河北省寿王坟南沟银金多金属矿床成矿模式与找矿前景

Metallogenic pattern and prospecting prospect of Shouwangfennangou Silver Gold Polymetallic Deposit,Hebei Province

寿王坟南沟银金多金属矿床地处华北地台北缘寿王坟—小寺沟北东向铜钼成矿带,寿王坟—小寺沟Au-Cu-Mo-Ag-Pb-Zn成矿远景区,寿王坟铜矿区外围,具备优越的地层、构造、岩浆岩等成矿地质条件,是寻找火山—次火山热液脉型银金多金属矿床的有利地段。通过对寿王坟南沟银金多金属矿区地质特征、地球物理、地球化学特征,以及矿床地质特征和成矿规律等综合找矿信息的研究,结合区域找矿成果,确定了该矿床热液脉型—斑岩型成矿模式。结合前期工作成果及本次研究表明,该矿区具备了形成中—大型银金矿床的潜力。

The Shouwangfennangou Silver Gold Polymetallic Deposit is located in NE-trending Shouwangfen-Xiaosigou copper-molybdenum metallogenic belt in the northern margin of North China Platform.The Shouwangfen-Xiaosigou Au-Cu-Mo-Ag-Pb-Zn metallogenic prospect area and the periphery of Shouwangfen copper mining area have the superior geological conditions of stratum,structure,magmatic rocks,which are the favorable sections to search for the volcanic-subvolcanic hydrothermal vein type silver gold polymetallic deposits.Based on the study of comprehensive prospecting information on geological characteristics,geophysical and geochemical characteristics,geological characteristics and metallogenic regularity of the deposit,as well as the regional prospecting results,the hydrothermal vein-porphyry type metallogenic pattern of the deposit is determined.The results of the previous work and this study combined shows that this region has the potential to form a medium-large scale silver gold deposit.
