... on bedding were commonly subsumed within younger D 3 structures. Thus D 3 disguises the presence of D (sub 2.5) , except in relatively rare locations where D 2 folds were isoclinal, such as in the Tommy Creek block and on the northern end of the Snake Creek anticline southeast of Cloncurry, and northwest...

... Abstract The Cripple Creek district is known for its low-sulfide gold-telluride vein systems of great vertical range (~1,OOOm) with virtually no change in ore grade; however, in the last 10 years shallow, low-grade, bulk-tonnage deposits have been recognized and developed. The deposits...

... of different settings. It is somewhat surprising, given the economic prominence of the Cripple Creek district, that it has escaped such attention. This is probably related to two main factors. First, in many types of hydrothermal gold deposits, quartz veins are common, and they offer an ideal sampling medium...

...Dean G. Heitt; W. Warren Dunbar; Tommy B. Thompson; Robert G. Jackson Abstract Deep Star is a high-grade Carlin-type gold deposit located in the northern part of the Carlin trend. The deposit averages 34.0 g/t Au and by year end 2000 had produced 37.8 t (1,217,000 oz) gold with a remaining reserve...

..., cinnabar, quartz and illite from the Carlin mine, although considerable gold could not be accounted for. Arehart et al. (1993) showed that much of this “invisible” gold at Post/Betze and Gold Quarry is in As-rich growth zones in pyrite, possibly in solid solution. At Twin Creeks, we have observed mat...
