The Mid - Cretaceous Rocky Ridge Formation - A New Target for Subaqueous Hot - Spring Deposits ( Eskay Creek - Type ) in Central British Columbia ?

چکیده
The Skeena Arch project was initiated in the 2000 field season as a follow up to work completed as part of the Nechako NATMAP project (MacIntyre and Struik, 1999). The main objective of this project is to define areas that have a high potent ia l for the discovery of volcanogenic massive sulphide and/or subaqueous hot spring deposits (Eskay Creek type) along the trend of the Skeena Arch, in central British Columbia. In this area favourable host rocks for these deposit types occur in two separate geologic units Lower to Middle Jurassic submarine volcanic rocks of the Hazelton Group and the mid-Cretaceous Rocky Ridge Formation of the Skeena Group. The latter represents a stratigraphic package whose potential was only identified during the recently completed Nechako NATMAP project.

The recognition of remnants of large cauldron subsidence complexes along the trend of the Skeena Arch first occurred in the Tahtsa Lake area (MacIntyre, 1985). In subsequent years, evidence for other large subsidence complexes was documented in the Rocher DeBoule, Babine Mountains, Buck Creek and Babine Lake areas (MacIntyre, 2001; Church and Barakso, 1990). Originally all of these structures w...

The Eskay Creek gold-silver mine, located in northwest British Columbia, is the highest-grade precious-metal volcanogenic massive sulphide deposit in the world. The mining industry continues to spend more than $2 million each year on exploration for similar deposits in the area. The geologic setting at the minesite is well studied, but large tracts in north-central British Columbia require more...

The Eskay Creek gold-silver mine, located in northwest British Columbia, is an unusually high-grade ore deposit. The mining industry continues to spend more than $2 million each year on exploration for similar deposits in the area. The geologic setting at the minesite is well studied, but large tracts in north-central British Columbia require more detailed surveys to determine if favourable sit...

Porphyry Cu and epithermal deposits are spatially and temporally related to specific volcanic and plutonic rocks emplaced during the formation of long-lived magmatic arcs formed along convergent plate boundaries (e.g., Sillitoe, 1972; Sutherland Brown, 1976; Titley, 1982; Sawkins, 1990; Bissig et al., 2003). Recognizing the presence, types of deposits, and age of the mineralized volcanoplutonic...

In southeastern British Columbia many inhusive suites lack conclusive radiometric age dates. The purpose of this BSc. project is to study three of the intrusions in the Purcell Mountain Range and provide uranium-lead geochronological results on two of these to refme the igneous magmatic history of the region. The White Creek Batholith (WCB) and the Greenland Creek Stock (GCS) are located approx...
