摘要
赫尔辛基铬铁矿位于全球著名的铬铁矿和铂族金属成矿带———布什维尔德杂岩体的西翼,成矿地质条件优越。通过整理研究赫尔辛基铬铁矿以往历史资料,结合区域上铬铁矿成矿规律,对该铬铁矿床地质特征及成因进行了分析和总结,旨在为中国企业海外并购,或在矿区及周边的找矿工作提供参考。研究表明,矿体主要产出在铬铁矿层中,其产状和厚度稳定,围岩主要为辉石岩、斜长岩和苏长岩等基性—超基性岩,属典型的层状铬铁矿床;矿石质量好,资源储量巨大,且易于开采,矿床经济价值显著。
Helsinki chromite deposit is located in the world famous chromite and platinum-group metal metallogenic belt—the western limb of Bushveld complex.According to analyze the previous data of Helsinki chromite deposit,combining with the metallogen⁃ic regularities of the regional chromite deposits,this paper summarizes the Geological characteristics and genesis of Helsinki chromite deposit.In order to provide reference for the overseas merger and acquisition of Chinese enterprises,or provide reference for the pros⁃pecting and exploration work in the deposit.The study shows that the ore body is mainly produced in the chromite layer,and its occur⁃rence and thickness are stable.The surrounding rock are mainly pyroxene,anorthosite and cyatholite and other basic-ultrabasic rocks.The chromite ore’s quality is good,the ore resource is huge,and it is easy to exploit,so the economic value of the deposit is remarka⁃ble.
