摘要
横江韧性剪切带与金矿关系密切。该带中央为揉流褶皱带,往两侧至边缘依次出现鞘褶皱、a型褶皱、b型褶皱。带内发育的拉伸线理方向与剪切带走向近于垂直,旋转石香肠指示剪切运动方向为北西一南东向右型剪切,表明本带为韧性推覆剪切带。
There is colse relation between Hengjiang ductile shear zone and Au-deposit. The mid-belt form flowage fold, from the mid-belt to margin belt, the structural types are successively sheath fold; A-fold; B-fold. Srike of stretch linears in belt near perpendicular to shear zone. Indicational shear movement di-mension by rotated boudinage structure is NW-SE, dextral. It is a ductile nappe shear zone.
