CHAPTER 4 PORPHYRY DEPOSITS British ColumbiaExploration of Porphyry Copper Deposits

CHAPTER 4 PORPHYRY DEPOSITS CLASSIFICATION AND GEOLOGICAL CHARACTERISTICS The development of the first porphyry copper and molybdenum deposits in British Columbia in the s and s had a profound effect on the mining commu nity Newell et al It was recognized that large low grade deposits could be mined economically by open pit methods through economies of So this gives us a start in deciding where to focus our exploration because of the extensive subduction during the tertiary ie in the last 65 000 000 years many porphyry deposits are of this age in other words porphyries are relatively young by geological standards just put that comment in context although 65 million years sounds a long time

Porphyry Copper Systems GeoScienceWorldPorphyry geological feature Britannica

Abstract Porphyry Cu systems host some of the most widely distributed mineralization types at convergent plate boundaries including porphyry deposits centered on intrusions skarn carbonate replacement and sediment hosted Au deposits in increasingly peripheral locations and superjacent high and intermediate sulfidation epithermal depositsAmong the most distinctive hydrothermal deposits is a class known as porphyry copper deposits so called because they are invariably associated with igneous intrusives that are porphyritic meaning the rock is a mixture of coarse and fine mineral grains
