摘要
通过对新疆比勒提地区1∶50000水系沉积物测量Cu、Pb、B、Ti元素进行多重分形分析,划分出两类多重分形特征模式,即多重分形幂律图可用2段直线来拟合的模式一和可用3段直线拟合的模式二。模式一中元素可分解为背景与区域异常2个部分,无明显富集,不具成矿潜力;模式二元素除了具有模式一的背景与区域异常外,还发育较强的局部异常,在局部异常处,有较大的找矿潜力。通过对该区地球化学和地质特征分析,圈定靶区4处,为寻找Cu、Pb多金属矿产提供了依据。
Two types of multifractal modes are generalized from Cu, Pb, B, Ti in 1 ： 50000 stream sediment survey in Bileti area of Xinjiang. The power-law diagram of mode one and mode two are fitted by two straight lines and three straight hnes respectively. El- ements of mode one are distributed as background and regional anomalies, which show no significant enrichment and ore-forming potential. Elements of mode two have strong local anomalies with fairly promising prospecting potential in addition to the background and regional anomalies. Four prospecting targets for Cu, Pb polymetallic minerals are delineated based on geochemical and geological characteristics in this area.
