Abstract One of the prime requirements for effective study of environmental geochemistry in relation to health is the production of multi-element atlases showing the distribution of the elements on the regional scale. The choice of method for compiling such atlases can vary according to a number of geological, environmental and other ...

Geochemical mapping in Jamaica
Environmental Geochemistry and Health, 1996A high-precision regional geochemical data base of Jamaica is being developed as a basis for a wide variety of economic and environmental applications. These include pollution studies, resource identification and management, agriculture, land use, and the relationship between geochemistry and the health of crops, animals, and man.

Geochemical Scavenging of Strontium
Science, 1958Crandallite, an abundant mineral belonging to the alunite structure type, is a geochemical host for ordinary strontium in the soil profile and the deeper ground-water circulation. It may be useful in the scavenging or storage of the radioisotopes of strontium and certain other elements.

Low-density geochemical mapping and the robustness of geochemical patterns
Geochemistry: Exploration, Environment, Analysis, 2008Geochemical mapping of entire continents and, ultimately, the world is still a challenge for applied geochemists. At sample densities traditionally used for geochemical exploration (1 site per 1–25 km 2 ), geochemical mapping of whole continents is logistically extremely demanding and tremendously expensive.

Geochemical Exploration for Petroleum
Science, 1985Geochemical methods used in exploring for oil and natural gas are based on the premise that hydrocarbons migrate upward from subsurface petroleum accumulations and produce anomalous patterns near the surface. Geochemical exploration techniques are both direct or indirect.

Symposium on Geochemical Exploration Geochemical Prospecting for Petroleum
AAPG Bulletin, 1940ABSTRACT Case treatments are presented or pointed to in the literature which include examples of prospecting by refraction fans, a geoelectrical method (Eltran), and chemical analyses of soils, soil gases, and ground waters. These type geophysical and geochemical anomalies are associated with producing structure ...

Geochemical Modeling of Reaction Paths and Geochemical Reaction Networks
Reviews in Mineralogy and Geochemistry, 2009From the discussions in previous chapters, we can see that in order to understand the kinetics of dissolution and precipitation reactions, we really need to understand geochemical reaction networks. The previous chapters have depicted a complex picture of the details of chemical reactions and kinetics.

Geochemical tracers of biomineralization processes
Goldschmidt2024 abstractsBiominerals play a central role in Earth's past, present and future climate, but there are major gaps in our understanding of how they form. In this chapter, we consider how the geochemistry of calcium carbonate biominerals may be used to interrogate the mechanisms that produce them.
