Hydrothermal origin of metabolic phosphorylation
The FEBS Journal, EarlyView.Serpentinizing hydrothermal vents are candidate sites for biochemical origins. They generate extremely reducing conditions, depositing phosphite (HPO32−) and transition metals, including palladium, in the native (zero‐valent) state. Schlikker et al.

Crustal structure of the spreading plate boundary in Iceland and the north Atlantic from gravity data [PDF]
, 1994 Gravity datasets from two geothermal areas in Iceland, an Iceland-wide gravity dataset, and marine gravity data from the Reykjanes Ridge at 58˚N, which can be seen as the submarine extension of the Icelandic accretionary system, have been studied in this

Patience Stones: Material Encounters for Slow Currents of Pedagogy
International Journal of Art &Design Education, EarlyView.Abstract This article moves across sites in Canada and Japan with the practice of making Patience Stones (Sang‐e Saboor), a biodegradable, dough‐based artistic and pedagogical object that invites artist–teachers and artist–learners into with‐nessing and slow becoming.

Growth and Chemical Evolution of the Kohistan Arc Crust, Northern Pakistan, Western Himalayas
Geochemistry, Geophysics, GeosystemsFossil arcs which expose the middle‐lower crust have the potential to shed light on active arc processes because magmatic rocks from the entire history of the arc can be examined.

Increased metamorphic conditions in the lower crust during oceanic transform fault evolution [PDF]
Solid EarthOceanic transform faults connect the segments of active spreading ridges that slide past each other. In a classical view, transform faults are considered conservative, where no material is added or destroyed.

The habitat use of ariid catfishes in coral reefs in northeastern Brazil
Journal of Fish Biology, EarlyView.Abstract Ariidae species occur across a wide range of habitats from freshwater to fully marine environments and are typically associated with soft‐bottom substrates. However, they are sometimes associated with hard‐bottom substrates such as coral reefs, but such association is poorly documented.

EARTH CRUST IN OCEANS AND STRIP ANOMALIES OF MAGNETIC FIELD
Геологія і корисні копалини Світового океану, 2019 Examples of the isolation and interpretation of the strip anomalies of the magnetic field of the oceans are considered. Data were used on the eastern edge of the Pacific Ocean over most of the western coast of North America and on the Knipovich Ridge at ...

Mafic High‐Pressure Rocks Are Preferentially Exhumed From Warm Subduction Settings
Geochemistry, Geophysics, Geosystems, 2018 The oceanic crust that enters a subduction zone is generally recycled to great depth. In rare and punctuated episodes, however, blueschists and eclogites derived from subducted oceanic crust are exhumed.

Journal of Metamorphic Geology, EarlyView.ABSTRACT Zircon is a common, highly refractory accessory mineral found in sedimentary, igneous and metamorphic rocks that forms through various processes (e.g., magmatic, hydrothermal, metamorphic growth and recrystallization). Trace element compositions of detrital zircon have been widely applied to understanding tectonic processes and continental ...
