【摘要】：新疆博乐市喇嘛苏外围地区地表岩石风化剥蚀严重,直接找矿标志不明显,以大功率激电中梯测量为辅助功能的大比例尺岩石地球化学测量方法对发现和圈定隐伏矿体起到了重要作用。根据化探原生晕元素组合特点及空间分布特征,以单元素异常下限值和富集系数为划分标准,圈定了六个Ⅲ级化探异常带,异常评价初步认为Cu—Zn—Pb—Ag—W—Sn—Mn—As—Au—Bi多元素叠加异常的形成为找矿有利区,选元素共生组合特点较明显的异常带开展大功率激电工作进行化探异常的验证。在推断出的成矿有利部位布设钻孔并可见到矿体。
[Abstract]:The weathering and denudation of the surface rocks in the outer area of Lamasu, Bole City, Xinjiang, is serious, and the direct prospecting marks are not obvious. The method of large scale rock geochemistry survey with high power ionization ladder as auxiliary function has played an important role in the discovery and delineation of concealed orebodies. According to the characteristics of geochemical primary halo element assemblage and spatial distribution, the geochemistry method of large scale rock geochemistry has played an important role in the discovery and delineation of concealed orebodies. Based on the criterion of the lower limit value of single element anomaly and enrichment coefficient, six geochemical anomaly zones of grade 鈪，
