NEW TITLE
"Mineralogy of Uranium and Thorium", by
Robert J. Lauf

For students of mineralogy and geology, this book offers a systematic overview of uranium and thorium minerals, many of which are known for their intense ultraviolet fluorescence and are critically important as our source of nuclear energy. Learn about the geochemical conditions that produce significant ore deposits and view more than 600 maps, structure diagrams, color photos, and electron micrographs. A web link allows readers to view the more than 130 crystal structures in three dimensions for a richer appreciation of their details. The minerals are arranged to emphasize how they fit into chemical groups, and a thorough description is provided for each mineral. Major occurrences of interest to mineral collectors are arranged geographically, with maps showing the important deposits in uranium-producing countries. With the resurgence of interest in nuclear power, this book will be invaluable to mineral collectors and exploration geologists as well as to nuclear scientists and engineers interested in radioactive deposits.

SAMARSKITE-(Y) 
Burroughs Mine (Burroughs Pegmatite), Kerr Gulch, South Platte District, Jefferson County, Colorado
The Burroughs Mine has produced very good, rich specimens of Samarskite-(Y) as well as several other rare earth-bearing minerals.  The South Platte District contains over 50 pegmatites, many of them known since the early 1920’s when they were first prospected for Feldspar.  See the accompanying photo of this locality, supplied by Rudy Bolona, a Colorado mineral collector – nice looking place to go field collecting!  The three specimens available from the Burroughs Mine consist of solid black massive Samarskite-(Y), without rock matrix or associated minerals. On a fresh surface, the Samarskite-(Y) exhibits the characteristic, very shiny glass-like luster and conchoidal fracture.  Several flat faces on the back of item C. suggest that this specimen may have formed in contact with crystallized Quartz or Feldspar.

CUPROSKLODOWSKITE
Musonoi Mine, near Kolwezi, Shaba Province, Zaire (Dem. Republic of the Congo)

The Musonoi Mine is famous for its world-class specimens of Cuprosklodowskite, a uranium and copper-bearing silicate.  Classic examples are composed of bright apple-green Cuprosklodowskite most often found as acicular needles, compact radial intergrowths, and fairly infrequently as intergrown aggregates of terminated crystals where voids occur within the matrix.   With the ongoing embargo against importing radioactive minerals from outside of the USA, it has been very difficult for us to find specimens to offer on the web site.  The specimens illustrated here are from a dealer’s stock imported from Zaire more than 25 years ago.  The Cuprosklodowskite on these specimens is present as bright apple green compact-acicular to compact-massive, as shown in the

photos.  Items 2457 and 2687 have massive apple green Cuprosklodowskite.   These are very good reference specimens.

The associated minerals are abbreviated and described below.  A list of the associated minerals found on each specimen is incorporated into the table, below.  Selenium-rich Digenite, also known as selenian Digenite, was first identified from the Musonoi Mine and has yet to be reported from any other uranium mineral bearing deposits, worldwide.  Most of the associates listed are best appreciated with 10-20X magnification.

NOTE:  The three small specimens in lot number 1951 are very good for small reference specimens of Cuprosklodowskite, and can also be used for micromount preparation.  No terminated crystals are present.

Ma = Malachite                   Medium to dark green, acicular to massive veinlets.
Me = Metatorbernite          Medium green, platy.
R = Rutherfordine            Straw yellow to yellow-tan, massive to bladed.
Sk = Sklodowskite             Bright yellow.  Acicular to fibrous, to massive.
V = Vandenbrandeite        Dark green.  Massive, micro crystalline.
SeD = Selenian Digenite  Metallic gray-black, as a minor constituent of the matrix.
K = Kasolite                     Bright yellow micro crystalline.
Ur = Uranophane               Yellow, acicular to massive.
W = Wulfenite                   Massive to non-terminated xl. blades, pale yellow to yellow-brown.
H = Heterogenite             Massive, black.
Sc = Schoepite                   Crystalline to massive, bright butter yellow.
So = Soddyite                    Crystalline to massive, bright canary yellow.

For background information on Cuprosklodowskite, see the special Katanga issue of the “Mineralogical Record” magazine, Vol. 20, No. 4, July-Aug 1989, pages 265-288.  The Nov-Dec 2002 issue (Vol. 33, No. 6) of the “MR”, pages 484-485 has the most current information available about the status of the Musonoi Mine --- along with a photo of the now abandoned mine.  Two photos of exceptional Metatorbernite and Cuprosklodowskite specimens, which were previously collected at Musonoi, also accompany the article.

NEW TITLE

“KATANGA! … URANIUM DEPOSITS”, By G. Gautier, A. Francois, M. Deliens, and P. Piet, 11” X 8”, 63 pages, with 19 color photographs, 12 crystal drawings, several maps and tables, soft cover.  The primary article of interest in this special issue of the “Mineralogical Record” magazine is entitled “Famous Mineral Localities: the Uranium Deposits of the Shaba (Katanga) Region, Zaire”.   Since the days of Stanley and Livingstone, the Shaba region has been known as one of the world’s great mineralized areas.  A crescent shaped deposit about 300 km in length and nearly 50 km wide extends from the town of Kolwezi in the west, to the city of Lubumbashi in the east.  This area is the location of several very important Uranium mines, including familiar names like Shinkolobwe, Swambo, Kamoto, Mashamba-West, Luiswishi, and Musonoi.  The mining history is given in some detail, including notes on the production of Copper and Uranium ores in the Katanga region.  The general geology of the district is given, including a stratigraphical map of the Katanga System.  Four of the most important mines are then discussed in detail, accompanied by geological maps and black & white photos of the mine sites.  Data is then given on each of the important minerals – primary minerals, then secondary Uranium minerals.  This section is accompanied by 19 exquisite color photographs illustrating many of the secondary Uranium-bearing minerals, along with a dozen crystal drawings.  The color photos and crystal drawings will be of prime importance to anyone studying and / or collecting secondary Uranium-bearing minerals, as an aid in visual identification of the minerals from the various mines of the region.  Four tables accompany the text, each containing a list of the minerals found at one of the following mines: Shinkolobwe, Swambo, Musonoi, and Kamoto.  The authors have included a large list of references, for further reading.  Two other articles are included in this special issue of the “Mineralogical Record” magazine – “Rome Delisle and His Bibliography”, by W. Wilson, and “Additions and Corrections to the Glossary of Mineral Species", 5th Edition (1987)” by M. Fleischer.  Published by the Mineralogical Record, Inc., Tucson, Arizona, as the special issue on Katanga, Volume 20, No. 4, July-August 1989.
