| 摘 要： | 从地层单元和岩石类型两个方面系统地讨论了滹沱群下部成矿元素的地球化学特征 ,包括元素的均值、众数值、浓集系数、变异系数以及元素之间的聚类组合特征。滹沱群内的金矿化明显受岩性和地层控制 ,即金矿化不超过下部层位的三个组并主要赋存于四集庄组地层中 ,陆源粗碎屑岩组合是主要的金释放岩石。滹沱群下部具有明显的变质砾岩型金矿化潜力 ,在合适的条件下 (围岩、构造、变质变形、岩浆作用等 )会产生与变质砾岩型金矿化有密切成因联系的沉积变质热液叠加或次火山热液叠加型金矿化 |

| Abstract: | This paper, in the terms of stratigraphic unit and rock association, has discussed the geochemical characteristics of ore-forming elements in the lower part of Hutuo group, including the average value, modal value, enrichment coefficient, variation coefficient, and element-cluster analyses. It is reasonable to assume that gold mineralization in Hutuo group is obviously controlled by both rock association and stratigraphic units, strictly limited within the 3 formations of lower Hutuo group, particularly in Sijizhuang formation with the coarse clastic rock association as the main gold-releasing rocks. Synthetic analyses indicate that the lower Hutuo group remarkably has the potential to develop gold-mineralized type of metaconglomerate, and in appropriate conditions(wall rock, structure,metamorphism and deformation, and magmatism etc. ),may develop metaconglomerate-based mineralized types superimposed or remobilized by metamorphic or subvolcanic hydrothermal solutions which have close genetic relationships with gold-mineralized type of metaconglomerate. |
| Keywords: | lower Hutuo group ore-forming elements geochemical characteristics gold mineralization |
