Data Collection and Mapping
Data collection and mapping techniques include a broad array of methods used for collecting information about a geothermal area directly in the field. Surface mapping, shallow temperature probe surveys, and portable XRF/XRD analysis represent a valuable set of basic, cost effective tools for evaluating geothermal prospects. These methods can provide a geothermal exploration program with considerable information about a hydrothermal system prior to the application of expensive laboratory analysis or exploration drilling techniques.
- Powder diffraction is a scientific technique using X-ray, neutron, or electron diffraction on powder or microcrystalline samples for structural characterization of materials. An instrument dedicated to performing such powder measurements is called a powder diffractometer. Powder diffraction stands in contrast to single crystal diffraction techniques, which work best with a single, well-ordered crystal.
