河南省光山县千鹅冲钼矿岩石地球化学特征及其意义

In henan province,the guangshan county thousand goose impact molybdenum ore rock geochemical characteristics and significance

通过对矿区内地层、岩浆岩、变质岩、构造岩四大岩类1255件样品,8种元素算术平均含量(X)、变异系数(CV)、浓集克拉克值(Kk)和衬度(P)的分布、分配特征分析对比,来确定矿区背景值(C0)及矿物质来源。为尽可能避免强矿化的影响,采用了统计法,迭次剔除≥+2.5S的数据。

through the mainland of mining area layer, magmatic rock, metamorphic rock, tectonic rock four big rock class 1255 samples, 8 kinds of element arithmetic average content （X）, coefficient of variation （CV）, concentration Clarke （Kit） and contrast （P） distribution, distribution characteristics analysis contrast, to determine the mining background value （CO） and mineral sources. For as far as possible to avoid the influence of strong mineralization, the statistics, again and again to eliminate or ＋ 2.5 S data.
