Assessment of tectonic activities of Ghorveh- Dehgolan basin by using geomorphic indices [PDF]

open access: yesجغرافیا 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 ...

Fissure Ridges: A Reappraisal of Faulting and Travertine Deposition (Travitonics)

open access: yesGeosciences, 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

Geophysical characteristics of the Terror Rift, West Antarctica

open access: yesDizhi 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

Discrete Element Modelling of Sedimentation and Tectonics: Implications for the Growth of Thrust Faults and Thrust Wedges in Space and Time, and the Interpretation of Syn-Tectonic (Growth) Strata

open access: yesFrontiers in Earth Science, 2021
Thrust faults, and thrust wedges, are an important part of the surface morphology and structure of many contractional mountain belts. Analogue models of thrust wedges typically provide a map- and/or side-view of their evolution but give limited insight ...

Neogene faulting and volcanism in the Victoria Land Basin of the Ross Sea, Antarctica

open access: yesEarth and Planetary Physics, 2022
The Neogene Terror Rift in the Antarctic Victoria Land Basin (VLB) of the Ross Sea, Antarctica, is composed of the Discovery Graben and the Lee Arch. Many Neogene volcanoes are aligned in the north-south direction in the southern VLB, belonging to the ...

Controls on Gas Emission Distribution on the Continental Slope of the Western Black Sea

open access: yesFrontiers in Earth Science, 2021
The continental slopes of the Black Sea show abundant manifestations of gas seepage in water depth of <720 m, but underlying controls are still not fully understood.

Regularities of crustal faulting and tectonophysical indicators of fault metastability

open access: yesГеодинамика и тектонофизика, 2018
The problem of forecasting seismic hazards is discussed. The stress state data characterizing various aspects of brittle failure are reviewed in detail. It is shown that the most convenient tool for analyzing such data is the Mohr stress diagram and the ...

Deformational regimes and kinematic conditions of modern tectonic faulting within the limits of the Mountain Crimea. 2

open access: yesГеофизический журнал, 2015
Description and analysis of stereographic models of deformational regimes of tectonic faulting and corresponding kinematic conditions given in part 1 [Wolfman, 2014] have been continued.

“Empirical Prewhitening” Spectral Analysis Detects Periodic but Inconsistent Signals in Abyssal Hill Morphology at the Southern East Pacific Rise

open access: yesGeochemistry, Geophysics, Geosystems, 2020
The existence, or not, of periodicities in abyssal hill morphology has been vigorously debated in recent publications, and some have hypothesized that such periodicities are evidence of the impact of Milankovitch cycle‐caused sea level fluctuations on ...

RECENT GEODYNAMICS OF FAULT ZONES: FAULTING IN REAL TIME SCALE

open access: yesГеодинамика и тектонофизика, 2015
Recent deformation processes taking place in real time are analyzed on the basis of data on fault zones which were collected by long-term detailed geodetic survey studies with application of field methods and satellite monitoring.A new category of recent
