 note = {岩石の成因の中で火成岩は，時間的変遷をもつことから他の成因より多様性形成では重要性をもつ。固体からマグマの形成までの過程で化学的多様性を生む要因を考察した。マグマ形成の過程では，起源物質と溶融の素過程が重要である。起源物質では，化学的分化が，時間効果で大きな変化となり，端成分マントルとなった。端成分マントルは，対流に伴う機械的混合によって多様性を広げていった。溶融過程では，固体物質が，温度上昇，圧力低下や成分添加などによって，マグマが形成される条件が達成される。溶融は，平衡か分別か，共融系か固溶体系か，溶融程度などの要因が加わってマグマに化学的多様性が生じる。マグマ形成には，単純な規則性で多様性を生み出すメカニズムが組み込まれている。, The igneous rocks change chemically with time. They have the importance in formation of chemical variations compared with the other origin of a rocks. In this paper, the factors in their chemical diversity were considered from the solid (mantle or source materials) to formation of a magma. The elementary processes in the magma generation are divided into source materials and melting. In the processes of source materials, a little chemical differentiation generates mantle end-members with time effect. The mantle end-members were expanding chemical diversity by mechanical mixing with mantle convection. In the processes of melting process, the condition of a magma generation depending on rising temperature, falling pressure or adding components is achieved in solid material. The chemistries of magma diverse by factors; equilibrium melting or differentiation melting, eutectic system or solid solution system, a degree of melting. The mechanism which produces chemical diversity by the simple regularity is included in magma formation., Bulletin, 論文, Article},
