Arizona Mineral Collector Number 153 By Dr. Raymond Grant
The Kingman Feldspar mine is located a few miles north of I40 on the east side of Kingman. I was there quite a few years ago, and at that time it was very easy to drive to and could be seen from a distance. I bring it up this month, as it is location of a number of new minerals to add to the list of Arizona mineral species. There are two references, one in Rocks and Minerals, volume 82, page 236-237, May/June 2007, it is an abstract “Rare-Earth Mineralogy of the Mohave County Pegmatites, Northwestern Arizona”, and the other is in the Canadian Mineralogist, volume 50, page 815-824, August 2012 and is titled Allanite-(Nd) from the Kingman feldspar mine, Mohave pegmatite district, northwestern Arizona, USA.
The nomenclature for minerals such as allanite that can have different elements predominate is to add a suffix showing the major element. Each of these minerals is considered a distinct species. In the Mineralogy of Arizona we just listed the mineral as allanite, but based on the new research we have two minerals allanite-(Ce) with cerium and allanite-(Nd) with neodymium. Allanite-(Nd) is a relatively new mineral, and this is the first verified occurrence in the United States. When I was at the mine there was a lot of allanite exposed in the walls. I had a crystal (rough shape) over a foot long. It was quite radioactive, and I’m not sure where I stashed it. I think it is in the
The above references list thorogummite (new for Arizona) as inclusions in the allanite. This is part of the source of the radioactivity. They also report aeschynite-(Y) and bastnasite-(Ce), both of which are new for the Arizona list, giving us four new minerals for Arizona. Monazite and xenotime were also found and these were determined to be monazite-(Ce) and xenotime-(Y). Previously they were just listed in the Mineralogy as monazite and xenotime.
Colorado River Basin Water Supply & Demand Study
The Colorado River Basin Water Supply & Demand Study just released by the Bureau of Reclamation will be a topic of discussion at the conference. Carly Jerla, Program Manager on the study will give a talk on the current and future imbalances in water supply and demand in the Colorado River Basin over the next 50 years, and the adaptation and mitigation strategies to resolve those imbalances.
