| 中文摘要: |
| 近年来,国内外利用岩株中黑云母成分,特别是氟和氯等卤素成分的研究,作为岩体是否含矿的标志方面做了大量的工作,并在斑岩型铜矿床的找矿评价中有一定成效.但是,也有一些不含矿的岩株的黑云母中,亦含有较高的氟和氯,还有待于深入研究.在一些地区,含铜矿化的斑岩侵入体中的黑云母,含氟、氯和铜等元素显著偏高.因而,我们就可以利用这些元素的含量和成分变化特征作为找矿标志,对扩大斑岩型矿床的找矿远景,加速矿床的评价有重要的现实意义. |

| It is of great significance using variation features of halogen in biotite from intrusions as mineralization guide, especially for porphyry copper deposits. The alogen content in biotite from mineralized intrusions is higer than that of barren strocks.Except for halogen and discontinuity of Fe Mg and Ti contents can’also provide guidelines for determining the favourability of intrusives. Along biotite crystal traverses, the increases in Mg/Mg + ΣFe and the decreases of TiO2 towards the rims represent the characteristics of mineralized stocks. It is evident that using multivariate analysis for discriminating between mineralized and barren stocks might lead to reliable results |
