胶东半岛海阳地区水系沉积物地球化学特征及找矿方向

Geochemical Characteristics of Stream Sediments and Oreprospecting Direction in Haiyang Area in Jiaodong Peninsula

摘要:

在胶东半岛海阳地区万第幅、朱吴幅、乳山寨幅、行村幅、海阳县幅、留格庄幅6幅1∶5万水系沉积物测量的基础上，对该区的地球化学特征进行了初步分析。对元素丰度特征、富集与离散特征、元素在不同地层单元中的特征值、元素组合特征进行了研究，发现Au，Ag，Cu，Pb为区内具有一定潜力的找矿指标。根据地质成矿条件及综合异常分布情况，划分了5处成矿远景区：分别为八夼小疃地区Au成矿远景区；小纪镇地区Cu，Au及多金属成矿远景区；大黄家地区Pb，Zn，Cu成矿远景区；留格庄地区Au，Cu，Pb，Zn多金属成矿远景区；盘石店镇地区Pb，Mo成矿远景区为下一步找矿指明了方向。

Abstract:

On the basis of stream sediment survey in Wandi, Zhuwu, Rushanzhai, Xingcun, Haiyang, Liugezhuang with the scale of 1∶50000 in Haiyang area of southwestern Jiaodong peninsula，geochemical characteristics of this area has been analyzed primarily. Characteristics of element abundance, enrichment and dispersion characteristics, characteristic value of elements at different stratigraphic units and combination characteristics have been studied. It is found that Au, Ag, Cu, Pb are prospecting indicators with certain potential in this area. At the same time, according to geological metallogenic conditions and comprehensive anomaly distribution, five metallogenic prospect areas have been divided, they are Bakuang Xiaotuan Au metallogenic prospecting area, Cu，Xiaojizhen Au and polymetallic metallogenic prospecting area, Dahuang jia Pb，Zn，Cu metallogenic prospecting area, Liugezhuang Au，Cu，Pb，Zn polymetallic metallogenic prospecting area, Panshidian Pb，Mo metallogenic prospecting area. It will point out the direction for ore prospecting in this area in the future.
