Selective sampling of asteroids, the Moon, and Mars: Factors affecting the numerical abundances of members of meteorite groups

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Meteorite collection inventories show that many related meteorite groups have very different numerical abundances (e.g., lunar versus Martian meteorites; Eagle Station pallasites versus main‐group pallasites; eucrites versus diogenites; ungrouped Antarctic irons versus ungrouped non‐Antarctic irons; carbonaceous chondrite‐related (CC) iron ...

An investigation into the controls of granite plutonism in the Sierra da Freita region, Northern Portugal [PDF]

open access: yes, 2012
The Serra da Freita region of north central Portugal was chosen for study as it displays the complex relationships between regional structure, plutonism, regional and contact metamorphism typical of this part of Iberia.

A Role for High Mobility Group Box 1 (HMGB1) Release in the Pathogenesis of Gastroesophageal Reflux Disease

open access: yesNeurogastroenterology &Motility, EarlyView.
Incubation of esophageal epithelial cells with a weakly acidic (pH 5) bile salt (deoxycholic acid) induces translocation of HMGB1 from the nucleus to the cytosol, and its subsequent release from the cell. This process can be ameliorated by pre‐treatment with the antioxidant, curcumin.

Field Studies of the Archean in Grand Canyon [PDF]

open access: yes, 1933
The oldest rocks of Arizona which form the precipitous walls of the inner or granite gorge of the Grand Canyon have never received the intensive study that has been given to their counterparts over the great northeastern plains of Canada, in the ...

Thermal Alteration of Labile Elements in Carbonaceous Chondrites

open access: yes, 2018
Carbonaceous chondrite meteorites are some of the oldest Solar System planetary materials available for study. The CI group has bulk abundances of elements similar to those of the solar photosphere.

The Chamrousse Ophiolite (Western Alps, France): Relict of a Devono‐Carboniferous Ocean

open access: yesTerra Nova, EarlyView.
ABSTRACT The Chamrousse ophiolite (Western Alps, France) is one of the best‐preserved Variscan relicts of Cambro‐Ordovician oceanisation within the northern Gondwana margin. This study presents new in situ U–Pb isotope analyses on zircon grains from that ophiolite, revealing that the oceanic stage in Chamrousse has occurred 150 Ma later than estimated.
