Deposit ACTINO;ITE SKARN AND PYROXENE HORNFELS DEVELOPED AT CONTACT BETWEEN ALKALINE GRANITIC PHASE OF A GRANODIORITE PLUTON AND LIMESTONE. ORE: 60-80% SPECULAR HEMATITE, 20-40% MAGNETITE. OREBODY 5 M THICK AND 150 M LONG. ALSO: HEMATITE IN QUARTZ-BARITE VEINLETS.
Deposit CARACAHUI IS AN IRON SKARN DEPOSIT FORMED BY THE INTRUSION OF A UPPER K (LARAMIDE) GRANODIORITE INTO LOWER K REPRESSO FORMATION LIMESTONES. THE LIMESTONES ARE ASSOCIATED WITH CONTEMPORANEOUS VOLCANISM. THE IRON SKARN IN THE REGION TYPICALLY HAVE HIGH FE PERCENTAGES, (41.2-66.8%). THE CARACAHUI DEPOSITS CONTAIN ONLY 60% SI AND LOW S (1.385%). LESS THAN 5% OXIDIZED MAGNESIUM AND .020% MN. ; INFO.SRC : 1 PUB
