Ultra‐Mafic Cumulates From Kaupulehu, Hualālai Volcano, Hawai'i: Geochemical Resetting of Mantle‐Inherited Olivine

open access: yesGeochemistry, Geophysics, Geosystems
We characterized the chemical composition and microstructure of six ultramafic cumulates from the Kaupulehu lava flow, Hualālai (Hawai'i Island), to decipher their origin. The samples are mostly wehrlites with poikilitic textures.

A Comparative Study of the Fatty Acid Profile of Non-Edible and Edible Tissues of Raw and Processed Common Octopus (Octopus vulgaris)

open access: yesMarine Drugs
A comparative study of the fatty acid (FA) composition of non-edible (viscera) and edible (mantle and arm) tissues of octopus (Octopus vulgaris) was carried out.

Velocity model of the mantle structure under Sumatra and seismic activity of the area

open access: yesГеофизический журнал, 2014
Within the framework of a three-dimensional P-velocity model of the mantle of the South-East Asia, the mantle velocity structure beneath Sumatra and its surroundings has been considered with the identification of possible premises in the deep structure ...

Chemical Heterogeneities along the South Atlantic Mid-Ocean-Ridge (5-11°S): Shallow or Deep Recycling of Ocean Crust? [PDF]

open access: yes, 2011
Between 5° and 11°S, the Mid-Atlantic Ridge displays anomalous crustal thickness and geochemical compositions, thought to be related to either small scale upper mantle heterogeneities or a weak, diffuse mantle plume.

Mantle geoneutrinos in KamLAND and Borexino

open access: yes, 2012
The KamLAND and Borexino experiments have observed, each at ~4 sigma level, signals of electron antineutrinos produced in the decay chains of thorium and uranium in the Earth's crust and mantle (Th and U geoneutrinos).

The collision of feminisms, sexuality, and trafficking in persons in the Caribbean—A place for Kempadoo

open access: yesFeminist Anthropology, EarlyView.
Abstract The existence and development of feminist scholarship and practice have been revisited by feminist anthropologists and sociologists exploring it among the gendered cultural and historical dynamics of the Caribbean. Feminist Caribbeanists’ pioneering efforts that fit within this theoretical family have challenged the Global North status quo to ...

Comparative Nutritional and Healthy Values of Macro- and Microelements in Edible and Non-Edible Tissues of Raw and Processed Common Octopus (Octopus vulgaris)

open access: yesFoods
The macroelement (Na, Mg, P, S, K, and Ca) and microelement (Mn, Fe, Co, Cu, Zn, As, Cd, Sn, Ba, and Pb) composition of edible (arm and mantle) and non-edible (viscera) tissues of octopus (Octopus vulgaris) was studied.

High‐Titanium Zircon Rims in Rhyolite – A Reflection of Adiabatic Ascent?

open access: yesGeological Journal, EarlyView.
The ascent of granitic magma from source to emplacement is rapidly achieved through dyking, resulting in negligible heat loss to the surrounding wallrock (i.e., adiabatic). Zircon growth during ascent can record the changing magma conditions including adiabatic cooling and heating, resulting in high titanium rims on low titanium cores without ...

open access: yesThe Iowa Review, 2011
In the mirror I'm giving a lecture on geology, but when I touch my mouth, there's just some clay beads standing in for teeth. I think, Yeah, I ate the stamp with the wildflowers, but this is a whole passageway I was hoping to ditch. Dan and Julie are in the next room making out, so I splash some root beer on my face and continue preaching science. This
