为探究与基性—超基性岩有关的铬铁矿床所体现的重砂矿物类型及其组合特征，在西藏、新疆、甘肃、青海、内蒙古、河北和陕西7个省（自治区）共选择14个典型铬铁矿床（点），对所响应的自然重砂矿物进行统计。研究表明，这些矿床（点）中所响应的矿物主要为铬铁矿及铬尖晶石，计算出所涉及重砂矿物的报出频数及报出率，并通过图解直观地表现出与基性—超基性岩有关的铬铁矿床的自然重砂矿物组合，为与基性—超基性岩有关的铬铁矿找矿勘查提供了重要的矿物学依据。

This paper aims to explore types of heavy minerals related to basic-ultrabasic rock chromite deposits and their combina?tion characteristics in Tibet, Xinjiang, Gansu, Qinghai, Inner Mongolia, Hebei and Shaanxi. 14 typical chromite deposits were select?ed to study the natural response of heavy minerals. It is found that the responding minerals in these deposits are mainly chromite and chromium spinel. In addition, the authors calculated the frequencies of occurrence of heavy minerals involved and displayed the natu?ral heavy mineral assemblages in chromite deposits related to basic-ultrabasic rocks audio-visually through illustrations, thus provid?ing important mineralogical reference data for the exploration of chromite deposits.
