Text Description:
Sample of olivine basalt from Fox Castle. Fox Castle is a huge pile of loose lava blocks forming a “castle” which seems to represent the top of a dike or neck that has penetrated the tuffs in the Esogemunga fissure. The rock is well crystallized with conspicuously zoned laths of plagioclase, 1-2 mm long. According to their extinction angle the average composition is around An55. Intersertally are olivine, pyroxene, and some ore in grains of 0.1-0.5 mm.
