本文试图通过多元统计分析,即应用数学手段对我国西藏红区岩体西段的各岩相带岩石化学成份进行对比研究,特别是力图对其中的第 V 岩相带划分出含矿地段并作进一步评价。统计分析所使用的样品全部是1976年至1978年野外工作中采取的,由原地矿所八室及西藏地质局实验室分析。此外还搜集了西藏地质二队历年所取得的部分样品分析资料,除岩石化学样品外,还采取了若干造矿及附生铬尖晶石样品,对其化学成分亦进行了 Q 型点群分析。全部数据处理主要在地质部计算所和水文所 DJS-6机上进行的。工作过程中得到原地矿所四室数学地质组许多同志的指导和帮助,在此一并表示谢意。
In this paper, we try to use multivariate statistical analysis to compare the chemical composition of each lithofacies lithofacies in the western part of the rock mass of the Red Zone in our country with the help of mathematical methods. In particular, Further evaluation. All the samples used in the statistical analysis were taken from the field work from 1976 to 1978 and analyzed by the laboratory of the Institute of Earth and Ore and the Bureau of Earth Sciences of Tibet. In addition, some sample data obtained by Tibet’s Second Geological Survey team over the years were collected. In addition to petrochemical samples, several ore-forming and epigenic chrome spinel samples were also taken and their chemical compositions were also analyzed by Q-point cluster analysis . All data processing is carried out mainly on the Institute of Geology and Hydrology DJS-6. In the course of his work, he was gratefully acknowledged for his guidance and help from many comrades in the Geological Institute of Geology and Mineral Resources of the Fourth Institute of Geology and Mineral Resources.
