Abstract Seven major and numerous lesser Fe oxide occurrences within the 1.47 Ga St. Francois Mountains terrane in Missouri (USA) have previously been described as iron oxide-apatite (IOA) oxide-copper-gold (IOCG) deposits. Researchers speculate that these contain significant amounts of critical minerals, most notably rare earth elements cobalt. One less-studied deposits region is 1.455 Kratz Spring deposit. The deposit consists two steeply dipping magnetite bodies beneath 450 m sedimentary...

The Southeast Missouri Iron Metallogenic Province in the Midcontinent USA contains seven major and several minor IOA/IOCG-type deposits a series of shallow vein-type deposits/prospects, all which are spatially temporally associated with early Mesoproterozoic (1500–1440 Ma) magmatism St. Francois Mountains terrane. One is Shepherd Mountain deposit, consists two northeast-trending ore veins dominated by magnetite lesser amounts hematite. Here we report findings study that investigates origin...

Abstract The amount of ultimately recoverable resources and/or timing peak production have been the central purpose numerous studies. One broadly applied method is Hubbert modeling, subsequently extended as multicyclic modeling. This paper explores a modification to conventional modeling that we term “cycle‐jumping” wherein overlap multiple curves limited and explicitly accounted for. model designed in way each curve described by same three parameters model, every two are connected through...
