湘黔地区寒武纪黑色岩系中蕴藏着高含量的PGE,尤其是Pt和Pd两种元素,被称为是一种新型的铂族元素矿床类型,具有很大的资源潜力和科学意义,因而促使着国内外相关单位和科研人员不断地深入研究。然而黑色岩系中高含量的PGE以何种形式存在一直是研究的难点问题,目前还没有确切查明 The Cambrian black rock series in the Hunan-Guizhou area contain high levels of PGE, especially Pt and Pd, and are regarded as a new platinum group elemental deposit type with great potential and scientific significance. Thus prompting relevant units and researchers at home and abroad continue to conduct in-depth research. However, the existence of high levels of PGE in the black rock series has always been a difficult problem to be studied. At present, it has not been clearly identified
