Ore forming processes ~ Learning Geology

Weathering process can also provide metals to ores which are produced by other processes. Disseminated deposits contain metals but are not economical to mine so ground water and rainfall weathers these metals. In some cases metals react to weathering instead of removal which creates a supergene ore rich in metals above low grade mineralization.
