| 摘 要： | 位于河南省西峡县北部地区的石界河群榴云片岩中的石榴石发育有很好的结构和成分环带。本文应用微分热力学方法对其环带成分进行计算,确定出一条顺时针方向的PTt轨迹。该轨迹与应用矿物共生组合世代关系确定的PTt轨迹十分吻合。

| Abstract: | A clockwise rotation PTt Path of the Shijiehe Group is derived from the zoned garnet by using the method of infinitesimal calculus thermodynamics. This method was proposed by Spear in 1991. The same PTt Path is also derived from the generations of mineral associations. It is suggested that the Shijiehe Group should be the uplist resulted in a part from tectonism. |
