Abstract
Qinghai Province is the second largest meteorolites falling area in China. The samples are provided by Tianshi Cultural Development Co., Ltd., and are numbered HYLYS-1, THYS-2, HTYS-3 and SMDYS-4, and the results of density test is 7.57g / cm3, 3.60 / cm3, 3.80/cm3 and 3.19 / cm3 respectively. Major elements include Al, Ti, Ni, Mg, Ca, Fe, K, etc. Trace elements include Co, Ba, Te, Cd, Ce, Li, La, Nd, Sr, etc. The results of testing shows that the resistivity of HYLYS-1, HTYS-3 is low, which indicates that there are many metal minerals such as iron and nickel, and the resistivity of THYS-2, SMDYS-4 is high, which indicates that there are few metal minerals. From the analysis of the chemical elements of the samples, resistivity is positively correlated with the contents of nickel and iron, and has good fitting degree. The main factors that affect the resistivity of the samples include meteorite structure, moisture content, mineral crystal, ambient temperature, porosity and so on. To study the resistivity characteristics of Qinghai meteorolites is an effective means to obtain the key information about the physical characteristics, structure, chemical components, the state of occurrence of metallic elements, mineral crystals and its arrangement, etc.
