摘　　要：板昌逆冲推覆构造带不仅是对黔西南地区表层地壳变形具有重要影响的构造边界,而且对烂泥沟特大型金矿床、百地金矿床、尾排金矿床、岩架金矿床等卡林型金矿床的形成与分布具有重要控制作用。以区域构造成矿学理论为指导,在板昌逆冲推覆构造带近年探矿新资料及新成果的基础上,系统论述该构造带的物质组成和变形特征,讨论该构造带的形成演化对卡林型金矿成矿的控制作用,目的在于继续深入研究黔西南地区构造特征与金矿成矿规律,为大区域成矿作用和成矿规律研究提供基础资料,实现区域找矿取得突破提供新的思路及科学依据。Banehang thrust nappe structure zone is not only an important structural boundary for surface erustal deformation in Southwest Guizhou, but also has greatly shaped the genesis and distribution of sueh earlin type deposits as Lannigou Gold Deposit, Baidi Gold Deposit, Weipai Gold Deposit and Yanjia Gold Deposit. Regional tectonic metallogeny systematically described composition and deformation features of the tectonic belt and discussed shaping effects that the tectonic belt has on the mineralization of these carlin type deposits based on fresh data and achievements made possible in recent years＇ exploration on Banchang thrust nappe tectonic belt. Its purposes are to further examine the structural eharaeteristies and mineralization regularities in this area, offer fundamental data for superordinate research and ideas and scientific bases for breakthroughs in regional prospeeting.
