The Rawhide and Buckskin Mountains are a well-known detachment fault district hosting polymetallic shear zone and replacement deposits. Posted by The south domain is a supradetachment basin controlled by the Cañada David detachment fault. Silicon is located in the Bare Mountain district where gold was discovered in 1905. Dagwalala is distinctive, as the host rock is interpreted to be a talus breccia thought to have formed through slippage on the Detachment Fault Zone. The NNE-trending Linglong Metamorphic Core Complex hosts the majority of the gold deposits in the Jiaodong Peninsula of eastern China. and Welty, 1986). The claims are 100% owned by IMC International Mining Corp.  Carlin-type, detachment-fault-related gold, Fe-oxide Cu–Au (IOCG) and gold in carbonate replacement and manganese deposits are some of the potential deposit types (Fig. Nugget Hill Mining Claim (NH) The NH claim consist of one (1) unpatented lode claim covering 20.66 acres on federal land managed by the U.S. Bureau of Land Management. The Mockingbird Project involves an important new type of Arizona gold deposit, called a "detachment fault" deposit. One of several gold-silver bearing detachment faults in Arizona. The NH claim is in the Santa Maria Mining District in Mohave County, Arizona which is known for its copper, manganese, gold, and silver deposits. Gjeol. The ores are zones of intensive silicification and brecciation synchronous with detachment faulting. The 377-page book describes gold deposits, ... Then there are the detachment fault gold deposits that extend across Arizona from the northwest to the northeast. Gold is essentially limited to this late-stage pyrite or, uncommonly, has been remobilized during supergene alteration. VEIN DEPOSITS Earth Science. Argon thermochronology suggests that the granite had cooled to 400. 6). North Rawhide: Upper plate gold, silver and copper deposit. Ma Linglong granite in the footwall of the Linglong detachment fault. The property has a regional setting typical of detachment fault gold deposits and has geological, mining and metallurgical similarities to the Mesquite Mine in California. Gold mineralization is located in: (1) a massive, tabular ore body above the detachment fault; and (2) open spacefilling ores along predominantly east–west oriented listric faults. Most vein deposits occur in fault or fissure openings or in shear zones within country rock a vein deposit is sometimes referred to as a metalliferous lode deposit a great many valuable ore minerals, such as native gold or silver or metal sulphides, are deposited along with gangue minerals, mainly quartz andor calcite, in a vein structure Badwater Region Detachment Fault BW1. Shear zones form a continuum of geological structures, ranging from brittle shear zones (or faults) via brittle–ductile shear zones (or semibrittle shear zones), ductile–brittle to ductile shear zones. Properties. Two seismic profiles indicate the detachment fault dips 17°–20° west, has a minimum of 10.1 km of slip, and accumulates a sedimentary wedge more than 2.5 km thick in the west-central part of this basin domain. Tokachka fault dips gently (10- The fault-localized feeders, which are inferred originally to have underlain the high sulfidation deposits, were detached from them by the low-angle faults.All ore exploited from the high sulfidation deposits underwent supergene sulfide oxidation during weathering, which commenced after detachment faulting had ceased and was ongoing at 10 Ma. These unusual gold deposits are mostly overlooked, and they appear to be abundant! Gold deposits of Turkey, as well as other mineral deposits, are mainly associated with Late Mesozoic and Tertiary rocks (Fig. Gold mineralization is located in: (1) a massive, tabular ore body above the detachment fault; and (2) open spacefilling ores along predominantly east–west oriented listric faults. Detachment-fault deposits contain fractures and thick, irregu- … The gold is reportedly very fine- … 33. Precious metal deposits in the Southwest Nevada Volcanic Field (SWNVF) have combined production and reserves of greater than 60 t of Au and 150 t of silver (Castor and Weiss, 1992). Former Phelps Dodge project. Shk. Location/Access: (36o 02.757’N, 116o 45.636’W) 10.2 miles north of Ashford Mill and 16.5 miles south of Badwater.Although this site is located within yards of the main highway, there are no signs, parking areas or other hints of its location. ... Silicified Ov black shale from megabreccia below detachment fault 1.495 ppm). The deposit provides excellent exposures of the hangingwall, footwall, and detachment itself, marked by mylonitic Detachment fault deposits were first recognized as a separate form of gold deposit in the 1980’s. gold deposit is situated 5 km southeast of Krumovgrad town, Eastern Rhodopes. McCracken Gold: Gold with silver and copper in breccia zone adjacent to one of Arizona’s historic silver producers. The dominant structure of the range is the Plomosa detachment fault, a low-angle normal fault that separates a single tilted footwall block from a highly extended hanging wall with diverse stratigraphy and complex structure. Climax Mine Claim (CM 3) The CM3 claim consist of one (1) unpatented lode claim covering 20.66 acres on federal land managed by the U.S. Bureau of Land Management. 2a), is situated in the central part of the Linglong detachment fault that defines the eastern edge of the Linglong MCC. °C by 143. A shear zone is a zone of strong deformation (with a high strain rate) surrounded by rocks with a lower state of finite strain.It is characterised by a length to width ratio of more than 5:1. The property has a regional setting typical of detachment fault gold deposits and has geological, mining and metallurgical similarities to the … A rational geological classification of the commonly recognized lode gold deposits is feasible if it is based on the geological settings of the deposits, host rocks, nature of mineralization and geoche m-ical signature. Graph showing tonnages of laterite-saprolite Au deposits 50 34. Then there are the detachment fault gold deposits that extend across Arizona from the northwest to the northeast. Many of the deposits are hosted by the 163-155. Mineral deposits related to detachment faults formed within this tectonic setting and were the result of hydrothermal ascent of basin brines along detachment faults (Wilkins and others, 1986). The area of our claims has numerous high-grade outcroppings with spectacular, highly mineralized copper oxide mineralization, sulphides, and gold mineralization. 1.5. Mockingbird: Gold and silver deposit related to detachment fault. The best example of an Arizona detachment gold deposit is probably the “Copperstone” Gold deposit, which like “Ester Basin” is in the highly extended Western Arizona terrane, as well as in the “Walker Lane” gold trend. This N-NW fabric is the same structural control to gold mineralization in productive Carlin-type gold deposits along the Cortez gold belt, including in the Pipeline - Cortez Hills - Goldrush district (+50 million ounces). Figure 1. Nevada. The two principal deposits at Wapolu consist wholly of oxide ore (Dagwalala), or predominantly of oxide ore with subordinate underlying primary ore (Didigayagaya). detachment faults near Wapolu at the north-western part of Fergusson Island. Epithermal deposits can be distinguished from detachment-fault-related deposits by their characteristic ore mineralogy, alteration minerals and patterns, geochemical signatures, and fluid-inclusion compositions, as described in the deposit model for hot spring Au-Ag (Berger, 1986b). These unusual gold deposits are mostly overlooked, and they appear to be abundant! Relatively little is known about the details of the formation of the gold deposits or details of the controls on mineralisation at Wapolu. The Mineral Ridge gold deposits are located on the northeast flank of the Silver Peak Mountain Range. The N200 t Au Xiadian gold deposit, which is located 15 km to the southwest of the Dayingezhuang deposit (Fig. Graph showing gold grades of laterite-saprolite Au deposits 51 35. ±. The northwest Jiaodong metallogenic belt mainly develops large-scale fracture-altered style gold deposits, which are controlled by NE-NNE trending gently inclined detachment faults, represented by the Sanshandao fault, the Jiaojia fault and the Zhaoping fault.
