1] Flood basalts are a potentially important host medium for geologic sequestration of anthropogenic CO 2 Most lava flows have flow tops that are porous and permeable and have enormous capacity
·The striking similarity of the composition and tectonic distribution of the alkali basalts from eastern China with those of the central western Europe and southeastern Australia Pilet 2015 indicates that the mechanism of carbonate melt fluxed eclogite melting and subsequent melt rock reaction Mallik and Dasgupta 2013 may also apply to
·Basalt volume calculations are based on a detailed study of 58 boreholes selected from >100 boreholes based on available data quality and field sections across the Tarim Basin Figures 1b and 3a These data were collated into a database of basalt thicknesses Supporting Information S1 and used to generate basalt isopach map
·It is a known fact that fiber distribution has an effect on strength development and mechanical properties [74][75][76][77][78] Since the cementitious mixture is water based the homogeneous
·The Mesozoic rift basins of northeast China are characterized by a significant proportion of basalt due to the progressive emplacement of basalt lava flows The objective of this study was to construct vesicle distribution models of the basalt lava flow units including conceptual geological models and thickness models to understand the architecture of the

·This study aims to i determine the concentrations and distribution of heavy metals As Cd Cr Cu Hg Ni Pb and Zn in basalt bedrock basalt derived topsoil and cultivated crops; ii assess the potential human health risks associated with heavy metals in food crop grains and iii investigate the cumulative characteristics and
·The results from the above mentioned methods have shown that the distribution of the eruptive volcanic basalt is mainly concentrated along the South China Sea s sea floor spreading axis
·The red soil laterite in subtropical to tropical southern and southeastern China provides important terrestrial archives of palaeoclimate and palaeoenvironment Liu et al 2012b Liu et al 2010 We present a detailed environmental magnetic investigation of a basalt weathering profile formed in a tropical climate
·The North China Craton NCC is considered to be a collage of four micro continental blocks including the Yinshan Ordos Longgang and Rangrim blocks A detailed introduction to the principle of RF can refer to Breiman 1996 Breiman 2001 this also shows the same zonal distribution as the basalt trend in the study area
·2 Geological Setting and Sampling Site U1365 is located in the western margin of the South Pacific Gyre ∼800 km to the east of the Tonga Kermadec trench Figure 1 The crust at Site U1365 was accreted during the Cretaceous Superchron 84 120 Ma from the Osbourn trough with a medium to fast spreading rate [Zhang et al 2012] However the basement age
Alkali basalt is a fine grained dark color volcanic rock composed of phenocrysts of olivine titanium rich and iron oxides Fig Alkali basalt is relatively poor in silica and rich in sodium It is silica unsaturated and contains feldspathoids nepheline leucite alkali feldspar and phlogopite magnesium mica in the groundmass
·Based on the spatial temporal distribution of different rock series and the spatial distribution of varied metamorphic grades of the Neoarchean in different regions of the Eastern North China craton we propose that the craton can be divided into four blocks the Lushan Jiaobei Zhongtiao Taishan Liaonan Qingyuan and Wutai Zunhua blocks
