In their paper, Spiess et al. (2021) published structural, geochronological, and EBSD data on one of the monzogranite apophyses (Capo Bianco) buried Porto Azzurro Pluton (island Elba, Northern Apennines, Italy), a pluton emplaced in upper crust (P < 0.2 GPa; e.g. Papeschi al., 2019). The authors new U/Pb age 6.4 ± 0.4 Ma, associated with thermal peak, U-Th/He apatite 5.0 0.6 indicating cooling ...

The method of bi-dimensional empirical mode decomposition (BEMD) and the combined methods entropy weight–Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) were used decompose gravity–magnetic data evaluate targets in Luziyuan Pb–Zn–Fe polymetallic ore field surrounding areas. Three meaningful intrinsic function (BIMF) images obtained BEMD at different wavelengths, depic...

The metamorphosed mafic-ultramafic sequences of the Eastern Andean Metamorphic Complex outcropping in Patagonian Andes are critical to disclose late Paleozoic tectonic evolution southwestern margin Gondwana. In study area, bodies thrusted onto polydeformed metasedimentary rocks and intruded by mid-Carboniferous composite Leones Pluton. metabasalts (mostly tremolite-chlorite schists amphibolites...
