Increasing the spatial resolution of Laser Ablation Inductively Coupled Plasma Mass
Spectrometry (LA-ICP-MS) is a challenge in microanalysis of geological samples. Smaller …

Geochemical analysis of obsidian artifacts from the Sinbuk Paleolithic site in southwestern
Korea has been performed by laser ablation ICP-MS (LA-ICP-MS). As a result of this study …

The provenance of obsidian artifacts from the Wolseongdong Paleolithic site in Korea has
hitherto been uncertain. A previous study was unable to identify the source despite the …

Cenozoic volcanic rocks were recently discovered during full-coring kilometer-scale major
scientific drilling in the Xisha Islands, northwestern South China Sea. A systematic …

We report the analysis by LA-ICP-MS of 204 obsidian artifacts obtained from museum
archives in the Republic of Korea. They were recovered at Bronze Age, Neolithic and …

Glass beads that remain after measuring major element compositions using XRF can also
be used to measure trace element compositions using laser ablation inductively coupled …

Compositions of clinopyroxenes and spinels from the ocean/continent boundary of the
Cameroon Line are presented. The spinels occur as minute inclusions in olivine …

New petrographic, geochemical, and isotopic (Sr, Nd, and δ 18 О) data on olivine and
pyroxene phenocrysts provide constraints on the composition and crustal evolution of …

Many medical devices contain metals that interface with the body. Additionally, embedded
metal fragments from military wounds are typically not removed, to avoid the risk of morbidity …
