Abstract
One of the most important features of the Newania carbonatite is that it hosts Cu and pyrochlore mineralization. Chemical data of pyrochlore indicates that it is remarkably rich in U (up to 22.92% UO2). It is concluded that the crystallization of highly uraniferous pyrochlore essentially started in very early stage (cumulate phase) of crystallization of carbonatite (rauhaugite) magma at Newania which had elevated concentration of both Nb and U.
