Mineralization of organogenic ammonium in the monterey formation santa maria and san joaquin basins, california, usa
TL;DR: Inorganic fixed-ammonium (NH4) contents as high as 0.28 wt% were measured in organicrich, quartz-grade siliceous rocks of the Miocene Monterey Formation from the Santa Maria and San Joaquin basins, California as mentioned in this paper.
Journal ArticleDOI
Isotopic and chemical compositions of bentonites as paleoenvironmental indicators of the Cretaceous Western Interior Seaway
TL;DR: In this paper, the chemical and isotopic data indicate that the variations in mineralogy and alteration of the bentonites result from widely disparate depositional environments and the alteration of smectites by interaction with basinal brines.

Chemical and mineralogical characterization of historic mortars from the Santa Eulalia de Bóveda temple, NW Spain
Jorge Sanjurjo-Sánchez,M. J. Trindade,Rebeca Blanco-Rotea,R. Benavides Garcia,D. Fernández Mosquera,Christopher Ian Burbidge,Maria Isabel Prudêncio,Maria Isabel Dias +7 more
TL;DR: In this paper, X-ray diffraction and neutron activation analysis of mortars from the Santa Eulalia de Boveda temple (NW Spain) has been performed to evaluate possible correlations with the various identified stages along historical periods of construction.

Cielab color parameters and their relationship to soil characteristics in Mediterranean red soils
TL;DR: In this article, the relationship between these color parameters and other soil characteristics was examined, including texture, organic carbon content, cation exchange capacity, and mineralogical composition in fine earth and clay fraction were correlated most strongly with soil color.
Journal ArticleDOI
Geochemistry and mineralogy of travertine deposits of the SW flank of Mt. Etna (Italy): Relationships with past volcanic and degassing activity
TL;DR: In this paper, the chemical, mineralogical and isotopic compositions of travertines in the lower SW flank of Mt. Etna were studied for their mapping, as well as for their chemical and mineralogical compositions.
