Characteristic of the Distribution of Rare Gases and Preliminary Discussion of Thermal History in the Jilin

The concentration of cosmogenic and radiogenic rare gases in the Jilin present great variation. There are approximate linear correlation between cosmogenic ³He, 20, 21, ²²Ne and ³⁸Ar, and between radiogenic ⁴He and ⁴⁰Ar. There are approximate linear correlation between radiogenic ⁴He, ⁴⁰Ar and cosmogenic ⁶⁰Co as depth of the jilin meteorite, but there not linear correlation between radiogenic ⁴He, ⁴⁰Ar and cosmogenic ²¹Ne as depth scale of the Jilin parent body. These results have been shown that the distribution of concentration of ⁴He and ⁴⁰Ar in the Jilin meteorite is inhomogeneous, and it is irregular in the Jilin parent body, and that the concentration of ⁴He and ⁴⁰Ar increase toward from surfase to center in the Jilin meteoroid. We try to explanation unique characteristic of the distribution of ⁴He and ⁴⁰Ar concentration in the Jilin with impact effects between Jilin parent body and asteroids.
