Mechanism of Silver in China Silver Deposits
摘要
Abstract
The research reveals that silver mineralization spans a wide geological time frame,from the Cambrian to the Neogene periods.The forms of silver occurrence in various types of silver deposits exhibit significant differences.In hydrothermal silver deposits,silver primarily occurs as independent silver minerals,with less in crystal lattice form.In marine volcanic silver deposits,silver occurs mainly as independent silver minerals and crystal lattice silver.In terrestrial volcanic-subvolcanic silver deposits,silver predominantly exists as independent silver minerals.In skarn-type silver deposits,silver is primarily in the form of crystal lattice silver,followed by independent silver minerals and microscopic inclusions.In sedimentary and metamorphic silver deposits,silver primarily occurs as crystal lattice silver and independent silver minerals,with a small portion in organic form.The forms of silver occurrence are influenced by regional geochemical conditions,combination of ore-forming elements,and ore-forming conditions.Fluids,temperature,pressure,and pH are key factors controlling the concentration and precipitation of silver.Volatile components in fluids(F,Cl,HS-)facilitate the migration of Ag+,and temperature and pressure reduction,along with pH increase,promote the concentration and precipitation of silver,affecting its forms of occurrence.关键词
