Геодинамика и тектонофизика, 2016 Paradoxically, the lists of “proxies” of both plate- and plume-related settings are devoid of even a mention of the high-grade metamorphic rocks (granulite, amphibolite and high-temperature eclogite facies).

Phase change in subducted lithosphere, impulse, and quantizing Earth surface deformations [PDF]
Solid Earth, 2015 The new paradigm of plate tectonics began in 1960 with Harry H. Hess's 1960 realization that new ocean floor was being created today and is not everywhere of Precambrian age as previously thought. In the following decades an unprecedented coming together

The impact of forced closure on proppant distribution of hydraulic fracturing in shale formations
Deep Underground Science and Engineering, EarlyView.Research findings demonstrate that implementing forced closure within shale formations can remarkably mitigate proppant settlement, concurrently increasing the effective propped surface area from 29.74% to 38.68%. Abstract Forced closure is widely used in conventional oil and gas reservoirs to promote uniform proppant placement.

Middle to Late Miocene Contractional Deformation in Costa Rica Triggered by Plate Geodynamics [PDF]
, 2017 Contractional deformation in Costa Rica is usually attributed to the subduction of the aseismic Cocos Ridge. In this work, we review the evidences for contraction in the middle to late Miocene, prior to the arrival of the Cocos Ridge at the Middle ...

Deep Underground Science and Engineering, EarlyView.Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

BONINITES THROUGH TIME AND SPACE: PETROGENESIS AND GEODYNAMIC SETTINGS
Геодинамика и тектонофизика, 2016 The article provides an overview of boninitic magmatism occurrences in space and time and shows that the boninite rock series were generated through the entire geological history of the Earth.

Deep Underground Science and Engineering, EarlyView.Aluminum‐enhanced afterburning renders AE explosives more hazardous than conventional ones. Corrugated steel linings reduce far‐field AE blast overpressure by ~50% through wave reflection and dissipation. The developed model accurately predicts peak pressure (<10% error) and arrival time (<3% error), supporting protective design.

Thermal History of the Earth: On the Importance of Surface Processes and the Size of Tectonic Plates
Geochemistry, Geophysics, Geosystems, 2020 Geochemical constraints on mantle temperature indicate a regular decrease by around 250 K since 3 Ga. However, models of Earth's cooling that rely on scaling laws for thermal convection without strong plates are facing a thermal runaway backwards in time,
