Upper Triassic to Lower Cretaceous stratigraphic data for the Whitehorse trough in Yukon, extending approximately 650 km. The dataset describes the Laberge Group's formations, their lithology, and hydrocarbon source/reserve potential, compiled by the Government of Yukon. Last updated on 2026-04-17.
The Finlayson Lake district in Yukon contains over 30 Mt of volcanogenic massive sulphide mineralization. Preliminary fieldwork from 2017 logged seven drill holes intersecting stratigraphic hanging walls and footwalls of the Fyre Lake, Kudz Ze Kayah, and GP4F deposits. The stratigraphic results reveal laminated volcaniclastic rocks interbedded with clastic or intrusive rocks, reflecting changes in depositional environments from Late Devonian to Early Mississippian.
The Fifty Mile Creek area in west-central Yukon contains previously unrecognized glacial erosional and depositional landforms, including cirques and end moraines. These features, similar to those in the adjacent Yukon-Tanana uplands of Alaska, formed during the Eagle glaciation (>40 ka). Glaciation influenced runoff and terrace formation, with placer gold occurring along Fifty Mile Creek and its tributaries, as well as in the lower-level terraces.
A newly mapped area centred on the Boswell River in south-central Yukon contains penetratively deformed rocks of the Yukon-Tanana terrane and Semenof block, and unfoliated Jurassic-Cretaceous intrusions. The dataset likely contains geological observations and interpretations from the Government of Yukon, last updated in April 2026. It is divided into three structural panels by the Little Bear and Sidney Creek faults, which may define tectonic boundaries.
Government of Yukon research describes the structural and stratigraphic setting of Devonian bedded barite and sedimentary exhalative lead-zinc-silver-barite deposits near MacMillan Pass. The study details three parallel elongate domains within the MacMillan Fold Belt, each with distinctive deformation styles and Devonian strata. The dataset was last updated on April 17, 2026.
Geological data describes the origin and setting of anomalous arc magmatism in the Wrangell Volcanic Belt, Southwest Yukon. The dataset likely contains compositional and temporal trends for volcanic stratigraphy spanning 17.3 to 6.5 million years in the St. Clare Creek field. It was published by the Government of Yukon on the open_canada platform.
Yukon-Tanana Terrane in southwestern Frances Lake area consists of three distinct geological domains defined by thrust sheets and rock units. The Money/Jules Creek thrust sheet comprises chert, argillite, limestone, and meta-volcanic rocks, while a northeastern domain features Permian conglomerate. Volcanogenic massive sulphide prospects occur in volcanic arc rocks within the thrust sheet, indicating potential for new mineral deposits.
Preliminary results from 2026 assess lithogeochemical characteristics of meta-volcanic rocks in the Finlayson Lake region, Yukon. The dataset, provided by the Government of Yukon, categorizes rocks into suites based on their geochemical signatures, such as low Ti tholeiites and boninites, and identifies suites prospective for volcanogenic massive sulphide mineralization.
Regional mapping north and west of Faro aims to improve knowledge of the geologic history and elucidate host stratigraphy for precious and base-metal occurrences. The southern Tay Mountain area is underlain by metamorphosed lower Cambrian to Silurian Selwyn basin strata thrust over Silurian to Triassic rocks. The entire succession is intruded by mid-Cretaceous granitic rocks and deformed by folding and thrust faults.
The Hart River area in the southeastern Ogilvie Mountains of Yukon is underlain by two widespread geological successions. This dataset from the Government of Yukon provides revised stratigraphy and identifies seven specific exploration targets for sediment-hosted base metal deposits. It was last updated on April 17, 2026.
Gold Run Creek, southeast of Dawson City, Yukon, is the site of a pilot project to stabilize slope failure caused by placer mining. Laberge Environmental Services conducted a reconnaissance survey in July 2003, and several bioengineering structures, including retaining walls and a live willow flume, were installed in fall 2005. The dataset likely contains details of the site assessment and intervention.
216 Ma crystallization age suggests the Aishihik Batholith granodiorite formed in the Early Jurassic. The Government of Yukon provides geological analysis suggesting the batholith is allochthonous above a metamorphic terrane, with tectonic modification possibly occurring during Stikinia's collision with North America. Relationships and kinematic indicators are described, though the regional extent of a detachment remains conjectural.
Increased oil and gas exploration in Yukon drives seismic line cuts, which can cause environmental degradation. Studies in 2006 and 2007 in Eagle Plains and Peel Plateau provided information on recovery ecology. This 2026 study builds on those to illustrate ecological characteristics of seismic line recovery in the distinct, forested Southeast Yukon region.
CORMIX model simulations predict the dispersion of placer mining effluent in the Fortymile River and hypothetical streams. The study, likely conducted by the Government of Yukon, examines scenarios varying suspended solids concentration and effluent flow rate. A water quality objective of 12.5 mg/L suspended sediment was achieved rapidly downstream of a diffuser.
Government of Yukon data describes the geology of the Mount M'Clintock map area northeast of Whitehorse. It details sedimentary and volcanic rock units, plutonic suites, structural features like folds and faults, and potential mineral deposit types. The dataset was last updated on April 17, 2026.
Wrangellian volcanic and sedimentary rocks in southwest Yukon underwent multiple deformation phases from Late Triassic to Miocene time. Bedrock mapping completed within the White River area documents these events, including Late Jurassic-Early Cretaceous compression and Cretaceous-Miocene strike-slip faulting. The dataset is provided by the Government of Yukon and was last updated on April 17, 2026.
A geological report from the Government of Yukon details the stratigraphy and alteration of the White Channel gravel at Dago Hill in the Klondike area. The report describes gravel formations, their relationship to bedrock, and a study conducted in 1983 to investigate links between alteration zones and placer gold deposition. The dataset is available in HTML and PDF formats under the OGL-CA-2.0 license.
The Paleogene Sifton Range volcanic complex comprises a 900-meter thick succession of intermediate to evolved lava and pyroclastic rocks deposited in a half-graben. The Government of Yukon provides this geological description, which includes intrusive alkali-feldspar granites dated at 57.5 Ma and details on post-Eocene uplift. The dataset was last updated on April 17, 2026.
A 1996 integrated exploration program by Columbia Gold Mines Ltd. documented a volcanogenic massive sulphide deposit. The dataset describes the geological setting, mineralogy, and dimensions of copper-cobalt-gold mineralization in the Kona zone, hosted within metamorphosed rocks. It is published by the Government of Yukon.
The White Channel Gravel is the most important gold-bearing unit in the Klondike goldfields, reaching up to 46 meters thick. This dataset likely contains geological analysis and petrographic examination of samples from the Yukon, reinterpreted as weathering and diagenesis. It was published by the Government of Yukon and last updated in April 2026.
