安定同位体を用いた鉱床、マグマ、岩石成因論
Geochemistry of Ore Deposits
酸素、水素、炭素、硫黄の安定同位体を用いて、天水、地熱水、マグマ水の起源を議論する。さらに玄武岩や花崗岩の起源、糖小マグマの起源を議論する。炭酸岩の進化、無酸素海洋の進化、海底熱水鉱床、正マグマ性鉱床、スカルン鉱床、斑岩銅鉱床の成因も議論する。ダイアモンドやキンバライトの成因も議論する。
This is a lecture to understand various ore deposits including petroleum and diamond.
安定同位体の応用に関する理解
Understandings on stable isotopes
This lecture will cover the following topics: (1) application of stable isotope geochemistry to understand natural phenomena, (2) origin of magma, (3) origin of metallic ores, (4) origin of oil, and (5) evolution of biosphere through the earth history.
（１）Introduction
What are stable isotopes? Concept of isotope fractionation.
Technical terms for stable isotope geochemistry.
Isotope equilibrium
（２） Meteoric water: isotope fractionation during rain precipitation.
(oxygen/hydrogen isotopes)
Rayleigh isotope fractionation
（３）Terrestrial hydrothermal system: origin of hot springs
(Oxygen isotopes of magma/mantle)
（４） Sulfur and carbon isotope system (general)
（５） Origin of magmatic ores
（６） Origin of submarine hydrothermal ore deposits 1
（７）Origin of submarine hydrothermal ore deposits 2
（８）Biological fractionation of stable isotopes: carbon
（９）Biological fractionation of stable isotopes: sulfur
（１０）Origin of oil and natural gas
（１１）Origin of diamond
（１２）Origin of meteorite
