摘要
铬铁矿是我国工业建设中的短缺矿种。建国三十年来地质工作者在铬矿找矿上花费了不少的人力和财力，但距国家的需要还有较大的差距。出现这种结果笔者认为：前人在寻找铬矿过程中主要从超基性岩的岩石特征，镁铁比值和分异程度着手。
This paper deals with the factors affecting metallogenesis in ultrabasic rocks. It is concluded that there is a main factor which controls the occurrence of ore deposits, though many others may exist. It has been found that the abundance of chromium in ultrabasic rocks is a main index to distinguish metallogenic from non-metallogenic ultra-basic rocks. In this case the abundance values of chromium in metallogenic rock bodies are much higher than those in non-metallogenic ones. Therefore, in prospecting it is important to find out higher abundance values of chromium in ultrabasic rocks.
