豫西铝土矿床地质特征及三维地质建模

Geological Characteristics of Bauxite Deposits in the West of Henan Province and 3D Geological Model

豫西铝土矿床产于寒武系-奥陶系长期风化侵蚀面之上的石炭系本溪组中,综合矿床成因和找矿标志,寻找有形成大型矿床潜力的地区。铝土矿矿石为一硬水铝石型铝土矿,经过多年的探采,已从找露头矿进入到找隐伏矿时期。三维可视化技术在铝土矿体的运用有利于寻找深部隐伏巨富矿体,建立了一种适用于铝土矿的三维建模方法,同时剖析了铝土矿形成富矿的三维空间展布及相互关系。

The Bauxite deposit in the west of Henan province is located in the Carboniferous Benxi Formation over the long-term weathering erosion of the Cambrian and Ordovician. By the mineral deposit genesis and the prospecting flags, the bauxite is discovered in the potential areas to form large deposits. after years of exploration,it has been a stage from the outcrop mine to explored hidden ore period. 3D visualization technology in the use of bauxite ore body is conducive to search for deep hidden ore period. A 3D modeling suitable method was established for bauxite, and 3D space distribution and correlation of bauxite ore-forming were analyzed.
