The opening of the Equatorial Atlantic Ocean constitutes the final stage of Gondwana’s breakup, leading to the separation of the African and South American continents. The early spreading has been debated due to the absence of magnetic anomalies related to the Early Cretaceous opening at low latitude, and an incomplete fracture zone record, hidden by … Read more…
Porphyry copper deposits contain the majority of the world’s discovered mineable reserves of copper. While these deposits are known to form in magmatic arcs along subduction zones, the precise contributions of different factors in the subducting and overriding plates to this process are not well constrained, making predictive prospectivity mapping difficult. Empirical machine learning-based approaches … Read more…
Porphyry copper (Cu) systems occur along magmatic belts derived in subduction zones. Our current under- standing of their formation is restricted to observations from the overriding plate, resulting in a knowledge gap in terms of processes occurring in convergence zones through time. An association between key tectonic processes and the timing and location of porphyry … Read more…
