fluorite finds at the Yunxiao digging site

In our upcoming special "China II" issue, Bert Ottens will sort out and describe the various recent Chinese localities for worldclass stibnite specimens. The Big Three are the Xikuangshan, Lushi and Wuning (or Wuling) mines, but a fourth locality, only slightly less important, is much less well known: it is the Chashan deposit in the Dachang orefield, between the towns of Nandan and Hechi, Guangxi Province. Most commonly denoted "Nandan" or (misleadingly) "Nandan mine" on labels, the Chashan deposit produces superb stibnite specimens which very closely resemble Romanian ones of the "hedgehog" style, with closely packed sprays of bladed stibnite crystals resting lightly on gray-white matrix. At Tucson, outdoors at the Riverpark Inn show, quite an impressive trove of such stibnite specimens could be found with, well, Earth Trove, a dealership from Los Angeles (www.earthtrove .com). In an alcove just inside one wall of the Earth Trove tent, glass cases held about 50 "Nandan" stibnite Tiffany reduced Tiffany Money Clips on sale Key Rings sale Money Clips Links for sale, with flashing metallic gray-black hedgehogs resting singly or intergrown on matrix expanses to 20 cm, the average hedgehog spray being composed of wedge-terminated stibnite crystals to 2 cm long individually.

In our "China I" issue (Jan.-Feb. 2005), Bert Ottens described the now well-known spessartine locality called Tongbei, in coastal Fujian Province. With the abundant specimens of spessartine, smoky quartz, orthoclase and combinations thereof which are dug at the two sublocalities called Yunling and Yunxiao (after villages near the Tiffany Cuff Links sale outcrops), there occur rarely, Ottens writes, pseudo-octahedral crystals of yellow helvite resting on quartz or feldspar. The crystals are dark on their surfaces (like the record-size helvite crystals of Jinlong, reduced Tiffany Rings Key Rings for sale) but yellow inside, and while "helvite crystals discovered (after 2002] lack the dark surface coatings . . . it is suspected that such pieces have been treated in Tongbei with hydrochloric acid." Well, I Tiffany Rings on sale not, since at the show I bought a thumbnail with a sharp, mustard-yellow, 1-cin helvite crystal resting on drusy quartz, from Tongbei. As far as I could learn, Rocko Rosenblatt (rocko@catskill.net) was the only dealer to have brought some of these Tongbei helvite specimens to Tucson, but I note too that a Chinese web dealer named Chen Weigang (www.china-mineral.cn) is also offering them. The pictures on the website show yellow helvite crystals to 1.5 cm, looking just like the one on the thumbnail I purchased from Rocko, resting on matrix of feldspar/quartz/spessartine: the web text says that these specimens were found during the last three months of 2005. The helvite crystals combine positive and negative tetrahedrons; they are very clean and sharp, and they do not look acid-treated, is all I can safely say for now. And by the way. green and purple octahedral crystals of fluorite to 2 cm from Tongbei are also advertised on Chen's website: they represent the first fluorite finds at the Yunxiao digging site, where the species had not yet been found at the time when Bert Ottens composed his article.

More observations on Chinese minerals seen at Tucson might be offered, but I'll save them for the next tiffany Tiffany Necklaces on sale of "what's new in minerals online," and will conclude the tour now with two quick tourist-snaps from the Pacific Rim. Rob Sielecki of Ausrox (rob@crystaluniverse.com.au) brought to his room in the Clarion-all the way from Pernatti's Lagoon near Mt. Gunson, South Australia-about a hundred crystal clusters of gypsum, from 10 to 60 cm across, all collected over a 3-month period in mid-2005. The chisel-shaped gypsum reduced Tiffany Money Clips sale Necklaces reach 3 cm individually, and have grown in solid, mound-like groups, perhaps continuously, even as they were being collected, in the evaporite bed of the lagoon. What else is nifty about these huge specimens is their color: a lovely apple-green, as imparted by run-off into the lagoon from the old, inactive copper mine on Mt. Gunson.
