Text Description: Sample of a vesicular, columnar flow or sill of aphyric olivine basalt. The rock consists of large, randomly oriented laths of plagioclase forming an irregular meshwork filled with olivine, augite, apatite, and magnetite, the latter being in large measure a reaction product of olivine; indeed, the olivine has the properties of pure forsterite, indicating that the fayalite component has been used up in the reaction.
