Hydromechanical behaviour of a surge-type glacier; Trapridge Glacier, Yukon Territory, Canada

Subglacial hydrological and mechanical processes play a critical role in determining the flow characteristics and stability of glaciers and ice sheets, but our understanding of these processes remains incomplete. Instrument and modelling studies of conditions beneath Trapridge Glacier, a small surge-type glacier in the St. Elias mountains, Yukon, yield additional insight into subglacial hydromechanical behaviour. High-pressure pulses in the subglacial drainage system are indicated by sudden offsets in measured pressure and result from damage to the pressure sensor measurement diaphragm. Laboratory and modelling studies confirm that pressures significantly above the transducer rating produce offsets comparable to those observed in field records. Instrument records suggest that high-pressure pulses are generated by abrupt glacier motion that compresses or dilates the subglacial hydraulic system. Analysis of instrument records taken during summer 1995 reveals that a series of hydromechanical events occurred following the establishment of a subglacial drainage system. Pressure fluctuations in this drainage system weakened a basal region that was acting as a pinning point, resulting in three episodes of strong basal motion. A simple hydromechanical model of basal processes acting beneath a softbedded alpine glacier was developed. In this model, the glacier bed is divided into three regions: softbedded and hydraulically-connected to the subglacial drainage system, soft-bedded and unconnected, and hard-bedded. Each basal region is modelled as a one-dimensional column. The time evolution of pore-water pressure, till dilatancy, sediment deformation and glacier sliding is calculated in soft-bedded regions; hard-bedded regions are considered rigid and impermeable. The regions are coupled by a simple ice-dynamics model. Sediment deformation is calculated for four till flow laws: linear-viscous, nonlinear-viscous, nonlinear- Bingham and Coulomb-plastic. Modelled pore-water pressure profiles, deformation profiles, basal shear stress and instrument responses are presented for the four flow laws. Comparison of synthetic and field instrument responses suggests that till behaviour is best represented as Coulomb-plastic.

Structural evolution of the Ketza River gold deposit

Two phases of ductile deformation, followed by thrusting and extension, affected the Ketza River Mine area. D1 produced large scale E-W trending folds (F1) with upright axial planes, and a pronounced axial planar foliation (S1). Large scale F2 folds have E-W axial trends coincident with those of F1, and moderately NNE-dipping axial planes and axial planar foliation (S2). D2 also produced small-scale, SSW-verging folding of S1 along E-W to NW trending axes.

Shallowly SSW-dipping thrust fault surfaces, and regional analogies suggest NE-directed thrusting (D3). An extensional event (D4) coincided with the timing of mineralization. Normal displacement along the S-dipping Peel Fault resulted in the separation of the map area into two stratigraphic domains:: predominantly unit 1a argillites exposed in the northern domain, and predominantly unit 1d limestones exposed on the southern domain. Subsequent to the development of the Peel Fault, a series of NNW trending listric and planar normal faults separated the map area into four structural domains:: 1) western half-graben; 2) central horst; 3) eastern graben; and 4) eastern planar high-angle fault blocks. Axial-planar extensional veins developed along drag folds associated with graben-forming faults are intimately associated with manto-style orebodies. Several orebodies extend from listric normal faults in the preferentially mineralized limestone facies, suggesting that D4 faults were primary conduits for mineralizing fluids. There is no regional equivalent of D4. D4 may represent brittle response to the emplacement of a pluton.

The last deformation event (D5) produced a reverse fault that conceals the eastern portion of the Peel Fault (D4). D5 was a local, post-mineralization event that produced little dismemberment of the orebodies.

Petrology & geology of high level rhyolite intrusives of the Skukum area, 105 D SW, Yukon Territory

The Skukum area is located 58 km south-southwest of Whitehorse. It is an elliptical area of volcanic rocks, Tertiary in age, and surrounded by hypabyssal rhyolite intrusives. Field and petrographic evidence, fluorite and tourmaline stockwork, breccia pipes, roof pendants, miarolitic cavities and spherulites in the nine Skukum rhyolites suggest that they were emplaced at a high level. The intrusives vary in composition from rhyolite to dacite. The variation in texture within and between the intrusives can be explained by different rates of crystallization, temperature differences and compositional variability.

Chemical data are in accord with the expected trends in a cogenetic suite of igneous rocks. Relatively low CaO and MgO, high SiO2 and anomalously low Sr concentrations indicate that the rhyolites were formed from a highly differentiated magma. Sr and Ba versus Al2O3 plots show that both k-feldspar and plagioclase were important fractionating phases. Rare earth element data further support this conclusion and also suggest that some accessory phase(s), such as monazite, allanite or fluorite help control the rare earth element behaviour. Partial melting of an already depleted source rock with residual plagioclase can also explain the patterns.

The Bennett Lake ring and associated dykes are petrographically and chemically similar to the Skukum intrusives. However, Zr and TiO2 are present in higher concentrations in the Bennett Lake complex, indicating that they were derived by a slightly different fractionation process.

