青海南部三江北段莫云一东坝地区铀地球化学异常特征及其找矿潜力

青海南部莫云一东坝地区国土面积27 800kin ，圈出的铀元素异常面积达2 700km ，强度、规模均优于东昆仑已发现铀矿体的异常，其内已发现铀矿化线索，加快其解剖查证进程，对三江北段乃至全省铀矿资源勘查具有重要的现实意义。通过异常特征分析，优选出3处靶区，是主攻花岗岩型铀矿的重要目标域，应尽快安排下一步工作，同时对区内广泛发育的岩体与第三系、中侏罗统不整合面附近的可地浸砂岩型铀矿应予关注。

South Qinghai Three North of the Changjiang River Section not Cloud-east Dam Area Uranium Geochemical Anomaly Characteristic and Prospecting Potential

Qinghai southern part Moyun—Dongba alga covers 27 800 km，the uranium element abnormal area enclosed out amounts to 2 700 km ，the intensity and scale are equal better than that the uranium mine body's abnormal of the East Kunlun Mountains already discovered，the uranium minerization clue already was discovered in MoYun-DongBa，accelerating whose an atomy investigating and verifying acourse has important practical or immediate significance to the North of Three River，even the whole province's uranium mine resource prospecting．By the fact that the abnormal characteristic analysis，the text choice 3 gets that is important target region to study the granite type uranium mine，it should arrange next step working as soon as possible．The same time，the field soaks the sandstone type uranium mine should be paid closeing attention to the unconform ity face among rock masses and third departments developing．
