福建及邻区的区域地球化学异常成因分类与地球化学找矿问题

On the Genetic Classification of Regional Ggeochemical Anomaly in Fujian Province and Its Neighbour Areas and Some Geochemical Ore-finding Problems

据 1∶ 2 0万区域水系沉积物地球化学成果资料 ,以地球化学元素与元素组合同具有一定规模地质体之间的空间与内在关系为准则 ,将 30多种元素分为两个大类 ,继而对元素或元素组合的异常划分为不同成因类型 ,评定它们在研究区域地质与找矿中的实际意义。结合福建矿产勘查历史 ,探讨地球化学找矿中的几个问题及其经验。

Based on the geochemical data of regional drainage sediments(scale 1∶200 000)and the spacial and internal relations among the geochemical elements,element assemblages and the definite dimension of geological bodies,about 30 elements were grouped into two kinds:genetic classification of anomalies and geological classification of elements,and the element anomaly and element assemblage anomaly were divided into different genetic types.In the paper the authors also made a discussion of their significance in the regional geology and the ore finding research and of some problems about geochemical ore finding.
