Copper-mineralised porphyries sample the evolution of a large-volume silicic magma reservoir from rapid assembly to solidification

Publikováno v: Earth and Planetary Science Letters, 563

Volatile-rich intermediate to silicic magmatic systems can feed devastating volcanic eruptions but also generate valuable magmatic-hydrothermal ore deposits that supply most of the world's copper. Understanding the geometry, dynamics and timescales o

Resolving changes in arc magma volatile budgets over Myr timescales leading up to porphyry Cu formation

Autor: Jamie J. Wilkinson, Thomas Knott, Chetan Nathwani, Simon J.E. Large, Yannick Buret

The crustal-scale magmatic systems of Andean-style arcs produce thick volcanic deposits and abundant plutons that are emplaced into the crust. They can also generate spatially- and temporally-restricted, economically-important porphyry Cu deposits. T

Petrological and zircon chemical record of arc magma evolution from long-lived batholith construction to giant porphyry copper deposit formation

Autor: Jamie J. Wilkinson, Chetan Nathwani, Christian Ihlenfeld, Yannick Buret, Adam T. Simmons, Simon J.E. Large

Porphyry Cu ore deposits are a rare product of arc magmatism that often form spatiotemporal clusters in magmatic arcs. The petrogenetic evolution of igneous rocks that cover the temporal window prior to and during porphyry Cu deposit formation may pr

Resolving the timescales of magmatic and hydrothermal processes associated with porphyry deposit formation using zircon U–Pb petrochronology

Autor: Simon J.E. Large, Jörn-Frederik Wotzlaw, Marcel Guillong, Albrecht von Quadt, Christoph A. Heinrich

Publikováno v: Geochronology, 2 (2)
Geochronology, Vol 2, Pp 209-230 (2020)

Understanding the formation of economically important porphyry Cu–Au deposits requires knowledge of the magmatic-to-hydrothermal processes that act within the much larger magmatic system and the timescales on which they occur. We apply high-precisi

Ediacaran glaciations of the west African Craton – Evidence from Morocco

Autor: Dominik Letsch, Marius W. Buechi, Simon J.E. Large, Albrecht von Quadt, Wilfried Winkler

Publikováno v: Precambrian Research, 310

The northern margin of the West African Craton preserved in the Anti-Atlas area of southern Morocco, represents an outstanding geological archive covering parts of the Neoproterozoic and the Paleozoic. Despite isolated mentions in the literature, rel

Northwest Africa’s Ediacaran to early Cambrian fossil record, its oldest metazoans and age constraints for the basal Taroudant Group (Morocco)

Autor: Dominik Letsch, Stefano M. Bernasconi, Thomas M. Blattmann, Albrecht von Quadt, Simon J.E. Large, Wilfried Winkler, Christian Klug

Publikováno v: Precambrian Research, 320

The Anti-Atlas area in southern Morocco preserves one of the most complete latest Ediacaran to Cambrian shallow-marine carbonate records in the world and serves as a standard for global chemostratigraphic δ13Ccarb curves. Contrary to the excellent c

Publikováno v: Journal of Analytical Atomic Spectrometry

Accessory mineral U–Pb geochronology by isotope dilution thermal ionization mass spectrometry (ID-TIMS) requires precise and accurate determinations of parent–daughter isotope ratios. The small sample size, particularly with respect to radiogenic
