I need to know 7 different ways.
Some tools used in mineral exploration: Remote Sensing (satellite imagery to find strucures and rocks lilely to contain mineral deposits) Geophysics (measuring small changes in natural phenomena to detect mineral deposits). Those in common use include magnetics, conductivity, gravity, radiometrics. Seismic (sound waves) to analyse sedimentary rocks when searching for oil and gas. Geochemistry: measuring metal content of soils and rocks to detect higher than normal levels which may indicate a mineral deposit. Geological mapping: looking at rocks and their relationships to find good targets for further exploration. Drilling: only way to truly test deeper mineral deposits: various types that either extract chips of rock or solid core of rock. Prospecting: working your way up a stream loking for concentrations of metals in gravels by panning: old school but still used!
Digging. je je. Some plants require a strong suplement of minerals for survive, if you see one of that, you are in a place that have that mineral. Of course this apply for iron Nq and some other single minerals, I don?t know about a plant that requires gold. Ho but if you are looking for calcium phosporus or something no mjetalic minerals, then this could be a usefull method You can use a matemnatical model, if you know that in some side are gold and in other side you also have that metal, the you can try to interpolate both sides fr see what do you have in the middle. The geologyst have some other metods, I think that they can identify the mineral oxide in the surface or througout the soil horizont. Also I saw once one of they using a sieve in a river, not for find gold but for identify the mountain composition, but i don?t know about that metods.
