索科洛夫專家在报告中首先提出了新的苏联铁矿成因分类:火成矿床、外生矿床、变質矿床。在火成矿床中,將接触交代矿床分成三个亚类:(1) 方柱石矿床;(2)矽卡岩矿床;(3) 水矽酸鹽矿床。他並指出了接触交代型铁矿分佈規律控制因素:道先是侵入体,只有基性或鹼性较高的类花崗岩,如闪长岩、石英闪长岩、鹼性花岗岩、正长岩、二长岩才能形成接触式铁矿床。侵入体的深度是中深时对成矿有利,就是說,具斑状结构的鹼性花崗岩对成矿最有利。圍岩成分若为火山岩、凝灰岩、凝灰沉积岩、玢岩並含有灰岩透鏡者,則有利於成矿。他还谈到西伯利亚与暗色岩有关的巨大的热液鎂磁铁矿床,它局限在古火
In his report, Sokolov experts first proposed the new genesis of the Soviet iron ore: the fire-hosted deposits, exogenous deposits, metamorphic deposits. In the metamorphic ore deposits, the contact metasedimentary subdivisions are divided into three sub-categories: (1) barite deposit; (2) skarn deposit; (3) aquiferous silicate deposit. He also pointed out that the controlling factors of the distribution of contact metasedimentary iron ore are as follows: The Tao is intrusive with only basic or high alkaline granitoids such as diorite, quartz diorite, basic granite, syenite, Feldspar can form a contact iron deposit. The depth of intrusions is favorable for metallogenesis when the depth is in the middle, that is to say, the alkaline granite with the porphyritic structure is the most favorable for metallogenesis. If the wall rock composition of volcanic rocks, tuff, tuff sedimentary rock, rock and limestone lenses, it is conducive to metallogenesis. He also talked about the huge hydrothermal magnesium magnetite deposit associated with dark-colored rocks in Siberia, which is confined to ancient fire
