Abstract:

The article focuses on the deformation and strain-stress analysis of the Earth’s crust under external thermal loading. More specifically, the influence of cyclic changes in the surface temperature field on the stress and displacement inside the crust over a two-year time span is investigated. The finite element program MSC.Marc Mentat was used to calculate the stresses and displacements. For practical analysis reasons, the Earth’s crust is simplified as a planar, piecewise homogeneous, isotropic model (plane strain), and time-varying temperature functions of illumination (thermal radiation) fr

Abstract:

Snapshot/Lay Summary—In 1958 Charles Hapgood proposed that mass imbalances created by a buildup of polar ice could displace the earth’s crust over the mantle and that resulting pole shifts were the cause of catastrophic climate changes and ice ages. We contrast the first part of his theory with plate tectonics and true polar wander and propose a new mechanism that is triggered by short-term reversals of the geomagnetic field that “unlock” the crust from the mantle, driven by earth–moon–sun tidal forces, the same forces that move earth’s oceans. It is shown that by combining a modified version

Present-day stress filed in the Hoang Sa archipelago and adjacent areas is determined through the earthquake’s focal mechanism parameters that have been recorded during a time period of more than 100 years. The geometric parameters of the faults (such as the location, strike and dip angles as well as depth, length…) are determined by satellite-derived gravity, seismic data and stress fields. In this study, predictive determination of the magnitude and tendency of the relative displacement of the Earth’s crust is carried out by calculating and assessing the relationship between the stress field

Abstract:

Abstract This study investigates elastic deformation driven by the Hall drift in a magnetized neutron-star crust. Although the dynamic equilibrium initially holds without elastic displacement, the magnetic-field evolution changes the Lorentz force over a secular timescale, which inevitably causes the elastic deformation to settle in a new force balance. Accordingly, elastic energy is accumulated, and the crust is eventually fractured beyond a particular threshold. We assume that the magnetic field is axially symmetric, and we explicitly calculate the breakup time, maximum elastic energy stored

Abstract:

It is known that the source of a tectonic earthquake in the framework of the theory of elasticity and viscoelasticity is considered to be displacement along a certain fault surface. Usually, when describing a source, the geometry of the fault surface is simplified to a flat rectangular area. The displacement vector is assumed to be constant. In this paper, we propose a model of an earthquake source in the form of a displacement with a constant vector along a stochastic uneven surface. A number of standard assumptions are made during the modeling. We take into account only the elastic propertie

A 3D model of the Earth’s crust for the Laptev Sea continental margin and the adjacent part of the Eurasian Basin was built using the latest seismic and gravity data. The thickness of the Earth’s crust in the research area equals 7–11 km, which corresponds to a highly extended continental or oceanic crust. Basement formation and sedimentation in this area most likely began in the Late Jurassic. The south-eastern part of the Eurasian Basin is separated from the rest of the basin by a dextral shear zone, the displacement along which during the Paleogene was more than 100 km.

Abstract:

Geophysical studies suggest that the thin crust characteristic of the Basin and Range Province extends eastward beneath the west margin of the Colorado Plateau and Rocky Mountain regions. In Arizona and Utah, zones perhaps over 100 km wide may be defined, bounded on the west by the east limit of upper crustal normal faults that account for more that 10% extension and on the east by the east limit of thinning beneath the Colorado Plateau. A discrepancy exists within these zones between the negligible extension measurable in the upper crust and the substantial extension apparent from crustal thi

Weathered crust karst reservoirs with intricately interconnected fractures and caves are common but challenging enhanced oil recovery (EOR) targets. This paper investigated the remaining oil distribution rules, formation mechanisms, and EOR methods through physical experiments on acrylic models resembling the geological features of weathered crust reservoirs. Acrylic models with precision dimensions and morphologies were fabricated using laser etching technology. By comparing experiments under different cave filling modes and production well locations, it was shown that a higher cave filling e

In the winter season, we can observe the increased number of personal injuries and road vehicle accidents because of ice coating on paved roads. Surface refining from icing field involves two process operations: breaking it up and transporting the resulting segments. The basic process prevailing in cleaning effective output is the cutting process, i.e. the separation of icy fragments from the pavement with the cutting tools of special machines. The purpose of the research is to simulate the ice crust breaking influenced by the device designed by the authors. The modeling of ice flow failure is

It was one of the two strongest instrumentally recorded earthquakes that hit the territory of the Republic of Croatia in the last hundred years, and the strongest earthquake in the Banovina area after the great earthquake in 1909. Increased seismic activity in this area is caused by two vertical strike–slip faults, Pokupski and Petrinjski. This artic

The CAYSEIS experiment acquired a 180-km-long seismic refraction and gravity profile across this transform margin, ∼70 km to the west of the Mid-Cayman Spreading Centre (MCSC). This profile shows the crustal structure across a transform fault system that juxtaposes Mesozoic-age continental crust to the south against the ∼10-Myr-old ultraslow spread oceanic crust to the north.

Detailed structural maps of two granitoid complexes in the Wabigoon Subprovince are used to test three diapir hypotheses advanced in earlier papers. The gneiss masses of, and individual domes within, the complexes fail the test for solid-state diapirism. The gneiss domes also fail the test for tensile bending caused by hypothetical magmatic diapirs in the subsurface. An oval pluton located near the best-exposed gneiss dome proves to be a synformal sheet rather than a funnel-shaped magmatic diapir. This pluton could be a syenite–diorite phacolith emplaced into a concordant zone of dilation duri

The paper examines the spatial relationship between the seismoactive zones in eastern Priamurye (М ≥ 5) and the regional faults and hidden fault zones identified from the gravity and magnetic anomaly axes. The seismoactive zones where earthquakes with М ≥ 5 occurred are mostly confined to the regional faults, though such a relationship has not been validated in two cases. The seismoactive zones are detected both at the regional fault intersection and in areas where the regional faults intersect with the hidden faults of various ranks.

The sources of forces and deformations and the influence of the anisotropy of the lithosphere on the evolution of the Earth’s crust based on evidence from the Sarmatia plate are considered.

Hydraulic fracturing in geothermal wells is referred to as hydro-shearing and the aim is to improve the conductivity of natural fractures.

Large-scale lateral mobility of the Earth’s lithosphere (mobilism) was a hotly debated issue in Earth Sciences during some two decades following publication of Wegener’s (1912) theory of continental displacement. The final acceptance of lithospheric mobility was brought about with the plate tectonics revolution during the late 1960s. Support for mobilism was rather popular in certain European countries during the 1920s, whereas the reactions in North America were mostly hostile. One of the very few influential mobilists in the New World was Reginald Aldworth Daly of Harvard University. The pre

Abstract Global and regional surveys of earthquakes show that empirically determined b-values of the Gutenberg-Richter distribution are remarkably stable, generally limited to values of −1 ± 0.2. Here I interpret observations from California, New Zealand, and Japan to suggest that the stability of the b-value is a manifestation of a physical process; specifically, the tendency of crustal strains to organize along relatively discrete zones. Given a portion of the earth's crust subject to a displacement field, displacement is accommodated by a system of fault lengths that obey a power law distri

Abstract The Main Karatau fault is a classical crustal strike-slip zone. It originated as a continental rift structure in the Late Proterozoic and had been developed incessantly for almost 1 billion years as inherited structure. The fault was subjected to polyphase deformations associated with both dextral and sinistral shifts. The Main Karatau fault crosses the Earth’s crust, including the structures of granite-metamorphic layer and granulite-basitic layer and fades without crossing the Moho discontunious.
