摘要

基耶是一个独特的国家，其变形模式是由欧亚大陆、非洲、阿拉伯半岛和微板块安纳托利亚三个主要板块在最近一段时间内活跃运动而形成的。这种变化形成了一个巨大的断层网，定义了板块边界和板块内断层。萨夫润断裂带是2023地震区西侧的一条板内走滑断层，其活动性引发了诸多争议。本文基于断层滑动数据的实地测量，研究并报道了SFZ的几何、结构和运动学特征。SFZ的地质演化至少经历了两个不同的变形阶段；较老的北北东—南南西挤压构造直至中上新世，最年轻的北南南挤压和东西向伸展形成的走滑体制。结果表明，SFZ是一条重新激活的逆断层，其现今形态是一个由北、中、东三段和两个收缩台阶组成的活动左旋走滑构造，反映了以走向平行断谷为标志的强烈地貌指示。

Active tectonics and kinematic architecture of intraplate strike-slip fault: Savrun fault zone, SE Türkiye

Türkiye is a unique country whose deformation pattern has been formulated in terms of three main plates Eurasia, Africa, Arabia and microplate Anatolian that are actively moving in recent time. This variety creates a giant fault network defining the plate boundaries and intraplate faults. Savrun Fault Zone (SFZ) is one of the intraplate strike-slip faults near west of the 2023 earthquakes area and many controversies have arisen about its activeness. In this study, it is investigated and reported on the geometric, structural, and kinematic characteristics of the SFZ based on field measurements of fault-slip data. At least two different deformation phases have been recognized in the geological evolution of the SFZ; older NNE-SSW compressional tectonic up to Middle Pliocene and the youngest strike-slip regime created by N-S compression and E-W extensional direction. According to the results, SFZ is a reactivated reverse fault and its the present-day configuration is an active sinistral strike-slip architecture comprising three segments (north, middle and east) and two contractional stepovers reflecting strong geomorphic indicators marked by strike parallel fault valley.

期刊介绍： Journal of Asian Earth Sciences has an open access mirror journal Journal of Asian Earth Sciences: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The Journal of Asian Earth Sciences is an international interdisciplinary journal devoted to all aspects of research related to the solid Earth Sciences of Asia. The Journal publishes high quality, peer-reviewed scientific papers on the regional geology, tectonics, geochemistry and geophysics of Asia. It will be devoted primarily to research papers but short communications relating to new developments of broad interest, reviews and book reviews will also be included. Papers must have international appeal and should present work of more than local significance. The scope includes deep processes of the Asian continent and its adjacent oceans; seismology and earthquakes; orogeny, magmatism, metamorphism and volcanism; growth, deformation and destruction of the Asian crust; crust-mantle interaction; evolution of life (early life, biostratigraphy, biogeography and mass-extinction); fluids, fluxes and reservoirs of mineral and energy resources; surface processes (weathering, erosion, transport and deposition of sediments) and resulting geomorphology; and the response of the Earth to global climate change as viewed within the Asian continent and surrounding oceans.
