Modification of clays subjected to different stages of lithogenesis under microbial activity
Abstract A comparative study of the influence of microorganisms on physical-chemical clays’ properties at different lithogenetic stages concerned the formation of contact strength between particles was carried out. Natural samples were taken for experiments: dolomite-clay marl from outcrop, the Jaho...
