Abstract This paper discusses results obtained from in situ analysis of the tesserae Roman mosaic Los Amores (Cástulo site, Linares, Spain) dating back to turn 1st 2nd century AD. Specifically, it focuses on scene The Judgment Paris. In view exceptional state preservation mosaic, which very few had fallen off, non-invasive methods with portable Micro Raman Spectroscopy (MRS) and hand-held X-ray...

Ferromanganese nodule nuclei are considered crucial to the formation and distribution of nodules. However, because it is difficult time-consuming study ferromanganese nuclei, few studies have been performed, despite large number samples. Here, we analyzed 934 nodules from abyssal seafloor around Minamitorishima Island (western North Pacific Ocean) using X-ray computed tomography (CT). Based on ...

A novel two-step sequential extraction has been developed to assess the bioaccessibility of As, Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn in airborne particulate matter following inhalation and transport into the human gastrointestinal tract by mucociliary clearance. A new artificial mucus fluid (AMF) was used to determine the bioaccessible potentially toxic element (PTE) fraction in the upper airways,...

A gravel pit in south central Stearns County, Minnesota exposes sand and gravel of the Merden Lake esker which is thought to have been deposited by a subglacial stream associated with the Wisconsinan-aged Superior Lobe of the Laurentide ice sheet. An analysis of these sediments was conducted from samples collected through a vertical trench on an east-facing exposure of the gravel pit. A total o...

Old, climate-buffered infertile landscapes (Ocbils) have attracted increasing levels of interest in recent years because of their exceptionally diverse plant communities. Brazil's campos rupestres (rupestrian grasslands) are home to almost 15% of Brazil's native flora in less than 0.8% of Brazil's territory: an ideal study system for exploring variation in floristic diversity and phylogenetic s...

This study reviews the available data on Phanerozoic plume activity (Large Igneous Provinces (LIP’s) size and frequency) geochemistry of their igneous rocks. A major goal this review is to try find changes in intensity mantle plumes linked Earth’s evolution galactic seasonality that was supposed authors’ previous publications. The indicate Cambrian–Ordovician Jurassic–Cretaceous summers were as...
