Abstract: Rock is the most important material of the earth, and the structure and dynamic properties of the earth are bound to be closely related to the physical properties of rocks, so the petrophysical property data is also the basic data of geophysical exploration. In geophysical exploration, the comprehensive analysis of density, susceptibility, resistivity and polarizability parameters is commonly used in gravity, magnetic measurement and electrical measurement, which can assist in explaining the origin of geophysical anomalies and thus gain a deeper understanding of related metallogenic geological problems. Through the comprehensive analysis of drilling rock in Xinjiang northern Kubusu erea, we roughly defined the region within the weak magnetic anomaly genesis and infers the deep strata interface, clear the mineralization potential and provide the basis for the next step work.
