Assessment of tectonic activities of Ghorveh- Dehgolan basin by using geomorphic indices [PDF]
جغرافیا و توسعه, 2021 The morpho-tectonic indices of the basin are used to investigate the active tectonics. The study area is part of the Sefidrud basin. In this study, to assess tectonic activities in the Ghorveh- Dehgolan basin, five morphometric indices of the Relative ...

Geochemistry, Geophysics, Geosystems, 2023 A tectonic window into the upper 2,000 m of oceanic crust generated at the superfast spreading (∼142 mm/yr) southern East Pacific Rise exposes a continuous layered structure of basaltic lavas and sheeted dikes over gabbroic rocks.

Fissure Ridges: A Reappraisal of Faulting and Travertine Deposition (Travitonics)
Geosciences, 2021 The mechanical discontinuities in the upper crust (i.e., faults and related fractures) lead to the uprising of geothermal fluids to the Earth’s surface. If fluids are enriched in Ca2+ and HCO3-, masses of CaCO3 (i.e., travertine deposits) can form mainly

Fault rock heterogeneity can produce fault weakness and reduce fault stability [PDF]
Nature Communications, 2022 Geological heterogeneity is abundant in crustal fault zones; however, its role in controlling the mechanical behaviour of faults is poorly constrained. Here, we present laboratory friction experiments on laterally heterogeneous faults, with patches of strong, rate-weakening quartz gouge and weak, rate-strengthening clay gouge. The experiments show that

Geophysical characteristics of the Terror Rift, West Antarctica
Dizhi lixue xuebao, 2021 In this paper, we investigated the Terror Rift where the last stage of Cenozoic rifting in the West Antarctic Rift System (WARS) took place. The International published and domestic sampled during CHARE seismic reflection profiles are utilized. Combining
