很早以前,乌拉尔就以发现巨大块金而驰名,但是,有关其成分、结构的报导以及能判断其成因的资料则极为少见。在斯莫林()所著一书中,对乌拉尔矿床块金的分布特征及产出条件进行了比较详细的研究。 彼得罗夫斯卡娅()对块金的总体性研究做出了重大贡献。在她的专著中系统整理了苏联各地(包括乌拉尔)的块金形态、表面刻蚀现象、成分和结构方面的资料;提出并论证了矿柱上部巨大块金的形成原理,认为是由于来自矿床深部的细分散金淋滤的结果。并认为块金的生长过程是长期的,而且是重复多次的。
Urals was well known for its discovery of huge gold blocks long ago, but information on its composition and structure, as well as information about its causes, is extremely rare. In Smolin’s book, the distributional characteristics and output conditions of gold in the Ural deposit are studied in more detail. Petrovskaia made a significant contribution to the study of the nuggets. In her monograph she systematically compiled information on the form of bulk gold, surface etching phenomena, composition and structure of various places in the Soviet Union (including the Urals), and proposed and demonstrated the formation principle of massive gold in the upper part of the pillar. Deep thin gold scattered leaching results. And that the nugget growth process is long-term, but also repeated many times.
