Apr 01, 2015·FavorableAreas. 1. Probably themost favorablearea in which to prospect forgoldis one where the country rock is made up of surface flows, sills, dikes, and other intrusions of relatively fine grained, light colored, Tertiary igneous rocks such as rhyolite, trachyte, latite, phonolite, and andesite. 2.
Get PriceCalc-alkalic magmas are most favorable for the formation of giant porphyry copper deposits, although several of the largest systems are associated with high K calc-alkalic intrusions. The 25 largest gold-rich porphyry deposits are concentrated in the southwest Pacific and South America, with other occurrences in Eurasia, British Columbia, Alaska, and New South Wales.
A "mineraldeposit" is amineraloccurrence of sufficient size and grade that it might, under themost favorableof circumstances, be considered to have economic potential. An "oredeposit" is amineraldeposit that has been tested and is known to be of sufficient size, grade, and accessibility to be producible to yield a profit.

Therefore,small faults with slight displacementare the most favorable locations for ore deposits. Brittle quartzites make either clean breaks or shattered zones, whereas shales and many igneous rocks make tight fractures with much gouge, so they have a low permeability.

Pyroxene and garnet are the most important diagnostic minerals. Gold-bearing skarns are commonly the result of large-scale metasomatic transfer of components between hydrothermal fluids and predominately carbonate rocks. They are generally calcic exoskarns associated with intense retrograde hydrosilicate alteration.

(7) Zincminerals, often associated with lead deposits, are well known for their fluorescence. Zincoresoccurmostoften as cavity fillings or replacement bodies, which are found in limestones and dolomites, but can be found in many other rock types. Sphalerite is zinc’s mainore, which glows a bright orange color under short-wave UV light.
Although zones of disseminated sulfides are found in many places in this area, the contained copper and molybdenite is insufficient to form submarginalorebodies inmostplaces. One known exception is the Weezie claim on Silver Creek, where the rock in an area 200 by 240 feet contains disseminated molybdenum and copperminerals.
