Depositional Setting of Silver-Rich Quartz-Sulphate-Carbonate Deposits of the Upper Kitsault River Area, Northwest British Columbia
نویسنده
چکیده
The Upper Kitsault River area lies approximately 23 to 30 km north of Alice Arm, in the Skeena Mining Division, British Columbia. Mineral occurrences are of three principal types: copper and gold-rich quartz-chlorite stockwork deposits, silver-rich quartz-sulphate-carbonate deposits; and molybdenum-rich quartz stockwork deposits (Alldrick et al., 1987). The first two types are hosted by lower Jurassic volcanic and sedimentary strata, near the top of the Hazelton volcanic arc sequence (Alldrick et al., 1987; Godwin et al., 1991). The third is considerably younger and is associated with a suite of Eocene quartz monzonite intrusions (Alldrick et al., 1986).

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...

The Asmari Formation was deposited in the foreland basin of southwest Iran (Zagros Basin). Carbonate sequences of the Asmari Formation consist mainly of large benthic foraminifera along with other skeletal and non-skeletal components. Three assemblage zones have been recognized by distribution of these large foraminifera in the study area that indicate Oligocene age (Rupelian-Chattian). Absence...
