摘    要:The Mianl黣 tectonic zone has been recently identified as an ophiolitic tectonic m閘ange zone on the southern margin of the Qinling Belt1—6]. The m?lange zone, stretching from east to west in the Mianxian-Lueyang region, represents a newly recog-nized Mianl黣 ophiolitic complex which is quite dif-ferent from the Shangdan ophiolite cropping out in the area between the North and South Qinling in terms of age and composition1—6].
