青海省北部绿草山地区化探元素组合分类信息探讨

Discussion on Geochemical Elements Classifing Information in Lvcaoshan Mountain in North of Qinghai Province

摘要:

对化探元素组合分类信息的研究可以为下一步的化探异常查证及成矿预测有很大的帮助。该文利用因子分析法对大柴旦行委绿草山地区23个元素、6026件样品的化探分析测试数据进行了元素的组合分类信息探讨。结果表明，因子得分图可以是分类元素组浅表地球化学场的一种反映，高低异常突变区域可能为不同性质地球化学场界面或者作为构造线的反映，处于构造部位的局部低缓异常区也应在化探异常查证工作中引起重视。

Abstract:

Study on classified information of geochemical elements combinations can be helpful for the next geochemical anomaly checking and metallogenic predication. In this paper, by using factor analysis method, geochemical data of 23 elements and 6026 samples in Lvcaoshan area have been classfied and studied. It is showed that, factor score graph can be a reflection of shallow geochemical field of classification elements combinations. High and low level abnormal regions may be different geochemical field interface or as a reflection of tectonic line. Regional slow abnoraml areas in strucutral sections should be paid more attention in the verification work of geochemical anomalies.
