Mineralogy, geochemistry and genesis of Temelieh Manganese ore Deposit (NorthWest Selseleh, Lorestan Province)

This contribution illustrates the procedures of calculating rare earth element (REE) patterns of magmatic fluids in equilibrium with granitic melts. These patterns can then be compared to those of altered and (or) mineralized rocks in order to investigate the source of the ore-fluids. This technique is applied to the Lake George Sb-Au-W-Mo mineral deposit, New Brunswick, Canada. The results sug...

The determination of the Ultimate Pit Limit (UPL) is the first step in the open pit mine planning process. In this stage that parts of the mineral deposit that are economic to mine are determined. There are several mathematical, heuristic and meta-heuristic algorithms to determine UPL. The optimization criterion in these algorithms is maximization of the total profit whilst satisfying...

the base (cu–pb–zn) and precious metals (ag±au) mineralization at the no. 4 anomaly of golojeh deposit occurred in volcanic and sub–volcanic eocene–oligocene host rocks, in the central part of the tarom–hashtjin zone. basic to intermediate volcanic, volcaniclastic and sub–volcanic rocks are dominated in the area and include andesite, basaltic andesite, trachy-andesite, dacite and tuff with affi...

The Cerro Quema Au-Cu deposit is hosted by a dacite dome complex of the Río Formation, Late Campanian-Maastrichtian volcano-sedimentary sequence Panamanian magmatic arc. Its formational age constrained at ~49 Ma field evidences, crosscutting relationships and 40Ar/39Ar geochronology (Corral et al., 2016, Corral, 2021). recent molybdenite Re-Os dates Perelló al. (2020) claim that ore spatially t...
