Text Description:
Dike trending NW-SE that cuts through andesite flows located in between Sites 8 and 9. Fine-grained, vesicular, diktytaxitic, holocrystalline, seriate to glomeroporphyritic with a matrix of cryptocrystalline material, plagioclase, opaque, clinopyroxene and red alteration. Plagioclase phenocrysts (An34 - An57) are up to 0.5 mm and some larger grains are zoned. Orthopyroxene phenocrysts are up to 0.3 mm. Clinopyroxene phenocrysts are up to 0.3 mm.
