Monazite - WikipediaMonazite is a reddish-brown phosphate mineral that contains rare-earth elements. Due to variability in composition, monazite is considered a group of minerals.[3] The most common species of the group is monazite-(Ce), that is, the cerium-dominant member of the group.[4] It occurs usually in small isolated crystals. It has a hardness of 5.0 to ...Specialty Items - USGSHistorical and Time Series Data Data Series 140 - Historical Statistics for Mineral and Material Commodities in the United States - A compilation of data on mineral production, imports, exports, stocks, reported and apparent consumption, and unit value (the value in dollars of a metric ton of apparent consumption) for approximately 90 mineral commodities from as far back as 1900.Rare Earths Statistics and Information - USGSMining Engineering, v. 68, no. 10, p. 36-43 Historical Statistics for Mineral and Material Commodities in the United States Data Series 140 Rare Earths Metal Prices in the United States through 2010 Scientific Investigations Report Potential forUSGS: Mineral Resources On-Line Spatial Data: leadMining districts, mines, and mineral occurrences (deposits and prospects) within the United States that are reported to contain enrichments of rhenium (Re) Info Rock Geochemistry and Mineralogy from Fault Zones and Polymetallic Fault Veins of the Central Front Range, Colorado
