The Seagull Creek batholith and its metamorphic aureole Gower, John Arthur
Abstract
The main features of the Seagull creek batholith are described. The most noteworthy of these is the abundance of boron in the granites themselves and in the contact aureole. This has led to the formation of miarolitic cavities containing tourmaline, to the formation of tourmaline and axinite veins and disseminations in the surrounding rocks, and to the formation of magnesium iron borates in a contact metamorphic iron deposit. Laboratory studies and reference to literature on similar rocks have led to the following conclusions: 1. Boron was a major constituent of the final residual liquid of the Seagull creek magma. 2. Segregations, either gaseous or liquid, from this final liquid caused the formation of miarolitic cavities in the granite. 3. Fine grained and aplitic phases of the Seagull creek granite are younger than the coarser grained phase. 4. The rocks are similar in many respects to those of Cornwall, Seward peninsula, Alaska, and other tin bearing regions.
