陨石的物理性质在陨石母体的演化过程中起到了重要作用。地球上的风化作用也会对陨石的一些物理性质造成显著影响。为了探讨风化对普通球粒陨石物理性质的影响,本文以库姆塔格普通球粒陨石为研究对象,使用密度仪、磁化率仪、热导仪、分光光度计等测量了其不同部位的物质性质,如颗粒密度,体积密度、孔隙度、磁化率、热导率、反射光谱强度等。研究结果表明:H型普通球粒陨石的颗粒密度、孔隙度、磁化率以及反射光谱强度会随着风化程度的加深而降低,而热导率和体密度受风化作用的影响相对较小。
The physical properties of meteorites play an important role in the evolution of meteorites. Weathering on Earth can also have a significant impact on some of the physical properties of meteorites. In order to study the effect of weathering on the physical properties of ordinary chondrites, this paper studied the ordinary chondrite meteorites in the Qomtagage. The density of materials, magnetic susceptibility, thermal conductivity and spectrophotometer were used to measure the physical properties of ordinary chondrites. Properties such as particle density, bulk density, porosity, magnetic susceptibility, thermal conductivity, reflectance spectrum intensity, and the like. The results show that the particle density, porosity, magnetic susceptibility and reflection spectrum intensity of H-type ordinary chondrites decrease with the degree of weathering, while the thermal conductivity and bulk density are less affected by weathering.
