Comments on the geologic information

  • ; BDLY, ZRCN, (CLD); POCOS DE CALDAS ALKALINE INTRUSIVE IS EMPLACED IN GNEISS AND GRANITE OF THE BRAZILIAN SHIELD. THE UNDERLYING ROCKS OF THE PLATEAU ARE DOMINANTLY PHONOLITE, NEPHELINE SYENITE, AND MINOR AMOUNTS OF VOLCANIC AND SEDIMENTARY ROCKS. THE EMPLACEMENT OF ZIRCONIUM BEARING ALKALIC ROCKS WAS FOLLOWED BY THE LEACHING OF ZIRCONIUM BY HYDROTHERMAL SOLUTIONS PROBABLY ALKALINE ACCOMPANIED BY WALL ROCK ALTERATION AND SUBSEQUENT DEPOSITION OF OXIDE AND SILICATE ARE IN OPEN SPACES. LATER OXIDIZATION AND ENRICHMENT UPGRADED THE ZIRCONIUM CONTENT OF THE DEPOSITS.
