| 中文摘要: |
| 青海省有色地质矿产勘查院通过多年的工作,在占卜扎勒地区发现两条磁异常(I、Ⅱ),在I号磁异常内圈定了3处矿致异常(M1、M2、M3),地表共圈出铁矿体12条；占卜扎勒铁矿主要产于华力西期的二长花岗岩和金水口群白沙河岩组的大理岩接触带内,矿体呈似层状、不规则脉状、透镜状,有分支、复合尖灭再现的特点；总结和分析了该区地层、构造、岩浆岩与成矿的关系,根据异常的地质特征和矿体特征,矿床类型初步定为夕卡岩型铁矿,通过和邻区野马泉铁矿的对比,分析了占卜扎勒铁矿找矿前景。 |
| 英文摘要: |
| Through the years of work in the area of Zhanbuzhale, it is found two magnetic anomaly ( I, II )by the Nonferrous Geological Ore Prospecting Institute in Qinghai Province .There are three magnetic anomaly ( M1, M2, M3)in the I magnetic anomaly,which are mine induced abnormal, and total 12 iron ore has been found in the area, the Zhanbuzhale iron ore produced mainly in the contact zone.Between the two long granite of Hualixi period and the marble of Jinshuikou port's Baishahe rock group, the ore body lenticular or irregular has the characteristic of branching, composite, pinchout and reproduction. According to the geological characteristics and the ore body characteristics, a skarn type iron ore has been set, the relationship of mineralization in the strata,magmatic is summarized and analyzed. Through the comparison with the Yemaquan iron ore in adjacent areas, the prospects of Zhanbuzhale iron ore is summed up. |
