Geochemistry and origin of elements of Upper Triassic Olang coal deposits in northeastern Iran
The Olang area is a part of Gheshlagh-Olang synclinal, which is a member of eastern Alborz coal basin and is situated at a distance of70 km northeast of Shahroud city. Coal-bearing strata of this region are part of the Shemshak group (Upper Triassic to Lower Jurassic).Samples from the 9 coal seams of the Olang coal deposits were collected and ashed. The aim of this study is to determine theoccu...
متن کاملMercury isotopic evidence for multiple mercury sources in coal from the Illinois basin.
Coal combustion is the largest source of anthropogenic mercury (Hg) emissions to the atmosphere and, thus, has vast environmental implications. Recent developments in Hg stable isotope geochemistry offer a new tool for tracing sources and chemical transformations of anthropogenic Hg in the environment. We present here the first isotopic study of mercury in organic and inorganic constituents of ...
متن کاملبررسی ویژگیهای ژئوشیمیایی و کانیشناسی زغال سنگهای حوزه زغالی کارمزد، البرز مرکزی، استان مازندران
The Karmozd coal mine in Mazandaran Province (Iran) is one of the largest and oldest active coal mines in Central Alborze Coal Basin. A complete geochemistry and mineralogy characterization of Karnozd coal has been conducted in summer, 2005 by sampling of coal, coal tailing and country rock coal Basin.The coal layers (Lias) is embedded in the middle of Karmozd litostratigraphic unit. It is comp...
متن کاملBiological marker geochemistry of selected oils and possible source rocks from central Alborz Basin
Surface oil seeps from Alasht, Lapur and Jenesem share many compositional affinities including distributions and concentrations ofnormal alkanes, terpanes and steranes. These oils also show many similarities with that of Jurassic sediments (Shemshak Group, KlarizFormation) systematically sampled from the Galandrud Coal Mine. Recent geochemical studies in this area indicated that theShemshak Gro...
متن کاملThe Dublin SURGE Project: geochemical baseline for heavy metals in topsoils and spatial correlation with historical industry in Dublin, Ireland
The Dublin SURGE (Soil Urban Geochemistry) Project is Dublin's first baseline survey of heavy metals and persistent organic pollutants in topsoils and is part of a Europe-wide initiative to map urban geochemical baselines in ten cities. 1,058 samples were collected as part of a stratified random sampling programme in the greater Dublin area to give an overview of baseline conditions in the city...
