Abstract Rift-basins are the shallow effects of lithosphere-scale extensional processes often producing polyphase faulting. Their sedimentary evolution depends on mutual interplay between tectonics, climate, and eustasy. Estimating role each factor is generally a challenging issue. This paper focused tectono-sedimentary Neogene Siena-Radicofani Basin, structural depression located in inner Nort...

Objectives : This study evaluated the effect of dosing yellow clay powder as a sedimentation aid when <i>Microcystis</i> sp. bloomed.Methods Pre-oxidation (chlorination and ozonation) treatment coagulation/precipitation experiments - laden source water were performed with jar-tester. Treatment efficiency was by analyzing turbidity particulate matter supernatant after according to pr...

The principal suppliers of terrigenous material to forming ancient diamond placers are characterized based on the main diamond-bearing districts Siberian platform as an example. A special attention is paid characteristics local sources allothigenous washed out into sedimentation basins period specified, which were weathering crusts formed upon terrigenouscarbonate rocks, trappean formations (do...

The fill of trench-slope basins is complex, varying temporally, laterally, and longitudinally. New data from the Neogene stratigraphy Akitio Sub-basin, Wairarapa, are presented to investigate such variation. preserved basin spans an area 70 km long by 10 wide, representing deposits a basin. Integration sedimentological, micropalaeoentological, geological mapping charts evolution. Over 15 strata...

The lunar Late Heavy Bombardment (LHB) defines a time between ∼3.8 to possibly 4.1 Gy ago when the Nectarian and early-Imbrium basins on the Moon with reasonably well-constrained ages were formed. Some have argued that these basins were produced by a terminal cataclysm that caused a spike in the inner Solar System impactor flux during this interval. Others have suggested the basins were formed ...

Disinfection of surface drinking water, in particular water chlorination, produces many by-products with genotoxic and/or carcinogenic activity. The aim of this research was to evaluate the genotoxicity of surface water after treatment with different disinfectants by means of in situ plant genotoxicity assays. The study was carried out in a pilot plant using lake water after sedimentation and f...
