  • Argillite - an overview | ScienceDirect Topics
    These rocks form Transvaal Supergroup (Pretoria Group) comprising argillite, shale, quartzite, banded-hematite–quartzite (BHQ), and dolomite The total overlying sequence is covered by Early Proterozoic volcanic flows and pyroclastics (Rooiberg Suite), a precursor of the ultramafic intrusion forming the roof of the Igneous Complex
  • Argillite - an overview | ScienceDirect Topics
    Argillite is defined as a type of sedimentary rock that contains a significant amount of clay minerals, including smectite, which contributes to its very low permeability and high capacity for retaining radioactive elements This rock formation is utilized in deep geological disposal studies due to its stability and ability to contain radioactivity over the long term AI generated definition
  • Redox-sensitive trace metal hyper-enrichment in . . . - ScienceDirect
    In this contribution, we studied the redox-sensitive metal distribution and accumulation mechanisms in graptolite argillite successions in NW Estonia Our aim was to provide better constraints on redox and depositional environments in the Baltic Palaeobasin
  • A study on the dynamic behavior of the Meuse Haute-Marne argillite
    The Callovo-Oxfordian argillite (clay shale) investigated by ANDRA is a sedimentary rock without significant anisotropic material properties (Hoteit et al , 1999, Su et al , 2003) Drill-and-blast excavation method is the principal method used by ANDRA during the construction of the Meuse Haute-Marne Underground Laboratory
  • Temperature stability of an argillite K-geopolymer composite: Impact of . . .
    This explains why the material formulated and studied here is an argillite K-geopolymer composite (i e a baked argillite-based alkali-activated geomaterial) incorporating various different filler quantities
  • Effects of pre-existing cracks and infillings on strength of natural . . .
    However, for the argillite and basalt, it was rather difficult to create pre-existing cracks deeper than 1 cm without fracturing the whole specimen For this reason, both argillite and basalt contained pre-existing cracks with the depth of only 1 cm
  • A MAS-NMR analysis of - ScienceDirect
    A MAS-NMR analysis of 29 Si, 27 Al and 1 H on the temperature's impact on geopolymer grouts derived from argillite and metakaolin
  • Orogenic gold in the Blue Mountains, eastern Oregon, USA
    Argillite, schist, and slate formed in accretionary wedge and fore-arc basins host the majority (∼60%; ∼29 t) of the total recorded gold production Unique geochemical, geomechanical, and hydrological properties made these rock types excellent hosts
  • Coupled THMC models for bentonite in an argillite repository for . . .
    An engineered barrier system (EBS) that includes a bentonite-based buffer is widely used in the multi-barrier system designs for geological disposal of radioactive waste throughout the world Argillite is one of the candidate host rocks that have been extensively studied in various countries, especially in Europe
  • Curing temperature’s effect on argillite-metakaolin based geopolymer . . .
    In contrast, for argillite or argillite-metakaolin based samples, a decrease of pore size as well as in pH values were observed with the increase of temperature This behaviour was attributed to the dissolution of argillite’s impurities such as illite, providing more oligomers to allow the formation of different geopolymer networks
