Monitis Creek

The Monitis Creek is a phosphorus-phosphates mine located in Alaska.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Exploration): Status = Inactive

Comment (Geology): Geologic Description = The phosphate occurrences are confined to the black chert and shale member of the Alapah Limestone. Interbedded phosphorite and phosphate rock occur in sections up to 11.3 m thick. The phosphate-bearing mineral consists of fluorapatite, which is concentrated in oolites, pellets, and matrix. Purple fluorite occurs locally. The phosphatic rocks can be traced for 1.5 km along strike.

Comment (Reference): Primary Reference = Kurtak and others, 1995, USBM OFR 8-95

Comment (Workings): Workings / Exploration = Individual phosphorites up to 0.6 m thick contain up to 330% P2O5. One 6.7 m-thick section averaged 23% P2O5. Samples also contained up to 2,000 ppm V, and 119 ppm U.

Comment (Deposit): Model Name = Bedded phosphorite

Comment (Geology): Age = Mississippian
