摘要
通过对天子坪金矿地质特征的描述,通过对矿床的区域地质背景、矿区地质特征、地球化学特征、控矿因素及找矿标志等方面的研究,认为天子坪矿床为典型的卡林型金矿床成矿模式,成矿物质来源为岩浆岩(八卦山)和地层(下古生界泥盆纪舒家坝组),高桥一罗坝断裂及其两侧的张性次级断裂为矿床的导矿、容矿断裂,在总结了天子坪金矿找矿标志的同时提出了今后的找矿方向。
Based on the description of the geological characteristics of tianziping gold deposit and the study of its regional geological background,geological characteristics,geochemical characteristics,ore controlling factors and ore prospecting indicators,it is considered that tianziping gold deposit is a typical Carlin type gold deposit metallogenic model,and the source of ore forming materials are magmatic rock(Baguashan)and strata(Lower Paleozoic Devonian Shujiaba formation),Gaoqiao Luoba fault and its secondary faults on both sides are ore guiding and ore bearing faults of the deposit.
