Mineral Specimen #4383 Specular Hematite, Quartz, Dolomite with minor Chalcopyrite
Republic Mine, Republic, Marquette Co., Michigan
12.1 x 7 x 4.3 cm
Ex. A. E. Seaman Museum
Squat, off-white colored Quartz crystals completely cover a core of massive, specular Hematite. At one end of the specimen, the Quartz is sprinkled with sparkly micro crystals of specular Hematite. At the same end, there are a few bladed crystals of peach colored Dolomite. There is also an unidentified, white colored material on some of the crystals. Of note is the presence of some minor Chalcopyrite which was rarely found at the mine (see the next to last photo at the upper right hand corner of the massive Hematite). Such specimens from this location are seldom available. The mine has been shut down since 1982 and even the dumps have been fenced off and no collecting has been allowed for the last 10 years. Currently an asphalt company is hauling away waste rock to crush. See the following for a great description of the mine Republic Michigan in the Upper Peninsula and the Republic Mine .
Flaws: There are a few broken Quartz crystals in a couple of places on the specimen.
