Composition of the earth's upper mantle. I - Siderophile trace elements in ultramafic nodules
TL;DR: In this article, a comprehensive suite of ultramafic inclusions was collected as part of the Basaltic Volcanism Study Project and has been analyzed by instrument neutron activation analysis for major, minor, and some lithophile trace elements.

Rare earth element distribution in some hydrothermal minerals: evidence for crystallographic control
TL;DR: In this article, rare earth element (REE) abundances were measured by neutron activation analysis in anhydrite (CaSO4), barite (BaSO4, siderite (FeCO3) and galena (PbS).

Calcareous nannofossil assemblage changes across the Paleocene–Eocene Thermal Maximum: Evidence from a shelf setting
TL;DR: The response of calcareous nannoplankton to abrupt warming across the Paleocene/Eocene boundary as mentioned in this paper reflected a primary response to climatically induced parameters including increased continental runoff of fresh-water, global acidification of seawater, high sedimentation rates, and calcaous nanna assemblage turnover.

Contribution of metapelitic sediments to the composition, heat production, and seismic velocity of the lower crust of southern New Mexico, U.S.A.
TL;DR: Granulite and sillimanite-bearing quartzofeldspathic xenoliths were probably emplaced in the lower crust by tectonic underplating at a lower Proterozoic subduction zone as discussed by the authors.

Environmental geochemistry of a Kuroko-type massive sulfide deposit at the abandoned Valzinco mine, Virginia, USA
TL;DR: The abandoned Valzinco mine, which worked a steeply dipping Kuroko-type massive sulfide deposit in the Virginia Au-pyrite belt, contributed significant metal-laden acidmine drainage to the Knight's Branch watershed.
