集安石棉矿床,以往一直被认为属白云岩型蛇纹石石棉矿床。但该矿床的成因与国内外这类矿床迥然不同。典型的白云岩型蛇纹石石棉矿床的成因,都毫无例外的与中基性脉岩或酸性侵入体密切相关,受接触变质作用,为中温热液交代形成的石棉矿床。该矿床则是在区域变质作用的基础上进一步发展的结果,即区域混合岩化作用形成的。蛇纹石和石棉形成时的二氧化硅和结晶水来源于混合热液,氧化镁来自围岩(白云质大 Set of asbestos deposits, in the past has been considered as a dolomite serpentine asbestos deposit. However, the origin of the deposit is quite different from the deposits at home and abroad. The origin of the typical dolomite serpentinite asbestos deposit is closely related to the medium-basic vein rock or acid intrusive body without any exception and is affected by contact metamorphism and is an asbestos deposit formed by mesothermal hydrothermal. The deposit is the result of further development on the basis of regional metamorphism, that is, the formation of regional mixed lithification. Silica and water of crystallization during the formation of serpentine and asbestos are derived from mixed hydrothermal fluids and magnesia from surrounding rocks
