Deposits of clastic carbonate-dominated (calciclastic) sedimentary slope systems in the rock record have been identified mostly as linearly-consistent carbonate apron deposits, even though most ancient clastic carbonate slope deposits fit the submarine fan systems better. Calciclastic submarine fans are consequently rarely described and are poorly understood. Subsequently, very little is known especially in mud-dominated calciclastic submarine fan systems. Presented in this study are a sedimentological core and petrographic characterisation of samples from eleven boreholes from the Lower Carboniferous of Bowland Basin (Northwest England) that reveals a >250 m thick calciturbidite complex deposited in a calciclastic submarine fan setting. Seven facies are recognised from core and thin section characterisation and are grouped into three carbonate turbidite sequences. They include: 1) Calciturbidites, comprising mostly of highto low-density, wavy-laminated bioclast-rich facies; 2) low-density densite mudstones which are characterised by planar laminated and unlaminated muddominated facies; and 3) Calcidebrites which are muddy or hyper-concentrated debrisflow deposits occurring as poorly-sorted, chaotic, mud-supported floatstones.

Principles Of Fluorescence Spectroscopy

Green Chemistry is a relatively new emerging field that strives to work at the molecular level to achieve sustainability. The field has received widespread interest in the past decade due to its ability to harness chemical innovation to meet environmental and economic goals simultaneously. Green Chemistry has a framework of a cohesive set of Twelve Principles, which have been systematically surveyed in this critical review. This article covers the concepts of design and the scientific philosophy of Green Chemistry with a set of illustrative examples. Future trends in Green Chemistry are discussed with the challenge of using the Principles as a cohesive design system (93 references).

Interparticle Coupling Effect on the Surface Plasmon Resonance of Gold Nanoparticles: From Theory to Applications

Biological denitrification in a novel ion exchange membrane reactor (IEMB) has been investigated. The polluted water was separated from the mixed denitrifying culture by a non-porous mono-anion permselective membrane providing continuous exchange of nitrate for chloride added as a counter-ion to the biocompartment. A removal efficiency of 87% and a surface removal rate of about 1400 mgNO 3 - /m 2 .h was achieved at a nitrate concentration of 150 mgNO 3 - /L. The treated water stream was essentially free of ethanol, used as a carbon source, and NO 2 - ions whereas the original water conductivity was completely preserved due to very efficient Donnan exclusion of the cations present in the two solutions from the membrane used. The IEMB process showed higher removal efficiency and better nitrate selectivity compared to a Donnan dialysis process operated under similar conditions.
