Abstract

Southwestern slopes of Rila Mountain and northern parts of the Mesta graben are one of the least studied areas in terms of brittle tectonics. We carried out studies in the area around Bachevo and Dobarsko villages aiming to observe the fault zone network. The Bachevo fault zone is defined as Paleogene–Eocene Low-Angle Normal Fault that later underwent strike-slip and normal fault reactivation. The zone is an important tectonic boundary, separating the ca. 56 Ma Kapatnik granite from the Ograzhden Unit. Another important and possibly younger extensional zone is the Semkovo Fault. The relationships between the both zones are unclear. In terms of the Quaternary tectonics, it is important to differentiate between the Semkovo fault and the active Southeastern Rila Normal Fault. There are no data about Quaternary activity of the Bachevo fault zone.

里拉山西南坡和梅斯塔地堑北部地区是脆性构造研究最少的地区之一。我们在巴切沃(Bachevo)和多巴尔斯科(Dobarsko)村周围地区进行了研究,旨在观察断层带网络。巴切沃断层带被定义为古新世低角度正断层,后来经历了走向滑动和正断层的重新激活。该断层带是一个重要的构造边界,将约 56 Ma 的卡帕特尼克花岗岩分隔开来。56 Ma 的卡帕特尼克花岗岩与奥格拉日登单元之间的重要构造边界。另一个重要且可能更年轻的延伸带是塞姆科沃断层。这两个地带之间的关系尚不清楚。就第四纪构造而言,必须区分 Semkovo 断层和活跃的东南里拉正断层。没有关于巴切沃断层带第四纪活动的数据。
