Chemical Constitution of Secondary Abnormalities

The chemical constitution of a secondary abnormality does not directly reflect on the chemical behavior of a subjacent deposit but it is the result of the following phenomenon: 

• Oxidation conditions and mobility
• Presence of the traps

Therefore, it is important to pay attention and not grab on to immediate conclusions on the deposit seeing only the para-genesis anomalous. The most used means of getting close are then the floor samples, sediments of the river and the rocks, but there are also other types, used in certain particular cases which are:

• Hydrogeology: through a water analysis, however it has the problem of an analytical threshold. It is generally used for flour and uranium.
• Phytogeochemical: through the analysis of the ashes of certain vegetables.
• Analysis of the concentrates of the pans: in case the prospection is oriented towards certain metallic minerals.

In the development of this site, we will not be treating arguments from the theoretic point of view (which is done by geochemistry), but rather the practice application of the different methods.
