Zusammenfassung: | In this paper, the gravity and magnetic data and the preliminary results of the interpretation of the artificial seismic depth sounding in the Pearl River Estuary are combined with the geological data for the discussion of the most important northeast fault in the Pearl River Delta region in terms of the characteristics of deep strata of Guangzhou-Enping fault. It is believed that the Guangzhou-Enping fault is an NE-trending deep fault with a cutting depth of more than 30km, a depth of Moho, a steep dip, and the largest extent in the Pearl River Delta, and has a certain cut with the near EW-oriented fault. Therefore, the Guangzhou-Enping fault is active to some extent which provides a channel for deep material upwelling. The deep flow of molten material is the main component of the low-velocity zone of the lower and middle crust, and the surface is characterized by rich mineral resources, hot springs and basalt exposure. |
