Quartz is an important mineral element and the most abundant rock-forming mineral that controls the mineralogy of a reservoir. At the surface, quartz is more stable than most other rock minerals because it is made up of interlocking silica that makes it quite resistant to mechanical weathering. Quartz abundance is an indication of mineralization in many metal deposits therefore.

Satellite imagery is vital for early exploration and is typically one of the first data types acquired by anyone working in a new area. When combined with field mapping and geophysics it becomes a very efficient way to gain geological understanding. Today we can obtain imagery from a wide variety of satellite systems like Landsat, WorldView, SPOT, RapidEye and EROS, amongst others.
