マグマ発散物の分化現象と火山発散物

概要

The magmatic emanations separated from the mother magmas or igneous bodies differentiate into solid, liquid and gaseous phases on account of coolng, depression of pressure, and reactions depending on the physical, chemical and geological environments. On the ground surface at the atmospheric temperature and pressure, these three phases formed are called the volcanic sublimates (solid), the volcanic waters (volcanic hot springs) (liquid) and the volcanic gases (gas), respectively. Variation in the nature and properties of these volcanic products at each stage of differentiation is explaind by the cooling of the magmatic emanation and the model experiments. Genetical relations among many volcanic emanations can be explained by the standpoint of physical chemistry of the magmatic emanations. For further details, see "Differentiation of magmatic emanation." (Iwasaki et al. 1966).
