摘要
对龙门山中段彭灌杂岩体中的一条韧性剪切带进行了确定和命名，并着重从显微组构及岩组学方面对其变形环境进行了讨论，推断其形成深度为１０ｋｍ、温度为５００℃、压力为５００ＭＰａ，形成时的差异应力值为８０～１１０ＭＰａ，应变速率为１０－１１～１０－１０ｍ／ｓ。
ne ductile shear zone in the Pengguan complex in the middle segment of Longmen Mountains is confirmed and named From microstructure and petrofabric analysis it is concluded that it was formed under conditions of temperature of 500℃,pressure of 500 MPa at depth of 10km with a stress difference varying from 80 to 110 MPa and a strain rate of 10-11～10-10m/s
