摘　　要：滇西无量山北段回龙山地区分布有大量的呈弧形分布的飞来峰构造。通过野外详细路线地质调查及室内的整理分析,结合先构造后地层的研究方法,重点对飞来峰的几何结构和变形特征进行了分析,确定了回龙山地区飞来峰群构造的存在,并提出逆冲推覆运动方向可能是自南西向北东推覆。There are many arcuate nappe structures on the region of Huilong Mountains in the northern margin of Wuliang Mountains of western Yunnan. Through detailed geological survey route of field and laboratory analysis, with the way that structural analysis before stratigraphic analysis, this article focused on the anatomical geometry and analysis of metamorphism and deformation characteristics about the nappe structure. It concluded that the nappe structures existed on the region of Huilong Mountains and they moved from the SW to the NE.
