Geology of the Southeast Half of Iron Mask Batholith
نویسنده
چکیده
Major systems of northwesterly, northerly, and northeasterly trending recurrilig fractures or faults controlled emplacement of various units of the Iron Mask batholith. The batholith was emplaced in a high level volcanic to subvolcanic environment, comagmatic with Nicola volcanic rocks and coeval with part of the upper Nicola succession. The batholith intruded volcanic and sedimentary rocks of the lower Nicola but the Cherry Creek unit occurs both as fragments within, and is in intrusive contact with, uppermost Nicola rocks.
