Earth's Radiogenic Heat Production and the Composition of the Deep Continental Crust
(2022)Much of the continental crust, the 40+ km thick plates of rock that make up the outer shell of our planet, is inaccessible to us living on its surface. Thus its composition is a mystery. We lack the technology to sample ... -
Estimation of trace element concentrations in the lunar magma ocean using mineral- and metal-silicate melt partition coefficients
(The Meteoritical Society, 2015)Abstract–This study uses experimentally determined plagioclase-melt D values to estimate the trace element concentrations of Sr, Hf, Ga, W, Mo, Ru, Pd, Au, Ni, and Co in a crystallizing lunar ... -
Meter-Scale Chemical and Isotopic Heterogeneities in the Oceanic Mantle, Leka Ophiolite Complex, Norway
(Oxford, 2021-07-13)Mantle peridotites from three 3 x 3-meter grids sampled at kilometer distances from one another in the ca. 497 Ma Leka Ophiolite Complex (LOC), Norway, are examined to investigate the chemical and isotopic nature of oceanic ... -
Evaluating the ecology of Spinosaurus: Shoreline generalist or aquatic pursuit specialist?
(Coquina Press, 2021-01)The giant theropod Spinosaurus was an unusual animal and highly derived in many ways, and interpretations of its ecology remain controversial. Recent papers have added considerable knowledge of the anatomy of the genus ... -
Lower rotational inertia and larger leg muscles indicate more rapid turns in tyrannosaurids than in other large theropods
(2019-02-21)Synopsis Tyrannosaurid dinosaurs had large preserved leg muscle attachments and low rotational inertia relative to their body mass, indicating that they could turn more quickly than other large theropods. Methods To ...
