笔者在系统研究尕科合银砷矿床成矿地质背景和矿床地质特征的基础上,重新厘定了矿区赋矿地层层序,探讨了尕科合石英闪长岩体与矿化的关系。结合成矿物理化学条件和氢、氧同位素的研究,阐明尕科合含铜银砷矿床成矿物质主要来源于印支晚期岩浆侵入活动中的岩浆气液,属于岩浆中温气液矿床,并与西邻的赛什塘铜矿床构成与印支晚期中酸性侵入活动有关的铜(铅锌)-银砷成矿系列。
On the basis of systematically studying the metallogenic geological background and geological characteristics of the Gakeheyin arsenic deposit, the author redefined the stratigraphic sequence of the ore-bearing strata and discussed the relationship between Ga-Co-quartz diorite and mineralization. Based on the study of physicochemical conditions and isotopes of hydrogen and oxygen, it is clarified that the ore-forming materials of Cu-Cu-Cu-Ag-As deposit are mainly derived from magmatic gas-liquid in the Late Indosinian magmatic intrusive activity, The nearby Saishitang copper deposit constitutes a series of copper (lead-zinc) -silver arsenic mineralization related to the late Indosinian acid-intrusion.
