Some features of composition and genesis of terrigenous rocks of kolganskaya strata

open access: yesRUDN Journal of Engineering Research, 2012
The article is about Upper Devonian kolganskaya strata formed in delta front. Gamma-active benchs presented by clay deposits, were marked at the bottom of the kolganskaya strata, and its may be a good cap-rocks for the lower-lying rocks.

Factors controlling rock-clay buffer interaction in a radioactive clay repository

open access: yes, 2020
The paper examines the interaction between host rock and a clay-based engineered barrier in the context of deep underground disposal of high-level radioactive waste. A large scale “in situ” heating test currently under way in the underground Grimsel Rock Laboratory (GRL; Switzerland) is adopted as a representative case for study.

Mineral reconnaissance at the Highland boundary with special reference to the Loch Lomond and Aberfoyle areas [PDF]

open access: yes, 1983
Serpentinite bodies at the Highland Boundary in the Loch Lomond and Aberfoyle areas are extensively altered to magnesite-quartz and ferroan-dolomite-quartz rocks. Silicification was probably initiated before conversion to carbonate.
