Tianjin Aeromagnetic Anomalies And Regularity

Aeromagnetic delineation as to distinguish between various types of magneticand geological body, dividing some mineralization prospective areas, geologicalstructure, directly or indirectly, to find deposits, as well as one of the main methods toprovide basic geophysical data for all sectors of the economy, since since theapplication was unanimously recognized by everyone. Based on a large-scalecomprehensive collection of Tianjin on aeromagnetic data, perform data compilationand detailed carried out various bit field conversion process, according to the latesttreatment outcomes, Tianjin aeromagnetic anomalies were classified contrast. Tianjin45aeromagnetic anomalies by category numbered, and each carried out a detailedaeromagnetic anomalies, accurate qualitative interpretation. Screening and solidmineral-related aeromagnetic anomalies5: Tianjin C1-1979-1(iron ore caused byabnormal), Tianjin C1-1979-2(iron ore caused by abnormal), Tianjin C1-1979-3(Zhuears unusual rock valley with phosphate-related), Tianjin C1-1979-5(winding rockanomalies, copper, tungsten, molybdenum related), Tianjin C1-1959-M71(mashenqiao rock anomalies, and phosphate-related). Through analysis of themagnetic field on the region of Tianjin, Tianjin magnetic field of the partition anddivision of tectonic units. Carved out a structural unit1, two tectonic units two, threetectonic units4.Elements within the scope of the secondary fracture Tianjin, rock, metamorphicformations, volcanic formations like the inference and interpretation, providing a richgeological background information. Total inferred break29, including a fracture four,two broken15, three breaking10; rock3, respectively, winding rock, rock and undermashenqiao warehouse rock; inferred volcanic strata12, metamorphic formations3.
