In low temperature aqueous solutions, it has long been recognized by in situ experiments that many minerals are preceded crystalline nanometre-sized particles and non-crystalline nanophases. For magmatic systems, precursors have not yet demonstrated to exist, although the suggestion around for some time. Here we demonstrate high quench platinum arsenic self-organize nanoparticles, well before melt reached a Pt-As concentration at which discrete Pt arsenide become stable phases. If all highly...
Skeletal remains in archaeological strata are often assumed to be of similar ages. Here we show that combined Sr and O isotope analyses can serve as a powerful tool for assessing fish provenance even identifying fossil teeth contexts. For this purpose, established reference dataset extant from major water bodies the Southern Levant. Fossil shark were identified within Iron Age cultural layers dating 8–9th century BCE City David, Jerusalem, although reason their presence unclear. Their...
The Um Rus tonalite-granodiorite intrusion (∼6 km2) occurs at the eastern end of Neoproterozoic, ENE-trending Wadi Mubarak shear belt in Central Eastern Desert Egypt. Gold-bearing quartz veins hosted by were mined intermittently, and initially ancient Egyptians until early 1900s. relationship between gold mineralization, host intrusion, regional structures has always been unclear. We present new geochemical geochronological data that help to define tectonic environment age intrusion. In...
