珠穆朗玛峰顶部岩石标本地质年代的多元判别分析

1960年5月25日中国登山队由珠穆朗玛峰(以下简称“珠峰”)顶部采得的结晶石灰岩标本,确定它们的地质年代对于了解喜马拉雅区域地质是十分有意义的。我们仅得到一小块标本,采集于珠峰顶部“钙质岩系”的残留部分。

STUDY ON THE GEOCHRONOLOGY BY THE MULTIVARIATE DISCRIMINANT ANALYSIS

To a piece of rock collected from the Mount Jolmo Lungma Region in Southern Tibet of China, the geochronology is discussed by the multivariate discriminant analysis. On the basis of data obtained from calculation of the chemical composition of the rock, using the 109-Ⅱ computer the geological age of the sample is determined as Paleozoic, i.e. Cambrian-Ordovician period or approximately Ordovician period.
