Geological structure and localization of mineralization
 at the Moryanikho-Merkurikhinskoye ore field

Abstract

The paper discusses the lithological and facial features
 of the terrigenous-carbonate (biohermic) ore-bearing
 geological formation of the Moryanikho-Merkurikhinskoye
 ore field (Yenisei Ridge), which hosts stratiform
 lead-zinc deposits in carbonate strata. Ore-hosting lithofacies
 and their paleostructural position are characterized.
 Based on the previous studies, as well as the author’s
 own materials obtained as a result of field work, the
 main favorable lithological, facial and structural factors
 for hosting Moryanikhinsky-type stratiform lead-zinc
 mineralization are defined: the presence of paleodepressions
 within the shelf zone; development of carbonate
 rocks – dolomites, stromatolite dolomites and limestones,
 which are biohermic structures on the slopes of
 paleo-uplifts; the presence of an admixture of tuffaceous
 material in terrigenous rock varieties.
 The influence of tectonic faults on the formation of
 ore deposits and the morphology of ore bodies is indicated.
 The main types of ores of the Moryanikho-
 Merkurikhinsky ore field, as well as their mineral composition
 are described. The paper discusses the main ore
 types, as well as their mineral composition typical of the
 Moryanikho-Merkurikhinskoye ore field. The largest and
 well-studied lead and zinc stratiform Moryanikhinskoye
 deposit and Merkurikhinskoye ore occurrence located
 within the ore field are briefly characterized.
 The Moryanikhinskoye deposit is a typical example
 for searching for stratiform deposits of lead and zinc in
 the carbonate strata of the Angara-Bolshepitskaya mineragenic
 zone, which is of practical interest in developing
 predictive prospecting models of deposits and improving
 the efficiency of prospecting.
