摘　　要：在川西北马脑壳层控 Au- Sb- W建造矿床中 ,发现了辉锑矿的显微沉积层纹状组构。由细晶辉锑矿和自生石英交替互层所显示的方向与辉锑矿的粒内变形作用以及晶体粒度变化所显示的方向一致 ,也与矿石和围岩的宏观 -微观层理一致。The syngenetic fine laminated fabric of stibnite was recognized in the Manaoke stratabound Au W Sb deposit. The direction shown by the interbedded fine crystalline stibnite and authigenic quartz coincides with the direction shown by the intragranular deformation and change of grain size of stibnite. It is also in agreement with macroscopic and microscopic stratifications of ores and host rocks. This fabric is interpreted as a secondary fabric representing the relict predecessor fabrics of synsedimentary origin.
