| 中文摘要: |
| 黔北务正道地区是贵州重要的铝土矿成矿区。研究表明,铝土矿产于中下志留统韩家店组(S1-2hj)页岩或上石炭统黄龙组(C2h)灰岩侵蚀面上,含矿层位为中二叠统梁山组(P2l),赋矿围岩主要为炭质页岩和铝土质页岩。铝土矿床形成于河湖沼泽沉积环境,分布严格受NE向向斜构造控制,矿层连续性好、埋藏大,矿石品位高、铝硅比高。矿床成因属古风化壳沉积型。 |
| 英文摘要: |
| Wuchuan-Zheng'an-Daozhen region is an important bauxite mineralizing area.It is shown that bauxite ores occur in shale of lower middle Silurian Hanjiadian formation(S1-2hj),or on the limestone erosion surface of upper Caroniferous Huanglong formation(C2h).Ore-controlling strata are middle Permian Liangshan formation(P2l),and hosting rocks are carbonaceous and allitic shale.Bauxite ores with fine continuity,thick embedding,higher ore content and high Al/Si,are formed in the lake and stream sedimentary enviro... |
