  1. A description of #Haüyne fluorescence at: gemologyproject.com/wiki/index

    These samples are found in a quarry near the Laacher See (Eifel Mts, Rhineland-Palatinate, Germany)

    This crater was formed only ~13,000 years ago in an eruption similar in size to the 1991 Pinitubo eruption -in central Europe!

  6. #Sanidine from the Fish Canyon Tuff is essential to understanding the pace of events in the #Cenozoic

    High potassium, quickly erupted and cooled, and old enough to have accumulated sufficient 40Ar from radioactive decay. These crystals calibrate neutron flux for 40Ar/39Ar dating. The 28.2 Ma age of the FCT sanidine has been fine-tuned using #Milankovitch cycles of other ash beds in stable sedimentary basins.
