Presentation Transcript

  1. Ch.1 Introduction • Geochemistry? • Geo (geology, gaia) + chemistry • A field of study dealing geological phenomena and problems with chemical tools and principles • Prerequisites? • Physical geology, minerlaogy, petrology, economic geology • General chemistry, inorganic chemistry, physical chemistry

  2. Early history • 1838, Chritian Friedrich Schönbein (Basel Univ., Switcherland) first used the term ‘Geochemistry’. • 1908-1924, Frank W. Clarke (USGS, USA) published the monumental book “The Data of Geochemistry”. • 1924, Vladimir IvanovichVernadskypublsihed “Geochemistry” (Russian). 1926, publsihed “The Biosphere” (Russian). • 1934-1939 Alexander Fersmanpublsihed 4 volemes of “Geochemistry” • 1888-1947 Victor M. Goldsckimdt primarily studied elemental distribution and crystal chemistry.

  4. More history • 1952 B. Mason’s “Geochemistry”-first widely used textbook of geochemistry. • R.M. Garrels, W. Stumm, & J.J. Morgan.  Aqueous geochemistry • K.B. Krauskopf, H. Helgeson, R.A. Robie, J.M. Hollaway, D.K. Nordstrom, R.G. Berman  Geochemical thermodynamics • P. Currie & M. Curie, E. Rutherford, F. Soddy, B. Boltwood, A. Holmes (1913, The Age of the Earth)  Geochronology • H. Urey, H. Craig, G. Faure  Stable isotope geochemistry • B.P. Tissot & D.H. Welte.  Organic geochemistry

  5. Study fields of modern geochemistry • Crystal chemistry • Isotope geochemistry • Igneous/metamorphic (petro)geochemsitry • Aqueous geochemistry • Organic geochemistry • Biogeochemistry & geomicrobiology • Geochemical analysis • Geochemical exploration • Cosmogeochemistry • Environmental geochemistry

  6. What would be the future of geochemistry? • Discussion • Recognized international journals • Geochimica et CosmochimicaActa (GCA) • Chemical Geology • Applied Geochemistry • Organic geochemistry • Biogeochemistry • Geochemistry International • Environmental Geochemistry & Health • Journal of Geochemical Exploration
