摘要
矿床与海底火山(热泉)喷溢-沉积作用有关,属沉积-变质热液矿床.找矿标志是:深大断裂两侧元古界浅变质岩分布区,背斜翼部之区域断裂下盘层间断裂带及主干断裂旁侧断裂带,硫化物富集带和As、Sb、Hg、W的综合异常.
Deposits dealt with in this paper bear relationship to submarine volcanic (hot spring) eruption andsedimentation and belong to the sedimentary metamorphiosed-hydrotheimal type, with following exploration guides and target areas: the Proterozoic low grade metamorphic rock distributive provinces at theboth sides of a deep fault; interlayer faulted zones at the foot wall of regional fracture belt of an anticlinal limb; faulted zone by the side of a main fracture belt; enriched zone of sulfides; composite anomalyarea of As, Sb, Hg and W.
