Abstract Geophysical and geochemical exploration in Taishanmiao area of Xixiang district within southern Shaanxi is characterized by low work extent, single exploration method and very insufficient anomaly information. In order to investigate the distribution, extensional boundary and deep variation of the magnetite deposit in the basic rock mass, the author adopted ground high-precision magnetic method and utilized such methods as upward continuation and 2.5D human-computer interactive inversion in conjunction with 1:25 000 stream sediment survey results and geological characteristics to make interpretation and deduction of anomalies. Through careful processing of data obtained from ground high-precision magnetic survey, the author delineated the range of magnetic anomaly, determined the distribution and spatial characteristics of magnetite deposit in the basic rock mass, thus providing the verifiable target for further deployment of geological exploration work.
