Thermographic non-destructive evaluation for natural fiber-reinforced composite laminates [PDF]
, 2018 Natural fibers, including mineral and plant fibers, are increasingly used for polymer composite materials due to their low environmental impact. In this paper, thermographic non-destructive inspection techniques were used to evaluate and characterize ...

Clinopyroxene Dissolution Records Rapid Magma Ascent
Frontiers in Earth Science, 2020 Magma ascent rates control volcanic eruption styles. However, the rates at which basaltic magmas ascend through the crust remain highly uncertain. Although recent studies have successfully exploited records of decompression driven degassing to estimate ...

Archaeometric Analyses of Medieval Pottery From the Lower Danube Region, Romania
ChemPlusChem, Accepted Article.This paper discusses the pottery manufacturing in the Lower Danube region during the Early Medieval period. Optical Microscopy (OM), Particle Induced X‐ray Emission (PIXE) and X‐ray Diffraction (XRD) were performed on thirty‐two ceramic shards unearthed at Pantelimonu de Sus, Romania, dated to the 8th‐10th c. AD. The petrographic observations showed an

How Much Water in Basaltic Melts Parental to Porphyry Copper Deposits?
Frontiers in Earth Science, 2020 Porphyry copper deposits are formed by aqueous fluids exsolved by differentiated, mantle-derived magmas variably mixed with crustal melts. Water is essential to form porphyry Cu mineralization, and this explains why these deposits are found only at ...

The Depositional Record, EarlyView.Halite thickness in Mbr 2 of the Kumugeliemu can reach 1000 m. The thick halite is associated with sedimentary rock with shallow water fabrics. The thick halite was formed in a shallow‐sea water environment. The ‘Multiple transgression‐salt‐forming’ model was established.
