我省尚未找到单独的或共生的银矿床,已知的银矿主要与铅、锌、铜矿伴生。伴生银矿床类型的划分,根据主要金属元素产出特点和成因类型可分为“三类”、“七型”:即伴生银矿铅锌矿床类、伴生银矿铜矿床类、其他伴生银矿床类;热液充填型、热液交代型、矽卡岩型、沉积再造型、沉积砂岩型、铁锰黑土型、黑色页岩型。根据其成矿的围岩、岩浆岩、构造等条件、以及矿体形态、蚀变、矿物共生组合、银的赋存特征等方面,略述了各类型伴生银矿床的主要地质特征。最后,据我省以往银矿的地质工作情况,以及国家目前对银的需求程度,提出了要加强银矿地质工作的几点意见。
The province has not yet found a single or symbiotic silver deposit, the known silver is mainly associated with lead, zinc, copper. The classification of associated silver deposit types can be classified into “three types” and “seven types” according to the characteristics and types of major metal elements produced: the associated silver-bearing lead-zinc deposits, associated silver deposits, other associated silver Mineral deposits, hydrothermal filling type, hydrothermal replacement type, skarn type, sedimentation re-modeling, sedimentary sandstone type, ferromanganese black soil type, black shale type. The main geological features of various types of associated silver deposits are briefly described according to their metallogenic surrounding rock, magmatic rocks, tectonic and other conditions, as well as ore body morphology, alteration, mineral assemblages and silver depositing features. Finally, according to the geological work of silver mines in our province in the past and the current demand for silver in our country, some suggestions on how to strengthen the geological work of silver mines are put forward.
