The Role of Plate Tectonic-Climate Coupling and Exposed Land Area in the Development of Habitable Climates on Rocky Planets [PDF]

, 2015
The long-term carbon cycle is vital for maintaining liquid water oceans on rocky planets due to the negative climate feedbacks involved in silicate weathering. Plate tectonics plays a crucial role in driving the long-term carbon cycle because it is responsible for CO$_2$ degassing at ridges and arcs, the return of CO$_2$ to the mantle through ...

Spatio-temporal evolution of intraplate strike-slip faulting: the Neogene-Quaternary Kuh-e-Faghan Fault, Central Iran [PDF]

, 2016
Central Iran provides an ideal region to study the long-term morphotectonic response to the nucleation and propagation of intraplate faulting. In this study, a multidisciplinary approach that integrates structural and stratigraphic field investigations ...

Nuclear parcellation of pontine catecholaminergic and cholinergic neurons in gray parrots and pied crow brains

The Anatomical Record, EarlyView.
Immunohistochemical staining for tyrosine hydroxylase reveals the neurons forming the locus coeruleus complex in the pontine region of the brain of the Congo gray parrot. The appearance and parcellation of the locus coeruleus complex in birds shows many similarities, but also differences to that observed in mammals.

Kuwae, Epi and Tongoa Islands: Transformations of a volcanic landscape in central Vanuatu

Archaeology in Oceania, EarlyView.
ABSTRACT This paper presents a detailed overview of archaeological research undertaken on Epi and Tongoa, in central Vanuatu. These islands were previously connected to one another and respectively formed the western and eastern portions of Kuwae, one of the largest islands in the Vanuatu archipelago, until the catastrophic Tombuk volcanic eruption ...

Whole planet coupling between climate, mantle, and core: Implications for the evolution of rocky planets [PDF]

Geochemistry, Geophysics, Geosystems, 17(5), 1885-1914 (2016), 2017
Earth's climate, mantle, and core interact over geologic timescales. Climate influences whether plate tectonics can take place on a planet, with cool climates being favorable for plate tectonics because they enhance stresses in the lithosphere, suppress plate boundary annealing, and promote hydration and weakening of the lithosphere.

Geological Evidence for the Operation of Plate Tectonics throughout the Archean: Records from Archean Paleo-Plate Boundaries

Journal of earth sciences, 2018
Plate tectonics describes the horizontal motion of rigid lithospheric plates away from midoceanic ridges and parallel to transforms, towards deep-sea trenches, where the oceanic lithosphere is subducted into the mantle.

Along-Strike Reservoir Development of Steep-Slope Depositional Systems: Case Study from Liushagang Formation in the Weixinan Sag, Beibuwan Basin, South China Sea

Energies, 2023
Seismic, core, drilling, logging, and thin-section data are considered to analyze the reservoir diversity in the east, middle, and west fan of the Liushagang Formation in the steep-slope zone of the Weixinan Sag, Beibuwan Basin.

Scaling of plate-tectonic convection with pseudoplastic rheology [PDF]

J.Geophys.Res.115:B11405,2010, 2010
The scaling of plate-tectonic convection is investigated by simulating thermal convection with pseudoplastic rheology and strongly temperature-dependent viscosity. The effect of mantle melting is also explored with additional depth-dependent viscosity.

Itinerant curriculum theory: People's theory against the field's epistemicidal ethos

The Curriculum Journal, EarlyView.
Abstract The field of curriculum studies suffers from a glaring theoretical impasse. Much of this impasse has been rightly attributed to the triumphalism of the neoliberal wave that has massacred the educational hemisphere with policies and practices that reduce pedagogy to an instrumentalist praxis directly associated with the thirsty desires and ...
