On the hornblende-andesite of Nabesima-daké, southern Kyûsyû, and the xenolithic blocks in it

Abstract

The megascopical and microscopical characters of the xenolithic blocks in the Nabesima lava constructing a tholoide in the southern Kyusyu, Japan, seem to be a representative of the bulbs of liquid magma intruded into different one. Such phenomenon may happen under a certain favourable condition when a magma intrudes into an immiscible one belonging to anot ?? reservoir, although it is hardly proved at present.
