Important Update News

The RRUFF Project has been migrated to RRUFF.net. Please update your bookmarks immediately, if you have not done so.

The data on this website is already three years out of date, and the entire website will be taken offline before the end of the year.

We are grateful to NASA for the funding of this effort.

The Mineral Evolution database is currently under development.

The goal of this page is to present localities at which the mineral is found, and estimates of the oldest possible geologic age of the minerals at these localities.

(1994)	10.1016/0016-7037(94)90043-4	GCA58_3155	The combination of textural evidence and isotopic data from this study indicates that intermittent REE mineralization of the Bayan Obo deposit started at about 555 Ma, and the principal mineralization related to Caledonian subduction occurred between 474 and 400 Ma.; The most important results of this study indicate that (1) the large database of precise chronology, in conjunction with mineral replacement relation, provides evidence for a prolonged period of mineralization within the giant Bayan Obo orebody and (2) lead and neodymium isotopic compositions indicate that the source for the ores was depleted in uranium but enriched in thorium and LREEs.; note spelling as Bastnaesite in lit.
