黔北务正道铝土矿找矿标志及找矿模式

黔北务正道铝土矿产于上石炭统大竹园组的中上部，其成矿时代归属晚石炭世马平期。根据矿床就位机制，铝土矿成因类型划属古风化壳型异地堆积铝土矿床。在总结构造、地层、岩石、矿物、放射性、地貌找矿标志的基础上，建立了找矿模式。认为务正道地区地表工作程度一般较高，今后的主要任务是根据区域性的找矿标志及找矿模式，并遵循“从已知到未知”的原则，预测和重视深部找矿，此乃扩大区域铝土矿远景规模的重要途径。

Exploration Guide and Model of Wuchuan-Zheng'an-Daozhen Bauxite Deposit in North Guizhou

Wuchuan - Zhengan - Daozhen bauxite deposit in north Guizhou occurred in the middle and upper part of Dazhuyuan formation, Upper Carboniferous, its mineralization date is Maping period, Late Carboniferous. According to the positioning mechanism of the deposit, the Origin type of the bauxite deposit is ancient weathering crust allochthonous bauxite deposit. On the basis of summarize the structure, stratum, rock, mineral, radioactivity and indicator for morphological ore - prospecting, the prospecting mechanism was built up. It＇ s thought that the surface exploration intensity in Wuchuan - Zhengan - Daozhen area is adequate. According to the regional exploration indicator and mechanism, and follow the principle of ＂unknown to known＂, the future task is predict and regard the deep exploration. It＇ s a important way to expand the forecast scaleof the regional bauxite deposit.
