davidite :... Found in pegmatites associated with quartz, biotite, ilmenite, rutile, iron and copper sulfides. Also found in hypersthene gabbro and anorthosite accompanied by scapolite, quartz, calcite, molybdenite, rutile, sphene, and tourmaline; it is obvious that the mineralization was introduced into the basic rocks by emanations from underlying granites. This is the only known occurrence of primary uranium minerals in basic rocks. One of three known primary uranium ore minerals.  2, record 1, English, - davidite
