The Spanish-Portuguese Central System (SPCS) is an Alpine Mountain range with crystalline basement characterized by a two-layer rheological structure. This structure formed after primary (protolith) and secondary (tectonometamorphic) processes during the extensional collapse of Variscan Orogen. SPCS usually controlled foreland-directed thrusts strike-slip faults. However, eastern dominated NW-d...

Production of Metallogenic-prognostic map (MPM) was preceded by the preparation of instructions that define three phases of work: preparation (with preparation of the Project), realization of field and laboratory research and data processing with production of different maps and, finally, production of the prognostic map with the accompanying instruction book. During the Project realization, th...

The brittle deformation of internal zones the Rif chain, corresponding to southern margin West Alboran Basin, is not or poorly dated because lack stratigraphic constraints. We provide for first time a direct dating in Ceuta peninsula located westernmost part Gibraltar arc. 40Ar/39Ar illite ages from fault gouges footwall and hanging wall Shear Zone range 11.9 ± 2.5 Ma 15.7 1.7 14.7 0.1 18.9 0.8...

Supradetachment basins at passive rifted margins are a key witness of major-continental extension, and they may preserve record from which the amount rates extension metamorphic core complex exhumation be reconstructed. These have mainly been recognised in back-arc orogenic collapse settings, with few examples margins. Using 2D 3D seismic reflection, wellbore, gravity anomaly data, we here char...

Abstract The Brenner normal fault bounds the Tauern Window to west and accommodated a significant portion of orogen-parallel extension in Eastern Alps. Here, we use zircon (U–Th)/He, apatite fission track, (U–Th)/He dating, thermokinematic modeling, topographic analysis constrain exhumation history western footwall fault. ZHe ages from an E–W profile (parallel slip direction fault) decrease wes...

The Bilila-Mtakataka Fault (BMF), at the southern end of western branch East African Rift System (EARS), has been used in various scaling relation studies and arguments about strength lithosphere. We present evidence for a similar, though more degraded, frontal scarp on graben-bounding synthetic Chirobwe-Ntcheu (CNF), showing that this fault is active simultaneously with BMF. deployed 17 geopho...

Despite decades-long debate over the mechanics of low-angle normal faults (LANFs) dipping less than 30°, many questions about their strength, stress, and slip remain unresolved. Recent geologic geophysical observations have confirmed that gently detachment can at such shallow dips host moderate-to-large earthquakes. Here, we analyze first 3D dynamic rupture models to assess how different stress...

Fractures strongly influence the permeability of geologic formations, and because most fractures in subsurface are below resolution geophysical methods, predicting spatial evolution fracture networks is important for groundwater resources, oil gas production, geothermal energy. Previous researchers have established that variations lithologic mechanical properties propagation joints layered rock...

Metamorphic core complexes in the western North American Cordillera are commonly interpreted as result of a single phase large-magnitude extension during middle to late Cenozoic. We present evidence that mylonitic shear zones Harcuvar and Buckskin-Rawhide west-central Arizona also accommodated an earlier Late Cretaceous early Paleocene. Microstructural data indicate substantial top-NE mylonitiz...

In recent years, significant advances have been made in the exploration of Carboniferous volcanic reservoirs Hongche Fault Zone Junggar Basin China, showing good prospects for further exploration. However, large variation physical properties crude oil and complex distribution rule inhibit one-step this study, PM scale biodegradation source were studied using experimental methods that target pro...
