An excellent specimen with hundreds of tiny white bladed Rongibbsite crystals to maybe 0.75mm in vugs. 

Rongibbsite is named after Ron Gibbs an eminent mineralogist of the southwestern US. Ron brought many rare phosphates and arsenates to market and personal collections. He is coauthor of the book "Mineralogy of Arizona" 4th edition. He also authored the book "Agates and Jaspers" in 2009. His profession as a mining engineer landed a job at the famous New Cornelia mine in Arizona and later in Tyrone and Silver City, New Mexico. You will always see Ron at the New Mexico Mineral Symposium and of course the Tucson show.

Ron along with Joan Beyer wrote a paper on Granite Gap, Hidalgo Co., NM. Their collecting culminated in many new occurences of minerals from this locality. The offiicial citation is: Beyer, J., Gibbs, R. (2002) Minerals of the Granite Gap Mines, Hidalgo County, New Mexico. Rocks & Minerals: 77(5): 298-305.

There are several Rongibbsite specimens in this Special Edition. This one is the by far the best with an abundance of crystals in several vugs. Rongibbsite is a very rare zeolitic aluminosilicate with extra framework lead. It is monoclinic forming white to colorless bladed crystals as radial sprays or randon single crystals.

Tiny lemon yellow platy crystals with Khinite(?). Thorneite is named in honor of Brent Thorne.

Brent by trade is a chemist. He is a prolific mineral collector and is responsible for bringing dozens of new minerals and new occurences to the light day including Tombstoneite, Flaggite, and Tomiolloite. He is one of the best mineralogist that I know. He is a fine photographer and many of his photos can be seen on Mindat and the Mineralienatlas. 

The original description of Thorneite was pubilshed in the American Mineralogist: click here.

Olive green micro-crystal groups of Timroseite at the red arrow plus other groups near the center of the specimen. The two other groups are on the order of 0.75mm in size and then there are at least a dozen smaller, irregular, hemispherical masses composed of platy crystals to about 0.3mm. The Timroseite is associated with bluish Mohaveite, bright green Khinite, light bluish green Chrysocolla, and Formacite. Excellent choice, rich specimen straight out of Tim's collection.

I first met Tim Rose (not to be confused with Tim Rose of the Smithsonian) at the NCMA symposium probably in the late 1990's. Tim is a seasoned and expert geochemist and mineralogist. He was one of the many collectors who first collected at the Otto Mountain, which has yielded (so far) 16 type locality minerals. Click here for the puplished paper on Timroseite.
