Chlorite-coats on quartz surfaces are ubiquitous in various sedimentary environments. shield the surface of from cement overgrowths, thus preserving anomalously high porosity deeply buried sandstone reservoirs. The inhibition implies that chlorite-coats grains can significantly influence physicochemical behavior grains. Therefore, failure to notice initial thin microscale coatings forming durin...

Abstract Cu-Ni-Co-PGE mineralization occurs at Haidbachgraben in the Early Palaeozoic, Subpenninic Hollersbach Complex of Central Tauern Window, Austria. Massive sulfide ore formed from melt segregated silicate during intrusion pyroxenite into magmatic rocks an MORB-type environment. Relics minerals include chromian spinel and polyphase droplets composed pyrrhotite, chalcopyrite pentlandite pre...

The Taunsa uranium mineralisation is hosted by the upper Miocene–Pliocene Litra Formation, part of molasse sediments (Siwalik Group) deposited in Himalayan foreland basin eastern Sulaiman Range, Dera Ghazi Khan, Pakistan. Formation only rock unit hosting economic-grade occurrences stratigraphic record Surface radioactivity mainly associated with cemented layers host sandstone, known as hard-ban...

The chemical, morphological and mineralogical properties of two Enon sandy loam (fine, mixed, thermic Ultic Hapludalfs) soilsaprolite profiles, one formed on gabbro and the other on metagabbro, are compared. Clay skins are scarce and stress cutans common in the argillic horizons of these soils. Iron-manganese concretions are concentrated in soil horizons immediately above the argillic horizons....

Chlorination by-products (CBPs) in drinking water have been associated with an increased risk of adverse pregnancy outcomes, including small for gestational age at term (term-SGA) and preterm delivery. Epidemiological evidence is weakened by a generally inaccurate exposure assessment, often at an ecological level. A case control study with incident cases was performed in nine Italian towns betw...

The Mars Exploration Rover Spirit investigated the igneous and alteration mineralogy and chemistry of Home Plate and its surrounding deposits. Here, we focus on using thermochemical modeling to understand the secondary alteration mineralogy at the Home Plate outcrop and surrounding Columbia Hills region in Gusev crater. At high temperatures (300 °C), magnetite occurs at very high W/R ratios, bu...

This study compared the efficacy of chlorine (20-200 ppm), acidic electrolyzed water (50 ppm chlorine, pH 2.6), acidified sodium chlorite (20-200 ppm chlorite ion concentration, Sanova), and aqueous chlorine dioxide (20-200 ppm chlorite ion concentration, TriNova) washes in reducing populations of Escherichia coli O157:H7 on artificially inoculated lettuce. Fresh-cut leaves of Romaine or Iceber...

This Public Health Goal (PHG) technical support document provides information on health effects from contaminants in drinking water. PHGs are developed for chemical contaminants based on the best available toxicological data in the scientific literature. These documents and the analyses contained in them provide estimates of the levels of contaminants in drinking water that would pose no signif...

Elevated As occurs in many meta-sedimentary bedrock aquifers where elevated bulk-rock As content is one of the primary controls on the concentration of As in groundwater. This study was designed to determine As concentrations in a black shale, black slate and black phyllite sequence that comprises the bedrock aquifer system of the Taconic Mountain region of southwestern Vermont and adjacent New...
