Harris Wash, a tributary of the Escalante River in south-central Utah, has two wellpreserved alluvial terraces of compound origin in its lower reaches. The alluvial stratigraphy of the deposits that compose these terraces reflects the complex processes of canyon filling and erosion. The compound terraces were formed by general aggradation of the valley, by deposition from large floods that also...

Principal Skarn deposits along the northern margin of the Ahar batholith from west to east include Mazraeh, Vine and Gowdoul skarn deposits. Among these skarn deposits, the Mazraeh Cu-Fe Skarn deposit is the most typical skarn deposit in the NW Iran. This skarn deposit is located 5 km. north of Mazraeh village and 20 km north of Ahar town. The origin and development of the skarn can be related ...

At the ultrastructural level two main categories of microvascular anomalies can be distinguished in the aged rat brain. These categories comprise [1] membranous inclusions within the basement membrane and [2] microvascular deposits, which include microvascular fibrosis and thickening of the basement membrane (BMT). In this study we examined the percentage of microvessels displaying ageing-relat...

OBJECTIVE To study the clinical and pathologic features of systemic lupus erythematosus (SLE) that has atypical lupus nephritis (LN) with mainly IgA deposits. METHODS We searched the SLE patients who had nephritis with mainly IgA deposits in our hospital and selected the information including clinical manifestations, laboratory tests, treatments, and prognosis. RESULTS From January 2009 to ...

Carbonatite-associated rare-earth-element (REE) deposits are the most significant source of the world's REEs; however, their genesis remains unclear. Here, we present new Sr-Nd-Pb and C-O isotopic data for Cenozoic carbonatite-hosted giant REE deposits in southwest China. These REE deposits are located along the western margin of the Yangtze Craton that experienced Proterozoic lithospheric accr...

Two morphological types of prion protein (PrPsc) deposit occur in the cerebral cortex of cases of variant Creutzfeldt-Jakob disease (vCJD), viz., diffuse and florid deposits. The objective of this study was to determine whether diffuse-type PrPsc deposits in areas of the cerebral cortex in six cases of the variant form of CJD (vCJD) were spatially correlated with neurons and whether diffuse dep...

This study investigated the contamination of abraded Ti surfaces. Using a polishing machine, specimens were abraded with waterproof SiC grit papers under water cooling. The abraded surfaces were examined using element analysis, X-ray diffraction, and hardness tests. Contaminant deposits with dimensions reaching about 30 microns were observed throughout the surface. In these deposits, Ti was app...

Electrodeposition of Si on substrates such as Ni, Ag and GC from acetonitrile and tetrahydrofuran containing SiCl4 and SiHCl3 as precursors is reported. The deposits readily oxidize on exposure to air but XPS analysis of a deposit withminimum contact with air confirms that elemental Si (2p, 99.5 eV) is electrodeposited. The deposits contained C, O, N and Cl impurities; annealing under argon imp...

The phenomena of white deposits on glass which is in direct contact with or a short distance from an historic, mainly textile, object has been described in literature since the 1970s. The introduction of this article is a short summary of the history of the linen bands of the Liber Linteus. A literature overview throws light on research done in the field of deposits on glass, concerning the obs...

Most rare earth element deposits form from magmatic fluids, but there have also been discoveries of heavy rare earth element (HREE)– enriched hydrothermal xenotime deposits within sedimentary basins. As xenotime is notoriously insoluble, the question arises as to whether these lesser-known deposits form at typical basin temperatures or by influx of much hotter magmatic-hydrothermal fluids. The ...
