| 中文摘要: |
| 基性-超基性岩中赋存有铜镍硫化物矿床、豆荚状铬铁矿床等许多重要的矿床,基性-超基性岩成岩成矿方面的研究多采用镁铁比值,但以往利用该比值时未考虑岩石的SiO2含量、地质构造及岩石蚀变等一些重要条件。文章结合国内外一些重要的铜镍矿床和铬铁矿矿床,考虑到上述的几个条件,讨论了镁铁比值在划分岩石类型方面的应用,通过计算给出了与前人不同的镁铁比值划分区间。 |
| 英文摘要: |
| There are many important ore deposits hosted in the basic-ultrabasic rocks, such as Cu-Ni sulphide deposits and podiform chromite deposits. Researches on petrogenisis and metallogenisis of basic-ultrabasic rocks applied generally the Mg/Fe ratio and ignored some crucial conditions such as SiO2 content, geological structure and rock alteration. In consideration of some important Cu-Ni deposits and chromite deposits at home and abroad and above conditions, this paper discussed the application of M/F in the rock classification and proposed new division fields based on calculation. |
