The results show that the thermo-luminescence of quartz sandstone decreases with the increase of impact pressure, and there exists an external shock zone at the impact site Thermoluminescence gradient, the same position of induced thermoluminescence also exists a thermoluminescence gradient. Xinyang meteorite samples were impacted at pressures of 12.4, 28.9, 37.8, 51.8, 64.6 and 77.6 GPa respectively, and the fission track density and length were measured before and after impact. The results show that the fission track density and length of Xinyang meteorite become smaller and shorter as the impact pressure increases.
