中文摘要: |
旗鼓岭矿区位于阳春盆地的南缘,为近年取得初步突破的矿区,但矿区具体的化探异常和找矿方向研究程度较浅。为研究旗鼓岭矿区土壤地球化学特征,指导进一步找矿,对该矿区进行了1∶10000土壤地球化学测量,选取了阳春盆地与Cu、W、Mo成矿关系密切的11种元素进行测试,在对数据和相关参数进行分析后认为Cu、W、Pb元素分异性强、集散性明显、相关性好可以作为矿区的找矿标识。矿区元素次生晕异常分带明显,Cu、W、Bi、Mo等中高温成矿元素主要分布在矿区北段旗鼓岭附近,Au、Ag等中低温成矿元素主要分布在外围。因此,根据成矿地质条件和元素的异常分布特征,在旗鼓岭矿区圈定出7处综合异常,且经揭露找矿效果良好。综合重磁化等方法异常信息指出矿区中部为进一步勘查的首选区段,为下一步矿区勘查提供了找矿方向。 |
英文摘要: |
The Qiguling Mining Area is located in the southern margin of Yangchun Basin, which has a preliminary breakthroughs in recent years. However, the specific geochemical anomalies and prospecting direction of the mining area are not well studied. In order to study the soil geochemical characteristics of Qiguling Mining Area and guide further prospecting, a 1∶10000 soil geochemical survey was carried out in the mining area, and 11 elements closely related to Cu, W and Mo mineralization in Yangchun Basin were selected for testing. After analyzing the data and related parameters, it is concluded that Cu, W and Pb elements can be used as prospecting identification of mining area with strong differentiation, obvious distribution and good correlation. The abnormal zonation of secondary halos is obvious in the mining area. For example, Cu, W, Bi, Mo and other medium-high temperature ore-forming elements are mainly distributed near Qiguling in the northern section of the mining area, while Au, Ag and other medium-low temperature ore-forming elements are mainly distributed in the periphery. Therefore, according to the metallogenic geological conditions and the abnormal distribution characteristics of elements, 7 comprehensive anomalies have been delineated in Qiguling mining area, and the engineering exposure shows that the prospecting potential is good. Finally, based on the anomaly information of remagnetization and other geophysical and chemical exploration, it is pointed out that the central part of the mining area is the first choice for further exploration, and the next exploration direction of the mining area is indicated. |
