Abstract

In order to study the features of geophysical field and deep structure of the eastern part of Junggar basin, we collected gravity and magnetic data with a scale of 1:1,000,000. Then, we calculated the isostatic gravity anomaly based on the Bouguer gravity anomaly data and the aeromagnetic anomaly by reduction to the pole (RTP) based on the aeromagnetic anomaly data, separated the gravity anomalies and the magnetic anomalies using the filtering method and the wavelet transform method, and obtained the regional gravity and magnetic anomalies and the multi-order wavelet transform approximation of gravity and magnetic anomalies. Combined with existing geological and geophysical research, we analyzed the features of the gravity anomalies and the magnetic anomalies, and discussed the deep structure of the eastern part of Junggar basin. The results showed that the upper mantle uplift in the eastern part of Junggar basin. The Junggar basin turned down under the northern Tianshan orogenic belt and the eastern Junggar orogenic belt. The regional high gravity anomaly, high magnetic anomaly and high resistivity anomaly in the northern part of the eastern part of Junggar basin may be mainly caused by the influx of larger density, stronger magnetic property and larger resistivity mantle substances into the middle crust along the fault in the northern margin of the Junggar basin.
