NEW MINERAL

POSTITE, BLACK HAT MINE, LA SAL DISTRICT, SAN JUAN COUNTY, UTAH



These are specimens from the new mineral, POSTITE.  Postite's chemical formula is Mg(H2O)6Al2(OH)2(H2O)8(V10O28)13H2O and was recently named.  There are 3 photos on www.mindat.org  http://www.mindat.org/gallery.php?min=42268 .  The crystals are micro with the mindat photos having a field of view of 1 mm and taken with a microscope.  I believe that collecting has been limited at best.  I was able to acquire 30 specimens from a local collector last year before the work on the description for the new mineral was complete.     December 2011 

UPDATED INFORMATION:
These Postite specimens are from the Black Hat Mine.  Mindat lists the Postite locations as Paradox Valley District which is incorrect.  It is the La Sal District. The type location is the Vanadium Queen Mine and a second location is the Blue Cap Mine.  Photos and this third location will probably be added to mindat in the future. These were collected at the Black Hat Mine about two years ago prior to being described which was finished and approved as a new mineral only recently.  The Black Hat Mine has since been sealed by the state of Utah.  Specimens collected from the Black Hat Mine had EDS Analysis which confirmed that Mg Al and V present.  I believe Postite presently is the only Vanadium species with Aluminum present.
