Uranium Rock Variety! Jurassic Canyon 2.5 and 50 similar items

NATURAL URANIUM ROCK ASSORTMENT 2.5 LBS (40 OZ) VARIETY OF ROCKS FROM JURASSIC CANYON, 18 MILES NW FROM GRANTS NM This rock collection is sold by WEIGHT, not by number of rocks. It will be 8-20 rocks, depending on the rocks' weight and size. Jurassic Canyon is the richest uranium field in the entire USA, and it is the fourth richest uranium field in the entire world. The "mother lode" of uranium here is 3,000 ft deep, 600 ft thick, and it extends horizontally at depth for six miles, passing directly beneath the Mount Taylor extinct volcano and the Jurassic Canyon uranium field. FIVE VARIETIES OF URANIUM make up this rock collection, although these varieties are not equally represented; one or more might be missing in the 2.5 lb (40 oz) assortment. The varieties found at Jurassic Canyon NM are: / COFFINITE / CARNOTITE / / TYUYAMUNITE / URANINITE / or / JURASSIC TODILTO LIMESTONE. / When you buy a 40 ounce collection, I will enclose a two-sided descriptive sheet for each rock type, reprinted from Wikipedia. By studying these five two-sided sheets, you will be able to identify the type-identity of each rock in your own 40-ounce uniquely varied uranium rock collection. These rocks were mined at a 3,000. ft depth, where they existed for 150-200 million years, in the shadow of the Mount Taylor uranium shield volcano. Many dinosaur species occupied this region during the Jurassic era of the ancient world. The rocks are arranged in two groupings, based on their cpm (counts-per-minute) radiation level. The groupings are: LOW-LEVEL (3,000. cpm to 7,000 cpm) and also MID-LEVEL (8,000 cpm to 30,000 cpm). Each rock's cpm radiation level is stated clearly on the gummed sticker attached to the metal foil surrounding the rock. The radiation level for the rock is highly accurate. A Ludlum Model 2200 geiger-scaler is used to identify the rock's radiation; this geiger-scaler is the most accurate geiger instrument available to "rockhound" hobbiests like me. Rocks that are ABOVE 30,000. CPM radiation level will continue to be sold individually in the ads; they will NOT be part of the variety groupings. STORING YOUR ROCK VARIETY COLLECTION I recommend that each uranium rock should have its metal foil removed, and should be stored in a clear plastic "zip-lock" bag, to which a gummed label has been attached, stating the rock's cpm value. Then place the bags of each rock category, LOW-LEVEL or MID-LEVEL, into one of the two large metallic bags. This way, you will always know where the two groups of rocks are being stored. LAST TWO PHOTOS: Mount Taylor Mine, near the canyon, has mined more uranium than any other USA mine. NOTE THE RATTLESNAKE GUARDS on my lower legs. Jurassic Canyon's main wildlife: the ever-present Diamondback Rattlesnakes ! SHIPPING must be only to buyers with a USA address, because selling uranium rocks is only allowed to USA buyers, according to a regulation of the Federal Nuclear Regulatory Commission.
