... mineralization is related to Tertiary-age emplacement of monzonite intrusive rocks and intermediate volcanic rocks ( Garcia & Querol 1991). The mineralization consists of massive sulphide skarn in the El Carrizal and El Monte mines hosted in the A/T Formations to the N and W of the town ( Fig. 2). The ores...

... Rosario Mine ( Fig. 2 ), was given the name El Plan Formation by Carpenter (1954 ). The beds were described as probably flood-plain or shallow-marine deposits. They have long been regarded as the oldest unmetamorphosed sedimentary unit exposed in Honduras, of Late Triassic to Jurassic age. The name...

Five meters of gypsum are exposed, interbedded with redbeds, about 1 km northwest of Encarnacion ( Fig. 1 ), and several meters of gypsum crop out in the south bank of Río San José about 2.5 km northwest of Encarnación. Conglomerate beds below the gypsum...
