Oxygen Isotope Variations of Basaltic Lavas and Upper Mantle Rocks [PDF]

open access: yes, 2001
This chapter summarizes the oxygen isotope geochemistry of terrestrial basalts and their mantle sources, including the conceptual framework for interpreting such data and the phenomenology of known variations.

Spatial and depth‐dependent variations in magma volume addition and addition rates to continental arcs: Application to global CO_2 fluxes since 750 Ma [PDF]

open access: yes, 2019
Magma transfer from the mantle to the crust in arcs is an important step in the global cycling of elements and volatiles from Earth's interior to the atmosphere. Arc intrusive rocks dominate the total magma mass budget over extrusive rocks.

Mingling and mixing features in basaltic Andesites of the Eastern Cordillera (Central Andes, 24°s): a petrographic and microanalytical study [PDF]

open access: yes, 2006
The basaltic andesites of the Diego de Almagro volcanic complex (Central Andes, 24°S, 66°W) were erupted during Late Miocene at 300 km from the active arc, in the Eastern Cordillera, at the easternmost end of an important strike-slip structure, the ...

New Geothermal Prospect in North-Eastern Morocco [PDF]

open access: yes, 2010
Geothermal data has been indicating promising potentialities in the north-eastern Morocco. This paperpresents new temperature data, recently recorded in water borehole located in the Berkane and Oujda areas.

Synthesis of thin-film black phosphorus on a flexible substrate

open access: yes, 2015
We report a scalable approach to synthesize a large-area (up to 4 mm) thin black phosphorus (BP) film on a flexible substrate. We first deposited a red phosphorus (RP) thin-film on a flexible polyester substrate, followed by its conversion to BP in a ...

Fast cooling following a Late Triassic metamorphic and magmatic pulse: implications for the tectonic evolution of the Korean collision belt

open access: yes, 2015
International audienceWe discuss the evolution of Korea in the context of a relatively short-lived, tectonically induced, magmatic and metamorphic pulse that affected large portions of the crust of the peninsula's southern part during the Late Triassic ...

Tectonics and volcanisms of Mars [PDF]

open access: yes
Televised images of Mars transmitted from interplanetary stations are used to develop a theory of the structure and development of the planet. Crater chronology, the structure of planetary bodies in the Earth group, and a comparison of the Earth ...

Mesozoic spreading kinematics: consequences for Cenozoic Central and Western Mediterranean subduction [PDF]

open access: yes, 2017
The highly complex tectonics of Central and Western Mediterranean subduction are well documented, but there is significant debate about the responsible dynamics.

Late Cenozoic structure and tectonics of the southern Sierra Nevada–San Joaquin Basin transition, California [PDF]

open access: yes, 2019
This paper presents a new synthesis for the late Cenozoic tectonic, paleogeographic, and geomorphologic evolution of the southern Sierra Nevada and adjacent eastern San Joaquin Basin.

Paleo- stress and strain rates in an intra-arc strike-slip fault, Sierra Nevada, California [PDF]

open access: yes, 2008
Structures and microstructures of the Proto-Kern Canyon fault (PKCF), a 130-km-long dextral strike-slip shear zone of the southern Sierra Nevada batholith, provide constraints on displacement, flow stress, and strain rate during arc formation.
