|One of many field trips offered to the public to aid and educate prospectors and geologists on where |
to find gemstones, diamonds & gold. On this trip, Hausel discusses pyrope garnet and chromian diopside found in anthills at Butcherknife Draw in southwestern Wyoming. Hausel, a Hall-of-Fame geologist with the Wyoming Geological Survey at the University of Wyoming
(1977 to 2007); and a Hall-of-Fame martial arts instructor with the Departments of Physical Education, Kinesiology, Club Sports and Extended Studies (1977-2010) at the University of Wyoming; a geological consultant for mining companies (1988-present) and author of more than 1,000 publications, is the most awarded geologist and martial arts instructor in the history of the University of Wyoming and Wyoming Geological Survey. Dozens of awards were presented to Hausel by international, national and local associations- these included the Education Award from the Rockhound Hall-of-Fame, the Thayer Lindsey Award from the PDAC in Canada, and the Wyoming Geological Association Distinguished Service Award.

Although olivine was known in Wyoming since the late 19th century, no one had bothered to examine the clarity of the calcium-magnesium-silicate until Hausel followed up on reports of olivine in the Leucite Hills in 1997. To his amazement, much of the olivine was gem-quality and during reconnaissance of the lamproite field in southwestern Wyoming in a search for diamonds, he recovered more than 13,000 carats of gem-quality peridot in two anthills near Black Rock. The anthills were collected and taken back to the Wyoming Geological Survey to be processed and verify the discovery. The quality of the majority of the stones was very high and the anthills contained gems from 1 mm to 12 mm long, while larger gemstones were found in nearby soils between the anthills and the Black Rock lamproite by sieving the soils. Later (2005), the GemHunter conducted field investigations in the Leucite Hills volcanic field to map the lamproites and search for potential diamonds, since the peridot was derived from mantle xenoliths and xenocrysts eroded from the lamproites. Worldwide, peridot is a tracer mineral used to search for diamondiferous lamproite, similar to the classical diamond indicator minerals associated with kimberlite. Lamproite is only one of two host rocks mined for commercial amounts of diamonds in the world. To verify the quality of the Wyoming peridot gemstones, many were cut in Sri Lanka and sent back to the Geological Survey in Laramie where the faceted stones were displayed in the foyer at the Dr. Daniel N. Miller building on the UW campus.
