| 摘 要： | 攀西地区是我国重要的铂族元素地球化学省,具良好的铂族元素(PGE)成矿地质条件;攀枝花-西昌一带有一个与峨眉山玄武岩分布范围基本吻合的Pt、Pd区域地球化学异常。本文根据不同地层单元水系沉积物中Pt、Pd元素地球化学特征,用子区中位数衬值滤波(SAMCF)法提取铂族元素异常,圈出多处Pt、Pd衬值异常区。结合有关铂族元素矿床地球化学特征,通过水系沉积物中Pt、Pd综合异常的筛选,初步优选出8个铂族元素异常找矿远景区和19个Ⅱ类异常区,为进一步开展铂族矿床找矿提供依据。 |
| 关 键 词： | 攀西地区 铂族元素 子区中位数衬值滤波法(SAMCF) 地球化学异常 异常提取 |

| Abstract: | The Panzhihua-Xichang area is located in an important PGE geochemical province in China with good PGE ore-forming geological condition.A regional Pt-Pd geochemical anomaly is basically in accordance with the distribution of the Emeishan basalt in the Panzhihua-Xichang area.Based on the Pt and Pd geochemical features of the stream sediments from various stratum units in this area,many PGE anomalies have been outlined by using the subregion median contrast filtering method (SAMCF).In the combination of the characteristics of the PGE deposit geochemistry,8 prospective anomalies and 19 second class anomalies have been selected from those PGE anomalies of the stream sediments for further prospecting of PGE mineralization in the area. |
| Keywords: | the Panzhihua-Xichang area PGE elements subregion median contrast filtering method(SAMCF) geochemical anomaly anomaly extracting |
