| 摘 要： | 鄂西北武当群变质岩中的绿泥石经成份分析确定为密绿泥石,但分属正光性和负光性。它们不仅具有不同的光学性质,而且具有不同的成份特点和不同的产状。它们虽然都形成于低温高压变质条件,但形成的温度有差别,负光性绿泥石比正光性绿泥石形成的温度要更低些。

| Abstract: | The chlorite in the metomorphic rocks of wudang Group in north-west Hubei province is classified into Pycnochlorife according to analysis. However, tnere are two sorts of chlorite which exhibits negative?and positive-optical characters, respectively, and have also different composition characteristics and occurences. Although both they were formed under the metamorphism conditions of low temperature and high perssure, the temperature for the formation of negative-optical chlorite is lower than that for the positive-optical one. |
