Silicate-melt inclusions (MI) are small (-1 to 300 pum) blebs of silicate melt that are trapped
within igneous phenocrysts (Fig. 1). They are glassy or crystalline, and are found within both …

We define tephras and cryptotephras and their components (mainly ash-sized particles of
glass±crystals in distal deposits) and summarize the basis of tephrochronology as a …

We present new analytical data of major and trace elements for the geological MPI‐DING
glasses KL2‐G, ML3B‐G, StHs6/80‐G, GOR128‐G, GOR132‐G, BM90/21‐G, T1‐G, and …

This experimental study examines the effects of variable concentrations of dissolved H 2 O
on the compositions of silicate melts and their coexisting mineral assemblage of olivine+ …

Three methods of estimating H2O contents of geologic glasses are compared:(1) ion
microprobe analysis (secondary ion mass spectrometry),(2) Fourier-transform infrared …

Studies of early human settlement in alpine environments provide insights into human
physiological, genetic, and cultural adaptation potentials. Although Late and even Middle …

Two magnesium silicate hydrates (MSH) with structural magnesium/silicon ratios of
0.57±0.08 and 1.07±0.13 were synthesized at room temperature, with one year of synthesis …

With ever more challenging (T, p) environments for cementing applications in oil and gas
wells, there is a need to identify the fundamental mechanisms of fracture resistant oil well …

Melting experiments with and without added H2O on a model metagreywacke and a natural
metapelite demonstrate how pressure and H2O content control the compositions of melts …

Abstract The latest Cenozoic (< 6 Ma) ash beds in the western United States have been
intensively studied for several decades. The more widespread of these ash beds are well …
