Inclusiones Fluidas y Metalogenia del Depósito Epitermal Ag/Au del. The Tertiary Mt. Skukum gold - silver epithermal vein deposit occurs 65 km southwest of Whitehorse in the Yukon Territory. Veins are hosted by a sequence of nearly flat-lying Eocene Skukum Group andesitic volcanic rocks of the Mt. Skukum Volcanic Complex, part of the Sloko Volcanic Province which unconformably overlies these intrusive complexes as well as .

Interpcetation of fluid inclusion gas data depends heavily upon a detailed knowledge of mineral and fluid inclusion paragenesis, and the element of rel- ative time in vein mineral depositional by: Recent advances in instrumentation now permit quantitative analysis of gas species from individual fluid inclusions.
Fluid inclusion gas data can be applied to minerals exploration empirically to establish chemical (gas composition) signatures of the ore fluids, and conceptually through the development of genetic models of ore formation from a framework of integrated.

Within each growth zone, however, the composition of the fluids remained constant. The base of a distinctive orange-brown growth zone marks a sharp.

Garrels ( - ). 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.
Successful exploration for mineral deposits requires tools that the explorationist can use to distinguish between targets with high potential for mineralization and those with lower economic potential. In this study, we describe a technique based on gangue mineral textures and fluid inclusion characteristics that has been applied to identify an area of high potential for gold Cited by: The data from fluid inclusion study in the Th-salinity plot reveal the presence of three fluid inclusion groups including: 1.

There are characteristic mineral textures and assemblages associated with epithermal deposits (Lindgren, ; Sillitoe, ; Hedenquist et al.,and references therein), and coupled with fluid inclusion data, they indicate that most epithermal deposits form in a temperature range of about ° to ° C.

Bodnar, 4 Stephen E. Laubach, 5 Stephen P. Becker 6. At ambient temperatures, cristobalite is tetragonal, and specimens from volcanic environments are paramorphs of cubic β-Cristobalite or high-cristobalite (stable above °C), still showing the initially cubic crystal morphology.
To distinguish it from the high-temperature cubic type, tetragonal cristobalite is also called α-cristobalite or. The Antevs Library Online Author Title Catalog The catalog includes nearly titles.
