摘要
龙山金锑矿床赋存于震旦系下统江口组上段含砾砂质板岩中,矿体严格受构造和地层岩性的控制,圈岩蚀变强烈,碳酸盐化、毒砂一黄铁矿化、水云母化形成明显分带性,其强度、宽度、分带性与金锑矿化富集关系密切。
Longshan Au-Sb deposit occurs in pebble-bearing sandy slate of upper Jiangkou formation, lower Sinian system. Orebody is strongly controled by structure and lithology of strata. Wall-rock alteration is intense-ly. Carbonatization; Arseno-pyritization; Hydromuscovitization from obvious zonation. Enrichment of Au-Sb mineralization strongly relates with wall-rock alteration’s strength; width and zonation.
