摘要 首次根据浙江省西北部荷塘组岩石样品的实测数据,提出了浙江省荷塘组黑色岩系6个岩性层的Pt、Pd、Au、Ag、Cu、As、Sb、Pb、Mo、Ni、V、P、U、B、Cd、Tl、Se、Zn元素的平均值,运用微量元素和稀土元素的配分模式探讨了成岩环境及元素高含量对环境的影响。荷塘组富集元素较多,富集程度高的有Mo、Se、Cd、Ag、Sb、U、As、P;较富集的有V、B、Cu、Tl、Zn,弱富集的为Au、Pt、Pb、Ni。综合地质地球化学特征研究认为,荷塘组黑色岩系具有寻找含钼、磷、矾和有色金属矿产的潜力。
Abstract :〖WT5”BZ〗Based on measured data of rock samples from Hetang Formation in northwest Zhejiang Province, this paper gave
the average values of such elements as Pt, Pd, Au, Ag, Cu, As, Sb, Pb, Mo, Ni, V, P, U, B, Cd, Tl, Se and Zn in the black shales of
Hetang Formation, and dealt with the rockforming environment and the influence of high element contents on the environment
according to the partitioning models of trace elements and rare earth elements. The Hetang Formation is enriched with quite a lot of
elements: abundant Mo, Se, Cd, Ag, Sb, U, As and P, subordinate V, B, Cu, Tl and Zn, and small amounts of Au, Pt, Pb and Ni. An
integrated geological and geochemical study has revealed that there exists oreprospecting potential for Mo, P, V and nonferrous
metals in black shales of the Hetang Formation.
