We review and refine the geological setting of an area located nearby Tyrrhenian seacoast, in inner zone Northern Apennines (southern Tuscany), where a Neogene monzogranite body (estimated about 3 km long, 1.5 wide, 0.7 thick) emplaced during early Pliocene. This magmatic intrusion, known as Gavorrano pluton, is partially exposed ridge bounded by regional faults delimiting broad structural depr...
An assemblage of hydrous, Cl-bearing alteration-induced minerals is present within 150 m of footwall-style Cu–Ni–PGE sulfide mineralization hosted by the Sudbury Breccia at the Fraser Copper zone, Fraser mine, Onaping–Levack area, Ontario. The pyroxene hornfels to hornblende hornfels contact-metamorphic aureole of the Sudbury Igneous Complex (SIC) contains less than 15 modal % hydroxysilicates....
Abstract The Arbus igneous complex (SW Sardinia, Italy) represents a good example of short time lived post-collisional composite pluton emplaced at shallow crustal level in the external zone Variscan chain. almost consists granodiorite and leucogranite rock- suites 304 ± 1 Ma within main NW trending thrust separating metamorphic wedge from fold belt foreland. into dilatational step over connect...
The limitations of many in situ microsampling techniques, especially when applied to isotopic analyses, may result lower measurement precision and limit the ability compare different isotope systems within same phase or system between phases. High-precision, combined complementary measurements are typically limited whole-rock samples mineral separates at expense textural context. We demonstrate...
