The Laser microprobe analysis shows that the argon isotope is evenly distributed in the muscovite. The preliminary conclusion is (1) muscovite in high-pressure metamorphic orthogneiss does not contain excess argon and can be the object for 40Ar/39Ar dating;(2) muscovite in the Qinglongshan eclogite contains large amounts of excess ...

由此得出的初步结论是：①高压变质的正片麻岩中的白云母中不含过剩Ar，这类矿物可以作为~(40)Ar/~(39)Ar同位素测年的对象；②青龙山榴辉岩中的白云母含大量过剩氩，而作为其围岩的超高压正片麻岩中的白云母却不含过剩氩，这一事实证明了榴辉岩中白云母的过剩氩不是来自围岩，而是榴辉岩自身继承的。

By comprehensively using the information of lithostratigraphy, paleobiology, isotope, paleomagnetism, fission track of apatite, well-logging, geophysics and petroleum geology, the characteristics of the sedimentary wave processes in the Tazhong uplift, North depression and the Tabei uplift were studied by the wave process analysis method under the direction of the wave theory of the earth's crust movement in this paper, and the main achievements are as follows
