胶东地区前孙家-洼孙家断裂南段构造控矿规律及找矿研究
|
摘要
胶东西北部是我国重要的金矿聚集区,矿床主要受断裂构造控制。前孙家-洼孙家断裂是研究区内主要控矿断裂。依据该构造南段前孙家、金华山两个金矿的岩石、构造、矿体分布、矿化蚀变等特征,对两矿区的构造控矿型式、构造控矿规律进行了探讨,认为该区成矿热液活动具有多期性。成矿预测表明前孙家矿区4号脉的深部可能存在盲矿体,2号脉在深部有一定的延伸;金华山矿区1号脉的下盘可能存在与1号脉平行的雁列脉矿体; 1号脉、2号脉在深部应有交汇,可作为重点找矿位置。
The northwestern part of the Shandong Peninsula is a major area of gold ores gathered,mainly controlled by faulted structures. The Qiansunjia-Wasunjia fault is the main ore controlling fault in the study area. Based on lithological,structural,orebody distribution and metallizing alteration features of Qiansunjia and Jinhuashan two gold ores in the fault southern sector have carried out discussion on structural ore controlling pattern and regularity,considered that the ore-forming hydrothermal activities in the area are multiphasic. The ore-forming prediction of the deep part vein No. 4 in Qiansunjia ore district deemed that blind orebodies possibly existed,the vein No. 2 may have certain deep part extension; heading side of the vein No. 1 in Jinhuashan ore district may have en echelon orebodies parallel to vein No. 1,while vein No. 1 and No. 2 should be intersected in deep part,thus can be the key prospecting target.
