Abstract

Abstract

Characteristics of gravity and magnetic anomalies and their geological significance are analyzed in order to identify prospective zones for hydrocarbon exploration in the Nanweixi Basin. The northern depression and northern uplift of the Nanweixi Basin are characterized by high gravity and high magnetism, indicating strong volcanic activities in this region. The central depression, southern uplift, and the northern part of the southern depression are characterized by local high gravity and magnetic anomalies with clumpy and isoaxial shape on the overall low gravity and magnetic amomaly background, which is a comprehensive reflection of volcanic rocks and carbonate platforms. The thickness of the Cenozoic in the Nanweixi Basin is characterized by NE trending thin-thick bands, and the thickness in the southern depression is the largest, followed by the central depression. The northern part of the basin is located in the upheaval of the Moho surface, while the Moho surface is relatively deep in the southern part of the basin, which manifests as the feature of thinned continental crust. Curie surface of the northern depression and northern uplift are relatively shallow, which may be related to the strong extension and thinning of lithosphere and the mantle material invasion caused by the expansion of the South China Sea. Curie surface in the central depression and the southern uplift is shallower than which is in the south depression, indicating that the central depression and the southern uplift have much stronger underlying thermal activities than those of the southern depression. The Nanweixi Basin has relatively favourable hydrocarbon prospects from the gravity and magnetic field characteristics and their inversion results and the petroleum geological features. The central depression, southern uplift and the southwestern peripheral regions of the basin are the best potential hydrocarbon prospect zones, followed by the southern depression. In the favourable hydrocarbon zones, some high gravity anomaly area with local clumpy and isoaxial shape may indicate carbonate platform and organic reef, which should be the future exploration target.
