内蒙古敖兰敖日格一带侵入岩地球化学数据的统计分析与地质解释

STATISTICAL ANALYSIS AND GEOLOGICAL INTERPRETATION OF THE GEOCHEMICAL DATA OF THE INTRUSIVE ROCKS IN AOLANAORIGE AREA, INNER MONGOLIA

摘要: 采用数理统计方法，研究了内蒙古科右中旗敖兰敖日格一带出露的侵入岩的岩石地球化学特征.选用地质因子分析等统计方法，分析了解体后的敖兰敖日格岩体、杜尔基岩体中各侵入岩填图单位的常量元素、区域主要成矿元素等地球化学数据，总结了侵入岩的岩石地球化学特征由老到新的演化趋势及变化规律，探讨了各主要岩体与区域成矿的相关性，为区域地质找矿提供依据.

Abstract: The method of mathematical statistics is adopted to study the geochemical characteristics of the intrusive rocks in Aolanaorige area, Inner Mongolia. With geological factor statistical methods, the major elements, regional ore-forming elements and other geochemical data of the Aolanaorige rock body and Duerji rock body are analyzed after they have been disintegrated. The geochemical evolution trend and changing rule of the intrusive rocks are summarized, with discussion on the correlation between the rock mass and regional metallogenesis, which provide a basis for regional geological prospecting.
