摘要
老挝琅勃拉邦北部地区锑矿资源较丰富,喷同锑矿区主要出露粉砂岩和碳质板岩,其中碳质板岩为矿区的赋矿层,矿体呈透镜状、脉状等产于碳质板岩中的断裂和揉皱滑脱部位,矿石类型为辉锑矿,主要呈块状和针状集合体产出。矿化可能与岩浆岩关系不大,而是与构造形成的热液活动和碳质板岩围岩有关。
Antimony mineral resources are abundant in the northern part of Langbrabang,Laos.Siltstone and carbonaceous slate are mainly exposed in the Gutong antimony mining area.Carboniferous slate is the ore-hosting stratum in the mining area.The ore bodies are lenticular and vein-like,occurring in the fracture and crumpling-slipping parts of carbonaceous slate.The ore type is stibnite,mainly occurring in massive and acicular aggregates.Mineralization may not be related to magmatic rocks,but to tectonic hydrothermal activity and carbonaceous slate wall rocks.
