Definitions and Basic Concepts
There are many definitions of geochemistry, but the definition made by Goldschmidt emphasis on two aspects, namely:
1. distribution in the earth element (description)
2. principles that govern the distribution of the above (interpretation)
This definition basically states that the geochemical study the number and distribution of chemical elements in minerals, ores, rock soil, water, and atmosphere. Not limited to the investigation of chemical elements as the smallest unit of the material, as well as the abundance and distribution of isotopes and the abundance and distribution of the atomic nucleus.
Specific geochemical exploration concentrated on measuring the abundance, distribution, and migration of ore elements or elements that are closely related to ore, with the aim of detecting ore deposits. In the narrower sense of exploration geochemistry is the systematic measurement of one or more trace elements in rocks, soils, active river sediments, vegetation, water, or gas, to obtain geochemical anomalies, namely the abnormal concentrations of certain elements that contrast against the environment (geochemical background ).
1.1 Basic Principles Exploration Geochemistry
Geochemical exploration basically consists of two methods:
1. Method using mechanical dispersion pattern applied to a relatively stable mineral in the earth's surface conditions (such as gold, platinum, kasiterit, chromite, rare earth minerals). Suitable for use in areas that restrict the climate conditions of chemical weathering.
2. Method based on pattern recognition of chemical dispersion. This pattern can be obtained either on the ore deposits that are not eroded or eroded, either obsolete or that are not obsolete.
This pattern is less evident as the mechanical dispersion pattern, because the elements that make up the dispersion pattern could be:
1. Have different mineralogy in sediments ore (example: serussyte and anglesite deposits formed by weathering Galena)
2. Can be dispersed in the solution (Cu2 + ions in the groundwater comes from sediment kalkopirite)
3. Be hidden in other minerals (eg Ni in serpentin and empung adjacent to sutu deposition pentlandit)
4. can be adsorb (eg Cu in clay or organic material in the stream can be supplied by groundwater through the sediment kalkopirit)
5. could join with organic material (eg Cu in or khewan)
