    摘要:

    在韧性剪切带与金矿床之间密切的空间关系业已得到公认,但在形成时间和成因关系以及物质来源诸问题上则争论颇大。本文剖析了目前研究中所存在的若干问题和混乱缘由,进而认为:韧性剪切带中既可存在韧性剪切期韧性剪切带型金矿化,又可存在韧性剪切期后蚀变破碎带型金矿化;既可有深部成矿物质来源,又可有浅部表层成矿物质来源,实际上为典型的多因复成金矿床。因此建议将其称之为“与韧性剪切带有关的金矿床”。

    Abstract:

    It has been recognized that there exists close spatial relationship between ductile shear zones and gold deposits, but there is still a much controversy over some problems such as their temporal and genetic relationships and source of ore-forming material and fluids. This paper analyses some problems and confusions existing in the present study. It holds that gold deposits hosted in ductile shear zones may have both syn-ductile shearing ductile shear zone-type and post-ductile shearing altered fracture zone-type gold mineralization and may have both deep-seated soruces of ore-forming material and shallow or superficial sources. Actually they are typical polygenetic compound gold deposits. Therefore the authors suggest that these gold deposits are called "gold deposits related to ductile shear zones".
