Our April featured speaker was Dr. Jeff Walker to discuss and demonstrate a portable X-ray fluorescence spectrometer useful for identification of elements present in even trace amounts in minerals.
Thanks to our March speaker Professional Geologist Eric Orlowski. He provided us with very interesting slides and information on the theory, science and some of the commercial uses of zeolites that include chemical processing, water softening, and laundry detergent. Mark Kucera has again provided an interesting synopsis in his meeting minutes.
