Argillite - an overview | ScienceDirect Topics Argillite is defined as rhythmically laminated, muddy-siltstone facies that grade into mudstone, typically found in marine environments and characterized by soft sediment deformation structures and interbedding with other sediment types AI generated definition based on: Sedimentary Geology, 2012
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
Orogenic gold in the Blue Mountains, eastern Oregon, USA Highlights • Scale-integrated mineral system for orogenic gold in the Blue Mountains • Historically-rich veins along crustal-scale terrane boundaries and near plutons • Production value correlated to dilatant zones within left-lateral strike-slip faults • Most gold hosted in lower greenschist facies argillite, schist, and slate • Structural intersections with host rock and
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
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
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
Permeability of macro-cracked argillite under confinement: Gas and . . . Argillite is considered a privileged candidate for long term nuclear waste storage Yet argillite rock drilling often induces surface cracks that locally modify its permeability This phenomenon located in a so-called Excavation Damaged Zone (EDZ) is of importance since permeability increase means lesser confinement capacity of the argillite rock
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
Sedimentary Geology and Stromatolites of the Middle . . . - ScienceDirect The Appekunny Argillite is ∼700 m thick, consists largely of green-colored, fine-grained terrigenous material and appears to have been deposited predominantly in offshore and or deltaic settings The overlying Grinnell Argillite is 605 m thick and consists of red-colored terrigenous material deposited largely on an alluvial plain
