| 摘 要： | 本文描述了块金的形成新机制。在热液中呈金氢化物、金羰基化合物及纳料金粒子、纳米金合金粒子活化迁移。在表生条件下，金硫代硫酸盐配合物、金粒子、金合金粒子是金迁移的主要形式。块金是地质的、化学的、物理的、生物化学的综合作用的结果。按块金成因分为内生块金和次生块金。按单块块金质量分为４级。

| Abstract: | This paper treats on a new mechanism for the formation of scads. In hydrothermal solution, gold is activated and migrates in the form of hydride, carbonyl compound, nanometer particle, and nanometer alloy. Under supergene conditions, aurosulfate complex, gold particle and gold alloy particle are the major forms for the transportation of gold. Scads are the outgrowth of a complicated process involving geological, chemical, physical and biochemical factors. Based on genesis, two kinds of scads, i.e., the endogenetic scads and secondary scads are differentiated, and according to its mass, it is classified into four grades. |
