Mineralogical characterization of asian dust collected in fukuoka, southwest japan
TLDR
Mineralogy of Asian dust collected in Fukuoka, Southwest Japan, was investigated using X-ray diffraction (XRD) and scanning/transmission electron microscopy (SEM/TEM) in detail as mentioned in this paper.Abstract:
Mineralogy of Asian dust collected in Fukuoka, Southwest Japan, was investigated using X-ray diffraction (XRD) and scanning/transmission electron microscopy (SEM/TEM) in detail The dust consisted of only silicates ; quartz, albite, orthoclase, amphibole and phyllosilicates (muscovite/illite, biotite, chlorite, kaolin group minerals and smectite) This mineral composition for silicates is very close to that of a certified reference specimen for Asian dust (CJ-1) which was collected from the loess plateau in China However, carbonate minerals abundant in CJ-1 are missing in Fukuoka dust Probably the carbonate and other water-soluble minerals were dissolved by rain or during sample collection using water Observation and X-ray chemical analysis in SEM revealed their morphologies and chemical compositions Amphibole, biotite and chlorite are major Fe-bearing minerals in the dust Among them, fine chlorite particles may be a good Fe-supplier for microorganism living in the shallow area of the oceanread more

TL;DR: In this article, the authors analyzed samples of dust from the Greenland Ice Sheet Project 2 (GISP2) ice core, Summit, Greenland, dated within marine isotope stage 2 (between 23,340 and 26,180 calendar years B.P.) around the time of the coldest, local, last glacial temperatures, to determine their provenance.

Heterogeneous chemistry of individual mineral dust particles from different dust source regions: the importance of particle mineralogy
TL;DR: In this article, the chemistry of individual dust particles from four different dust source regions is investigated on a particle-by-particle basis using state-of-the-art scanning electron microscopy techniques including computer-controlled Scanning Electron Microscopy/Computer-Controlled energy dispersive X-ray (CCSEM/EDX) analysis.
