Rosell Minerales
RM2181 Baryte "rose"
Lake Thunderbird area, Norman, Cleveland Co., Oklahoma, United States of AmericaExcellent, sculptural, two-sided baryte "rose" from Oklahoma. Oxidized sand grains are included in the baryte crystal structure with colorful effect. Essentially a floater. The hole adds much aesthetics. Baryte was precipitated in interconnected voids in the rock, probably from barium-rich marine waters that covered the Permian Garber Sandstone during or shortly after its deposition about 250 million years ago. The rose-like concretions incorporated the iron-stained quartz sand grains and thus acquired the red color of the host Garber Sandstone (online). These are the official Oklahoma State Rock.
Very interesting article in Mineralogical Record July-August 2008.
Size: 6.2 x 4.6 x 4.2 cm.
