"WebDolerite is composed plagioclase, clinopyroxene and opaque minerals. The marginal part of the sill shows hyalo-ophitic textures, inside part show dolerite texture, and the most upper part shows fine-grained dolerite texture. Vesicles are irregular shape, about 1 mm2size, filled with chlorite and quartz. We measured vesicularities of 22 samples. " - Hyalo ophitic texture
