Elements Determining in the Geological-Structural Model of the Erdenetuin-Obo Copper-Molybdenum Ore Field, Mongolia
Copper-molybdenum mineralization in Mongolia is localized within the limits of regional structures referred to as the superimposed metallogenic belts. The latter is spatially controlled by the late Paleozoic (in Southern Mongolia) and late Paleozoic-early Mesozoic (in Northern Mongolia) volcanic belts, elongate in a sublatitudinal trend. The through-going transverse fault system of the northwest trend has played an important role in forming ore-concentrating structures. Intersection of transverse faults and ones that trend along the volcanic belt account for the development of a block fabric and highly permeable zones that are favourable for the existence of long-lived magmatic centers that host the ore fields.
