利用特定的40 Ar/ 3 9Ar阶段加热程序和MDD模式处理得到的钾长石冷却曲线 ,加之角闪石、黑云母和磷灰石的年龄测定结果 ,进一步研究了冈底斯岩带结晶后热演化史的特征 ,对比了该岩带东、西两部分快速冷却起始时间和磷灰石FT(裂变径迹 )年龄变化的规律性 ,给出了印度与欧亚板块碰撞后岩石圈质量转移能量传递过程的佐证 .
Based on the results of age determination of amphibole, biotite and apatite by using the specific 40 Ar / 3 9Ar stage heating process and the KD feldspar cooling curve obtained from the MDD process, the post-crystallization heat of the Gangdese zone was further studied Evolution history, the regularity of the onset of rapid cooling and the age of apatite FT (fission track) in the eastern and western parts of the belt are contrasted. The lithospheric mass transfer after the collision between India and Eurasia Evidence of energy transfer process.
