摘要
随着我国工业经济的飞速发展,对各种矿产资源需求量日益增大,特别是国内优质钾长石、斜长石依赖进口。作为一名地质工作者在野外要快速、精准对钾长石、斜长石鉴定并按要求进行详细纪录如摄像、拍照、标注地理坐标等。本文通过对钾长石与斜长石,及其风化产物的特征对比,总结出在野外较精准鉴别钾长石类、斜长石类、石英的简单实用方法。
With the rapid development of China’s industrial economy, the domestic for a variety of mineral resources is increasing, but the high-quality potassium feldspar and plagioclase ores mainlyrely on imports. As a geological worker in the field to quickly and accurately identify potash feldspar, plagioclase, it is required that detailed records, relevant video, photography and geographic coordinates. In this paper, the basic characteristics of potassium feldspar and plagioclase are described simply and practically,such as weathering products characteristic comparison of the two ores. The accurate identification of potassium feldspar, plagioclase and quartz in the field is summarized.
