This specimen is from the first find of Blue Wavellite in the State of Arkansas (personal communication with Mike Howard),

This is a specimen of black Arkansas wavellite that I posted previously but this time with better photographs.
The following is a quote from rockhoundingAR copyright 2011 by J. Michael Howard and I use it with his permission:
Some of the Saline County yellow wavellite is very fluorescent, a nice apple-green color, as a very thin coating of the last mineral deposited. A location in Polk County yielded crystal coatings of yellow microcrystals in a milky quartz matrix. White wavellite, due to the absence of vanadium, is known from several locations including: the Montgomery County quarry, where it is often gradationally intergrown with various shades of green wavellite; the Wilson Springs vanadium mine where it formed as small colorless to white crystalline spheres on limonitic matrix; from one of the novaculite quarries at Hot Springs as thin colorless to white radiating films on black novaculite; and at the Christy vanadium mine east of Magnet Cove in Hot Spring County where I recovered a couple of specimens on dark gray novaculite matrix. A recent find of wavellite from the Montgomery County quarry also turned up some blue-green (almost turquoise colored) wavellite. By far the rarest color is black. Until recently, I was under the impression that black wavellite was simply colored by inclusions of dark clay, but I discovered on a bargain table at one of the local rockshops at Hot Springs several pieces that had distinctive black botryoidal crusts and a nice crystalline luster. The color is solid and uniform across a 2 mm layer in one pocket and several other pieces have half a sphere bright green and the other half black. This material also recently came from the Montgomery County quarry.
Mike told me recently that the color in the black wavellite is due to the presence of shale particles.

Today I want to start a post on minerals from Perovskite Hill, Magnet Cove, Arkansas, USA.
The first specimen is an anatase pseudomorph after octahedral perovskite. There are several smaller tan anatase pseudomorphs on the main crystal and it appears that the transition is not complete in some areas.
I found an article on a study of Brazilian anatase pseudomorph after perovskiite for any of the members of FMF who might be interested. Conversion of perovskite to anatase and TiO2 (B): A TEM study and the use of fundamental building blocks for understanding relationships among the TiO2 minerals. Jillian F. Banfield, David R. Veblen, American Mineralogist, Volume 77, pages 545-557, 1992 is the reference.
