The Dayingezhuang orogenic gold deposit, located in the northwestern Jiaodong Peninsula, is hosted by Zhaoping detachment fault, but paleostress regime during mineralization period remains poorly understood. In this study, a series of numerical modeling experiments with variable stress conditions were carried out using FLAC3D software to determine orientation and fluid migration processes ore-f...

The structural and subsidence history of the Neogene Transylvanian basin is reviewed in order to analyse its relation to the tectonic and erosional history of the surrounding Carpathian mountains that has been defined by apatite fission track data from previous studies. The main processes studied are redistribution of mass by erosion, and tectonic loading. A mass balance is calculated between m...

The structural analysis of large intracontinental wrench faults is fundamental for deciphering the long-term evolution continental crust in complex areas terms their geodynamic and large-scale crustal block displacements. In this contribution, we demonstrate a pre-Miocene dextral activity present-day left-lateral Great Kavir - Doruneh Fault System (GKDFS, Central Iran), one major active strike-...

Tectonic stresses governed by the Arabia – Central Iran collision are transferred throughout Iranian Plateau. The orientation of maximum horizontal stress (σ 1 ) significantly changes (~90°) in Persian block NW Iran. However, exact spatial extent and boundary conditions for these poorly defined. This study investigates late Cenozoic regime a key region including Mahneshan Mianeh Basin (MMCB), G...
