Novel polyfunctionalised geohopanoids in a recent lacustrine sediment ( Priest Pot , UK )
نویسنده
چکیده
The sediment of a highly productive lake (Priest Pot, UK) contains the biosynthesised hopanoid bacteriohopanetetrol (BHT) and a series of hopanediols and triols. These polyols represent intermediate stages in the conversion of biologically produced hopanoids to the diagenetic products, hopanes. Two of these geohopanoids, assigned as trishomohopane-32,33-diol and bishomohopane-30,31,32-triol have not been previously reported in recent sediments, and their identi®cation, in addition to that of tetrakishomohopane-32,33,34-triol and a bishomohopanediol gives valuable information on the original composition and subsequent diagenesis of bacteriohopanepolyols within recent sediments. # 2000 Elsevier Science Ltd.

A novel sedimentary transformation product of chlorophyll, purpurin-7 phytyl ester, has been identi®ed by atmospheric pressure chemical ionisation liquid chromatography mass-spectrometry in sediments from Lake Baikal, Russia, Loch Ness and Priest Pot, UK. This product of oxidative transformation is an intermediate on the transformation pathway leading to sedimentary aetioporphyrins and its occu...

Results of laboratory tests on specimens produced from subsoil studies were evaluated tocharacterize geotechnical properties of Tabriz Marl. It was concluded that, Tabriz Marl may be considered as a high liquid limit silt or clay (MH & CH). Range of changes of index, physical and mechanical properties of the Tabriz Marl are comparatively vast. Correlation between these properties has been intro...

This paper presents results from the numerical modelling of the transport of atmospheric noble gases (He, Ne, Ar, Kr, Xe), tritiated water and He produced by radioactive decay of H, in unconsolidated lacustrine sediment. Two case studies are discussed: (1) the evolution of H and He concentrations in the sediment porewater of Lake Zug (Switzerland) from 1953 up to the present; and (2) the respon...

A long history of research focused on the East Africa cichlid radiations (EAR) revealed discrepancies between mtDNA and nuclear phylogenies, suggesting that interspecific hybridisation may have been significant during the radiation of these fishes. The approximately 250 cichlid species of Lake Tanganyika have their roots in a monophyletic African cichlid assemblage, but controversies remain abo...
