Mineral Specimens with Ferrimolybdite
- 4 specimens selected
A superb, unusually rich specimen of CRYSTALLIZED Ferrimolybdite from a classic locality , probably from the early 1900s. Usually one sees only a crust of microcrystals with no distinct form, but here we have true crystals. Rich on both sides of the specimen. ex. American Museum of Natural History, with label
5.1 x 3.3 x 1.6 cm. A superb, unusually rich specimen of CRYSTALLIZED Ferrimolybdite from a classic locality, probably from the early 1900s. Usually one sees only a crust of microcrystals with no distinct form, but here we have true crystals. Rich on both sides of the specimen. Ex. American Museum of Natural History, with label.
11.0 x 6.7 x 4.1 cm. Molybdite is an uncommon molybdenum oxide and this cabinet specimen is a rare and rich specimen from New Mexico out of the Mullane Collection. Pastel-yellow molybdite richly covers the metallic-gray molybdenite and quartz on both sides of this old-time piece from the Questa Molybdenum Mine in Taos County. Accompanied by an old and faded handwritten label.
6.2 x 3.3 x 2.2 cm. The now defunct Urad mine was a small scale Molybdenum mine on the east slope of the Continental Divide in Colorado (just up the hill from the Henderson mine). Very few specimens from this mine were ever recovered and made available on the market. This specimen is a good example of the well known hydrated iron molybdate, Ferrimolybdite, featuring powder yellow patches of crude crystals on matrix. Ferrimolybdite typically forms as an alteration of Molybdenite in these hydrothermal veins along the Colorado Mineral Belt. The specimen was collected in the mid 1970's, and is one of the few I have seen from the Urad mine. It is also one of the few specimens from the Urad mine from the well known Richard A. Kosnar Colorado collection.
