| 中文摘要: |
| 广西大厂矿田100号、105号矿体是世界上罕有的大型特富锡石—硫化物多金属矿体,赋存于巴力—龙头山区生物礁灰岩中。文章对矿体成矿地质背景、矿床地质特征、成矿物质来源和机制,以及生物礁灰岩的组分、结构、构造等控矿因素进行分析研究,表明生物礁灰岩对该区域矿体的形成具有十分重要的作用,是生物有机成矿及构造成矿双重作用的结果,并指出龙头山礁灰岩礁核亚相的骨架灰岩为礁体内最有利的成矿岩性,同时推测出105号矿体深部及边部最有利的成矿部位。 |
| 英文摘要: |
| The No. 100 and No. 105 tin orebodies in the Dachang tin polymetallic deposit area are the largest cassiterite-rich sulfide polymetallic orebodies, which occur in the reef limestone in the Bali-Longtoushan area. Based on the study and analysis of the ore-forming geological background, geological characteristics of the deposit, metallogenic material source and mineralization mechanism, and composition, texture and structure of the reef limestone etc., it showed that the reef limestone plays a key role in the formation of the deposit. The deposit is formed by jointed function of the biological organic process and structural activity. It pointed out that the skeleton limestone of the sub-facies Longtoushan core reef limestone is the most favorable rock. Finally, it is predicted that the favorable metallogenic locations are in the depth of the No. 105 orebody and the surrounding areas. |
