Origin of the Surigao iron ores | Economic Geology ...
Abstract. The iron ore deposit of Surigao, Mindanao, Philippine islands, occurs as a surficial mantle over serpentinized ultrabasic rocks. The ore is lateritic in origin, having been derived by subaerial decomposition of the parent serpentine rock. The Surigao deposit resembles closely the lateritic iron ores of Mayari, Cuba.
