| Deposit | THE PICHITA CALUGA DEPOSITS BASICALLY APPEAR TO BE REPLACEMENTS OF LIMESTONE BRECCIA BY GALENA AND SPHALERITE, ALTHOUGH ONE INTERPRETATION SUGGESTS THAT MOST OF THE ORE AT THE BASE OF THE PUCARA GROUP OCCURS IN A BRECCIA AT THE BASE OF THE MITU GROUP AND ONLY MINOR AMOUNTS OF ORE HAVE REPLACED CARBONIFEROUS OR TRIASSIC-JURASSIC LIMESTONE. THE ORIGIN OF THESE BRECCIAS IS OBSCURE; THEY PROBABLY WERE ORIGINALLY SEDIMENTARY BRECCIAS, PERHAPS DEPOSITED IN TROUGHS IN THE UNDERLYING GRAY DOLOMITE, AND ARE STRATIGRAPHIC UNITS RATHER THAN FAULT BRECCIAS. THE BRECCIA ORE CONSISTS OF ANGULAR FRAGMENTS OF LIMESTONE AND OTHER ROCKS. |
