| 摘 要： | 本文认为:化探数据的正态变换是正确估计背景、异常,清晰反映元素间相关关系的基础;R型因子分析是揭示元素相关结构进行成因分类的有效方法;多层次拟合、插值是表征矿化因子得分空间分布规律正确圈定找矿靶区的可靠依据。以此种技术措施对某区1:5万水系沉积物测量520km2的面积和土壤测量12km2面积的实际资料进行数据处理,获得大量有用信息,新发现矿化异常多处,深化了对控矿条件的认识,为进一步找矿指出了方向。

| Abstract: | The authors hold that the normal transformation of geochemical data is abasis for correct estimation of background and anomalies and clear manifesta-tion of correlation between various elements, that R-mode factor analysis seemsto be an effective method for revealing correlated structures of elements andmaking genetic classification and that the multilevel fitting and interpolationmake up reliable grounds for characterizing spatial distribution pattern ofmineralization factor scores. With such techniques, we performed processing ofdata obtained from 1:50, 000 stream sediment survey (covering520 km2) andsoil survey (12km2) in a certain district. As a result, large quantities of infor-mation were obtained, quite a few anomalies related to mineralizations disco-vered, and the knowledge of ore-controlling conditions deepened, thus pointingout the way for further ore prospecting. |
