Short Course 01

Geology of Natural Diamonds – Reviews in Mineralogy & Geochemistry

Presenters: Graham Pearson (University of Alberta), T. Stachel, F. Nestola, S. Shirey, K. Smit

Duration: Two days

Location: University of Alberta, Edmonton, Alberta

Description: This short course focuses on the mineralogy, geochemistry, and genesis of natural diamonds. Classroom lectures by pre-eminent diamond scientists (e.g., Stachel, Pearson, Shirey, Smit, Nestola, Luth, Navon, Harris, Smith, Breeding, D’Haenens-Johannson, Nimis) will cover the contents of a to-be-published Mineralogical Society of America Reviews in Mineralogy and Geochemistry volume dedicated to the science of natural diamonds. Attendees will receive a copy of the Reviews in Mineralogy and Geochemistry volumes (RiMG) volume in their registration package. Specific topics covered will be: 

  • Diamond occurrences and deposits
  • Monocrystalline diamond: morphology, surface features, and inclusions
  • Polycrystalline and fibrous diamond
  • Non-cratonic diamond: UHP metamorphic, ophiolitic, and impact
  • Crystallographic approaches to diamonds and their inclusions
  • Geochemistry of mineral inclusions in lithospheric diamonds
  • Mineral inclusions in sub-lithospheric diamonds: their compositions and non-destructive Raman identification
  • Fluid inclusions in fibrous diamonds
  • Thermobarometric methods for pressure and temperature determinations from diamond inclusions
  • Geochronology of diamonds
  • Spectroscopy, defect centers color, treatments
  • Synthesis of diamond and identification of synthetics
  • Experimental petrology applied to natural diamond growth
  • Carbon and nitrogen isotope systematics of natural diamond
