Surficial Geology of Alligator Lake map

Between the Cretaceous granites (Hake Batholith on the west; Cassiar Batholith to the east) are three belts of metamorphic rocks, collectively part of Yukon-Tanana Terrane (Mortensen, 1992). These are remnants of oceanic and continental volcanic arcs, and marginal basin sediments of Early to...

A map of the residual total magnetic field derived from data acquired by Goldak Airborne Surveys during the period of November 19, 2008 to February 19, 2009. Data were recorded using a split-beam cesium vapour magnetometer mounted in the tail boom of a Piper Navajo aircraft.

Geological map of Faro (NTS 105K/3 NE) and Mount Mye (NTS 105K/6 SE), Yukon (1:25 000 scale)

Surficial geological map (1:50 000 scale) and till geochemistry (copper, lead, zinc, gold, silver, chromium, nickel, mercury, antimony, arsenic) of Weasel Lake area, central Yukon (NTS 105 G/13).

The world production of diamonds in 1990 was more than 100 million carats (metric carats, or CM; 1 carat = 0.2 grams), compared to 75 million in 1985, and 15 million in 1950. This represents a more than 14% per year growth rate. The value of 1990 production was about US$4.5 billion (1992 US$),...

A placer mining and exploration compilation of NTS map sheets 115 I and 115 J/K, southern Yukon Territory, Canada. This compilation includes the location, history and previous work, description of bedrock geology, surficial geology and mineralization, as well as lists of related references....

Glacial limits and ice-flow map (1:250 000 scale) of Mayo area, central Yukon (parts of NTS 115 P northeast, 116 A southeast, 105 M northwest and 106 D southwest).

Yukon Exploration and Geology 2007

This map of the first vertical derivative of the magnetic field was derived from data acquired during an aeromagnetic survey carried out by Fugro Airborne Surveys during the period April 17, 2006 to August 26, 2007. The data were recorded using a split-beam cesium vapour magnetometer (sensitivity...

This map was compiled from data obtained as a result of an aeromagnetic survey carried out by Fugro Airborne Surveys using a Cessna Caravan (registration C-FZLK) aircraft. A 0.005 nT sensitivity split-beam cesium vapour magnetometer was mounted in the tail boom of the survey aircraft. The survey...

Yukon Exploration 1985-1986 provides details of exploration and mining activity in the Yukon, including placer mining. It discusses the geology of Yukon mineral deposits and mineral districts under active investigation and provides a summary of exploration work done by mineral exploration...

Unconsolidated sediments in the Mount Nansen area can be subdivided into eight clastic facies: 1)clay-rich diamicton; 2) massive/stratified silt/clay; 3) massive/disorganized pebbly sand/sand; 4) stratified pebbly sand/sand; 5) disorganized muddy gravel; 6) massive/stratified sandy gravel; 7)...

Placer deposits in the Mayo area occur in a wide variety of geomorphic settings, including alluvial fans, gulch gravel, valley-bottoms (alluvial plains), and bedrock terraces (bench gravel), which have been variably buried and reworked by glaciofluvial processes. Placer gold also occurs in...

Bouger gravity anomaly of the northern Aishihik Lake area, Yukon (parts of NTS 115H, I and G)

Map of the first vertical derivative of the magnetic field derived from data acquired during an aeromagnetic survey carried out by Goldak Airborne Surveys from November 19, 2008 to February 19, 2009. The data were recorded using a split-beam cesium vapour magnetometer mounted in the tail boom of...

Preliminary geological map (1:25 000 scale) of the Mt. Vermillion area, southern Yukon (parts of 105 G/5 and 105 G/6) including geological cross-sections and mineral occurrences.

The central Yukon Territory has a number of favourable placer deposit settings due to its unique history of multiple glaciations, active stream sedimentation in association with proglacial outwash settings and terrain which has remained unglaciated (Morison, 1989 a,b). Placer gold was found along...

Open File 2001-12(D) (also known as GSC Open File 4016) represents the second in a series of re-formatted Yukon National Geochemical Reconnaissance Open Files. Data were originally released in 1982 as GSC Open File 868. Re-analysis by INAA was carried out and released in 1999 as GSC Open File...
