| The primary topic of
Bulletin 108 is ophiolite-related gold quartz veins in the North
American Cordillera. It discusses the setting of lode and placer
gold occurrences in proximity to ophiolitic rocks not only in British
Columbia but also throughout the North American Cordillera. A new
mineralization model is presented that concisely defines the
characteristics of some gold occurrences associated with
mafic-ultramafic rocks in orogenic belts. Details and
interpretations of the geology in the Atlin area, within the Cache Creek
Terrane, as well as in the Bralorne-Pioneer, Rossland, Barkerville and
Cassiar areas of BC are presented, including comparative discussions of
the Alaska-Juneau deposit, and California gold deposits such as Grass
Valley and Motherlode.
There is an extensive description of
ophiolite geology, the tectonic setting and descriptive geology for
ophiolite-related deposits. The regional treatment and the
detailed deposit geology presented in each chapter is a concise
evaluation of the setting, process and deposit features for this
distinctive Cordilleran gold deposit type.
This publication also details exploration
criteria applicable to finding new occurrences or expanding potential
for known deposits. The information presented is applicable to
gold exploration in orogenic belts internationally. |
