classification of ores

Classification of Ore Deposits

Descriptive classifications could be very tedious as each ore body has its own unique properties Classifications based on the morphology of the ore body could be quite useful but have a tendency to mix apples with oranges two ore bodies of similar shapes may be very different in type of ore texture origin temperature of formation etc...
