Highly cracked and isomerized archaeal lipids and bacterial lipids, structurally changed by thermal stress, are present in solvent extracts of 2,707- to 2,685-million-year-old (Ma) metasedimentary rocks from Timmins, ON, Canada. These lipids appear in conventional gas chromatograms as unresolved complex mixtures and include cyclic and acyclic biphytanes, C36-C39 derivatives of the biphytanes, a...

 The article describes Reza gold deposit of Ugur exploration area located in Geda- bek Ore District the Lesser Caucasus NW Azerbaijan. It is established that main mineralization consists hematite-barite-quartz-kaoline veins- veinlets and breccia, pyrite stock-stockverk quartz-sulfide veins. On orebody surface center secondary quartzites with vein-veinlets barite-hematite have occured over...
Abstract In recent years, various geological activities and different mineral prospecting exploration programs have been intensified along the Red Sea hills in order to elucidate maps evaluate potentials. This study is therefore aimed at testing viability of using remote sensing geographic information system (GIS) techniques for mapping gold mineralization area. The area located northeast Sudan...
