持続可能な社会を維持するためには、天然資源を効率的に利用する必要がある。近年､天然資源のうちとくに鉱物資源（金属資源）の消費が急増し、それに伴い資源探査の難易度も高くなっている。資源探査には資源が形成される過程の地質学的・地球化学的モデルを理解することが不可欠である。本講義では代表的な鉱物資源について資源地質学的観点から資源の産状を学ぶとともに、成因モデルについて理解を深める。
The efficient exploitation of natural resources is essential to retain the sustainable development of our society. A rapid increase in demand of natural resources, especially metallic mineral resources, arises recently, and this causes the increase in difficulty for mineral exploration. The understanding of genetic geological and geochemical models of mineral deposits are very important for mineral exploration. In this lecture, occurrences and genetic models for several types of mineral deposits will be given.
地球を含む惑星の形成と進化について、特に量子ビームを活用した実験岩石鉱物学の研究成果について議論する。
In this course, students who study different fields of the Earth and planetary materials introduce their recent experimental results. This course offers an opportunity to think about the origin, evolution and structure of the Earth and planets.
地球では、地殻-海洋-大気の3構造圏が相互に作用することにより物質循環が進行し、ここに生物圏が関わることで地球の環境が作られる。さらに時間スケールを広げればこの循環はマントルや核を含む全地球の循環として機能している。従って、環境の成り立ちあるいは地球の変動を解明する目的において、物質の循環を理解しなくてはならない。地球上の同位体分布は物質の起源と流れをほぼ直接的に反映しており、その理解により時間的・空間的な環境構造の見極めが可能となる。現環境における同位体分布を決定している化学的および生化学的原理を理解し、地球型環境形成との関わりにおいて地質学を同位体化学的に究明する基礎を学習する。年代の決定は地球化学的プロセスを解明する上で不可避の作業であり、本授業では特に年代決定論について、具体例を挙げ解説を行う。
Understand the chemical and biochemical principles that determine the isotopic distribution in the existing environment and learn the basics that an isotope studies geology in relation to global environment formation.
