Abstract

Based on the data of relief analysis, the gravity and magnetic anomaly axes, earthquake foci sequences, and Vp/Vs ratio values, tectonic fracturing of the lithosphere is studied and tectonic submeridionally and sublatitudinally oriented fracturing zones are distinguished in the Priamurye region. Separate segments of extended submeridional and sublatitudional fracturing zones are evidenced from the regional faults detected using the geological methods. Submeridionally oriented tectonic fracturing zones are mostly revealed, which do not correlate with the regional faults. Fracturing zones of similar orientation which are displayed in lineaments of different type and correlate with the seismoactive zones may be considered as hidden faults.

准Sub下和次纬断层对普里穆尔耶地区岩石圈的构造压裂(来自地球物理数据和地貌分析)

摘要

根据地貌分析数据,重力和磁异常轴,地震震源序列和V p / V s比值,研究了岩石圈的构造断裂,并在Priamurye地区区分了构造性的近中和纬下定向断裂带。使用地质方法检测到的区域性断层可以证明扩展的子午线和子午线断裂带的分离段。沿地下构造断裂带大部分被揭示出来,与区域断层无关。在不同类型的构造中显示并与地震活动带相关的相似取向的压裂带可以被认为是隐伏断层。
