钛铁矿在金伯利岩中为金刚石的董要伴生矿物之一,它在非洲及苏联雅库特地区金伯利省印广泛分布,成为寻找金刚石原生矿的主要标志矿物。在我国金伯利岩中由于钦铁矿含量较少,对其研究也不够深入。两年多来笔者对我国金伯利岩中的钦铁矿进行了一些研究,取得了一些初步的结果,现综述如下。一、产状我国金伯利岩 Ilmenite is one of the most important minerals associated with diamond in the kimberlite. It is widely distributed in Africa and the Kimberley Province in the Yakutia region of the Soviet Union and has become the major mineral of interest in searching for primary diamond deposits. In our kimberlite rock due to less content of gold, its research is not deep enough. For more than two years, the author has made some researches on the porphyry in China’s kimberlite, and has made some preliminary results, which are summarized as follows. First, the occurrence of kimberlite in China
