Subject category Comment text
Deposit THE HIGH-GRADE HEMATITE DEPOSITS OF MINAS GERAIS, BRAZIL, ARE THOSE AVERAGING MORE THAN 66% FE AND LESS THAN 1.5% H20. THEY OCCUR IN THE CAUE ITABIRITE, A METAMORPHOSED OXIDE- FACIES IRON FORMATION OF PRECAMBRIAN AGE. THIS FORMATION WAS INTRICATELY FOLDED DURING AN OROGENY THAT METAMORPHOSED PELITIC ROCKS TO THE GREENSCHIST AND ALMANDINE-AMPHIBOLE FACIES, ACCOMPANIED BY THE FORMATION OF GRANITIC ROCKS. THE FOLDING PRODUCED MUCH PLASTIC ROCK FLOWAGE TOWARD THE AXES OF MANY FOLDS, THICKNESS OF THE ITABIRITE RANGING FROM A FEW TO MORE THAN 1,400 M. THE GREAT MAJORITY OF THESE ORE BODIES ARE ASSOCIATED WITH FOLDED STRUCTURES IN THE HOST ITABIRITE, A FEW ARE ASSOCIATED WITH PREORE THRUST FAULTS, AND SOME WITH ABRUPT STEEPENING OF REGIONAL LINEAR STRUCTURE. MOST OF THE ORE OCCURS IN THE LOWER, MORE SILICEOUS TWO THIRDS OF THE ITABIRITE; SOME OCCURS IN THE UPPER THIRD, WHICH IS LOCALLY DOLOMITIC. THE ORE MINERAL IS DOMINANTLY HEMATITE. IT WAS FORMED DURING THE METAMORPHIC CYCLE, AFTER THE FOLDING.
