Geochemical exploration

The determination of cesium in minerals can be accompHshed by x-ray fluorescence spectrometry or for low ranges associated with geochemical exploration, by atomic absorption, using comparative standards. For low levels of cesium in medical research, the proton induced x-ray emission technique has been developed (40).

Groundwater as a medium for geochemical exploration in peatlands Jamil A. Sader1, Keiko Hattori1, Stewart M. Hamilton2... 

Our results indicate that peat groundwater can be an effective medium for surficial geochemical exploration. The dilute, acidic peat groundwaters contrast well with groundwaters that have interacted with kimberlite. 

The main conclusion drawn from this study is that hydrocarbon- and fixed gas-based geochemical exploration methods in the Paradox Basin are cost-effective tools for pre-screening large areas to focus subsequent lease acquisition and seismic surveys for oil and gas exploration. Heavy metal anomalies are more difficult to link with the reservoir.
