B928 - Chamosite psuedo. Almandine $ 260 DISCOUNTED 40% OFF TO $ 156
 Michigamme Mine, Marquette Co., Michigan
small cabinet - 5.5 x 3.5 x 3 cm


Chamosite psuedo. Almandine from Michigamme Mine, Marquette Co., Michigan [db_pics/pics/b928a.jpg] Chamosite psuedo. Almandine from Michigamme Mine, Marquette Co., Michigan [db_pics/pics/b928b.jpg] Chamosite psuedo. Almandine from Michigamme Mine, Marquette Co., Michigan [db_pics/pics/b928c.jpg]

Intergrown pair of crystals of Almandine replaced by Chamosite (the iron analogue of Clinochlore in the Chlorite group of minerals) from the upper peninsula of Michigan. Good sized with crystals to 3.5 cm (most found were less than 3cm). The old label indicates it was in the Frank Hess collection and identified it as 'Aphrosiderite', however Aphrosiderite is an obsolete name and Chamosite is the correct species name. I only have the Hess label, but this specimen is also shown on the Arkenstone website and indicates it was from the historical garnet collection of SMITH COLLEGE, Northampton, Massachusetts and ex. Dr. Gary Hansen Collection.

Mottramite over/after Quartz from Mina Oujela, Mapimi, Durango, Mexico [db_pics/pics/d126a.jpg] Mottramite over/after Quartz from Mina Oujela, Mapimi, Durango, Mexico [db_pics/pics/d126b.jpg] Mottramite over/after Quartz from Mina Oujela, Mapimi, Durango, Mexico [db_pics/pics/d126c.jpg] Mottramite over/after Quartz from Mina Oujela, Mapimi, Durango, Mexico [db_pics/pics/d126d.jpg]

Oujela Mottramite is common enough, but I've never seen a specimen from here of Mottramite over Quartz crystals. There are numerous crystals of Quartz that are either covered by or replaced by Mottramite. There is Quartz at the base of the specimen, but when I look closely at the bottoms of the crystals at the edge, I can see no Quartz in the cores, which leads me to believe the Quartz has been replaced by Mottramite.
