Florencite (Ce,La,Nd)[Al.sub.3][([PO.sub.4]).sub.2][(OH).sub.6]
A massive chunk of florencite from the Naipa pegmatite was collected by Mark Bandy and came later into the collection of the Los Angeles County Museum of Natural History.
It was found to contain monazite (later reidentified as brockite) and florencite in subordinate amounts.
(1965) and Trace (1960), reported thorium-bearing and rare-earth-bearing fluorite with sphalerite, galena, barite, monazite (later found to be brockite), florencite, bertrandite, calcite, quartz, pyrite, brookite, yttroparisite (?), biotite, rutile, xenotime and apatite.
