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...

Abstract Granitoids with diverse composition and tectonic settings provide important tools for exploring crustal evolution regional geodynamic history. Here we present an integrated study using petrological, mineralogical, zircon U-Pb geochronological, whole-rock geochemical, isotopic data on the Late Triassic Daocheng batholith in Yidun Terrane a view to understanding petrogenesis of compositi...

This work deals with the petrographic and geotechnical characterization of rocks from N'goura massif focus on their use in civil engineering. The study area is located central southern Chad, about 205km to north N'Djamena. monzogranitic two micas. outcrop as blocks, slabs balls displaying fine, medium coarse grained minerals. Monzogranite composed 34% quartz, 32% alkali feldspar...

• Gold mineralization occurred in the subduction stage of Early Paleozoic Proto-Tethys ocean, and its age is limited between 454 Ma 439 Ma. H-O-S-Pb-Hf isotopes indicate a magmatic-hydrothermal source, closely related to monzogranites. The Heihaibei gold deposit may instead be classified as granitic intrusion-related deposit. newly discovered southern part Eastern Kunlun Orogenic Belt. Its most...

Primary tin deposits usually contain little or no copper due to the distinct geochemistry of Sn and Cu. However, examples copper-rich in many provinces around world are also well known. The genesis remains controversial. Maodeng Sn-Cu polymetallic, a typical Cu-rich deposit southern Great Xing’an Range (SGXR) Northeast China, offers an excellent opportunity reveal coupled copper-tin deposits. o...
