Black tabular crystals to 0.5mm in aggregates (second photo) 5mm across. The reverse side has stringers of Cechite. The crystals are tabular with pyramidal forms and look very similar to Descloizite, which is not too surpising given the formula and crystal classes of each. In fact Cechite is a member of the Adelite-Descloizite group. The matrix is Calcite. Very nice peice.

This is an interesting specimen of dickthomssenite, a magnesium vanadate, with an assortment of habits including needle-like crystals, platy crystals, radiating prismatic crystals, and bubbly efflorescent masses. The color is mostly a creeamy white.
Dickthomssenite is named in honor of Dick Thomssenite. Dick is a geologist based in Tucson, Arizona. He has been involved in many new finds of minerals throughout west, including Arizona, Nevada, and Utah. As a geologist he has worked in the Upper Peninsula of Michigan, Alaska, Nevada, California and South Dakota. He was inducted into Micromounters Hall of Fame in 1985. His micromounts are top-of-the-line and expertly mounted. He was associate editor of the Mineralogical Record. He also co-authored the Nevada Mineral Locality Index with Steve Pullman.
Dick and Peter B. Leavens undertook a Smithsonian & National Geographic Society sponsored expedition in the summer of 1967 to geologically explore and collect fine specimens of Epidote on Copper Mountain and Green Monster Mountain, Prince of Wales Island, Alaska. The locality became a classic locality for world class Epidote. Their exploration culminated in an article in the Mineralogical Record (1977). Peter Bancroft wrote a chapter on this epidote in his book "Gem and Crystal Treasures", a must have book for any mineral collector. A photo of Dick can be seen on page 115. He is smiling because they dug a single 10cm, 1 kg crystal.