Early Jurassic porphyry(?) copper (-gold) deposits at Minto and Williams Creek, Carmacks Copper Belt, western Yukon

The Minto and Williams Creek copper (-gold) deposits in western Yukon are hosted by variably deformed Early Jurassic (198-197 Ma; U-Pb) plutonic rocks and to a lesser extent strongly metamorphosed supracrustal rocks. These rocks are pendants and schlieren within slightly younger (197 Ma; U-Pb), intermediate-composition intrusive phases of the Granite Batholith. Chalcopyrite and bornite are disseminated and also occur as stringers in these rocks. Alteration muscovite associated with late quartz-feldspar-epidote veins gives a 182 Ma Ar-Ar age. Geobarometry on postmineral intrusive phases in the area indicate that they were emplaced at a depth of >9 km. Hornblende geochemical studies of plutonic and meta-plutonic host rocks at Minto and Williams Creek indicate that they formed in a continental magmatic arc setting. Cu/Au ratios and field observations indicate that supergene mobility of copper was more extensive at Williams Creek than at Minto. Our results indicate that the two deposits represent variations on typical copper (-gold) porphyry deposits.

Preliminary investigations of emerald mineralization in the Regal Ridge area, Finlayson Lake district, southeastern Yukon

Emerald has recently been discovered in two areas in the northern Cordillera, the Lened area immediately east of the Yukon/NWT border and the Regal Ridge property in the Finlayson Lake district of southeastern Yukon; potential for additional emerald occurrences is thought to be very good. Preliminary results from investigations at Regal Ridge in 2002 reveal a continuum between typical biotite (± muscovite) quartz monzonite to quartz-rich, tourmaline-bearing granitic pegmatite and aplite (locally containing beryl) to quartz-tourmaline veins that either contain emerald or carry emerald in associated alteration envelopes. It is likely (but still unproven) that the chromium in emeralds at Regal Ridge is derived from the mafi c metavolcanic host rocks. Detailed petrographic examination of the veins and altered host rocks is aimed at constraining the composition and nature of the mineralizing fluids responsible for formation of the emeralds.

Gold mineralization in the upper Hyland River area: a non-magmatic origin

Gold occurrences in the upper Hyland River valley form a 50-km-long belt that is considered to be the easternmost portion of the Tombstone Gold Belt (TGB). Mineralization is thought to have a genetic association with nearby Cretaceous plutons, which were important in the formation of most mineralization in the TGB. However, an evaluation of the Hyland River occurrences indicates that evidence supporting an intrusion-related gold model is mostly lacking. Plutons and dykes do not occur in the vicinity of the gold occurrences; there are no obvious zones of hornfels; contact metamorphic minerals and skarns are mostly absent; there is no known mineral or metal zonation typical of intrusion-related systems; and aeromagnetic lows result from massive, variably altered quartz grit and conglomerate and not from unroofed `low-mag' intrusions. Mineralization consists of four types: 1) disseminated pyrite and arsenopyrite in altered grit; 2) quartz-arsenopyrite veins; 3) quartz-pyrite-galena veins; and, 4) massive arsenopyrite veins. Auriferous quartz veins have characteristics similar to orogenic gold veins, and thus potentially relate to regional metamorphism and large structural features.

Geology and mineralization of the Len intrusive-hosted gold prospect, McQuesten area, Yukon

The Len porphyry gold prospect is located 47 km north of Mayo, Yukon, in the Tombstone Suite intrusive belt. The area was explored as a Keno Hill-style silver prospect in the 1960s and 1970s. An arsenic-in-soil anomaly first identified in 1980 was followed up by soil geochemistry and excavator trenching in 1996. Multiple sheeted quartz-sulphide veins hosted in a previously unmapped granodiorite stock were discovered during the trenching program. A six-hole program of diamond drilling in 1997 encountered grades ranging up to 2.22 g/t gold across 18.6 m, and showed that gold mineralization is dominantly within, but not restricted to, the intrusive stock.

The Duke River fault, southwest Yukon: Preliminary examination of the relationships between Wrangellia and the Alexander terrane

The Duke River fault is a terrane-bounding structure that separates the Alexander terrane from Wrangellia in southwest Yukon. Detailed geological mapping and sampling of three key areas along the fault was completed in August 2009. In these areas, the fault juxtaposes multiply folded, pervasively foliated, greenschist facies rocks of the Alexander terrane against low-grade Wrangellian rocks that record only one phase of folding. Shear bands, fold orientations, rotated grains, lineations, mica fish and fault plane orientations indicate that the Alexander terrane has been thrust over Wrangellia. Preliminary 40Ar/39Ar ages from muscovite grains that may have been reset by motions along the Duke River fault or grown during faulting range from 90-104 Ma, suggesting that movement along the fault is at least as old as Cretaceous. Miocene felsic intrusions and Miocene to Pliocene crustal tuffs of the Wrangell lavas have been deformed by the Duke River fault, suggesting movement occurred as recently as the Pliocene
