Geophysics is good for determining areas of low reflectivity of a lithology composition change, and geochemistry is good for the analysis of major RRE that are present allowing an indication into the composition and magma evolution. Field observations are always good for determining a rough size and orientation of the mama bodies and also helps you understand the composition, structures and textures of the magma body.]]> 2018-10-15 20:09:48 UTC https://padlet.com/rvi/lfovjuyo9c1h/wish/293051811 https://padlet.com/rvi/lfovjuyo9c1h/wish/293053729 Geophysical surveys such as gravity surveys would likely play a key part in the exploration of magma bodies. Geochemistry would also be helpful through analysing the mineralogy of extruded or country rocks to determine the presence of thermal alteration, fluid inclusions or high temperature minerals.
