苏丹北部红海州16区块地质特征及找矿方法探讨

摘要

No.16 block locates in Red Sea State in northern Sudan.1 1 gold occurrences and 6 copper occurrences have been found in this area,4 prospective metallogenetic areas have been selected,and one mini type gold deposit has been evaluated as well.Geological conditions,mineralization characteristics and types of No.16 block have been introduced in this article.Setting the already evaluated small type gold deposit as an example,metallization and controlled factors in this area have been discussed.It is pointed out that there is a good future of gold and cop-per mineralization.Pointing to factual condition in this area,it is regarded that remote sensing information explai-ning associated with geochemical and geophysical survey are the effective methods for selecting exploration target ar-eas,while trenches in the ground surface associate with drilling holes control in middle and deep parts are necessa-ry exploration method.%16区块位于苏丹北部红海州，区内已发现金矿点11处，铜矿点6处，优选出了4个成矿远景区，评价了小型金矿床1处。该文介绍了16区的成矿地质条件、矿化特征及矿化类型，以已评价的小型金矿床为例讨论了该区金矿成矿作用及控矿因素，指出该区具备良好的金铜矿成矿远景。针对该区实际情况提出遥感解译配合化探测量、物探测量是选勘查靶区的有效方法，地表槽探揭露配合中深部钻探控制是必要的勘查手段。
