The Bay St. George sub-basin of SW Newfoundland, part the larger late Paleozoic Maritimes basin, formed under influence strike-slip faulting and movement evaporites. New stratigraphic correlations between Newfoundland other sub-basins illustrate effects both basement salt movement. Coastal outcrops show complex combinations synsedimentary, salt-related, tectonic structures. Map relationships dr...

The sedimentary record reveals first-order changes in the locus of carbonate precipitation through time, documented in the decreasing abundance of carbonate precipitation on the seafloor. This pattern is most clearly recorded by the occurrence of seafloor carbonate crystal fans (bladed aragonite pseudomorphs neomorphosed to calcite or dolomite), which have a distinct temporal distribution, ubiq...

The paper presents the results of detailed structural analysis Dzhankhot thrust zone which is a part system overthrust nappe structures in southern slope Northwestern Caucasus. relevance research topic found on reason that despite obvious importance these nappes structure Greater Caucasus there still lack in-situ observational data zones and tectonic stress distribution pattern therein. As resu...

in many applications the quality of a process or product is best characterized and summarized by a functional relationship between a response variable and one or more explanatory variables. profile monitoring is used to understand and to check the stability of this relationship over time. therefore checking the capability of a profile seems essential. process capability indices have become very...

methyl tertiary butyl ether (mtbe) is known as a promising substitute for tetra ethyl lead (tel) in order to increase the octane number of gasoline. mtbe process, as many other processes, has two distinguished section, namely reaction section and separation section. in this paper we focus only on synthesis and optimization of separation section of this process. in order to achieve this objectiv...

the aim of this study was to determine the feasibility of coupling an electrochemical process with a biological treatment in order to degrade phosmet, an organophosphorous pesticide. the absence of biodegradability of phosmet by pseudomonas fluorescens and activated sludge was verified in our operational conditions. so, a conventional biological treatment is not appropriate for phosmet polluted...

Carbonate-hosted Mn deposits are widespread in North Africa with most of the ores being hosted by Mesozoic dolomitic formations Moroccan Atlasic system. The Bou Arfa Mn(-Fe) deposit described herein is located eastern High Atlas, close to Front, and has accounted for production ~2 Mt ore grading from 33 82% Mn. mineralization occurs within Sinemurian flat-lying dolostones as stratabound karst-f...
