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

Closely piling up of multiple adhesive fronts in adhesive friction due to re-attachment [PDF]
arXivAs a fundamental force, friction exerts a profound influence on various aspects of our daily lives across multiple disciplines. To understand why adhesive friction is associated with the contact area, here we investigate the generic sliding of elastic solids adhered to a rigid surface by considering re-attachment/healing.

Blasting effects of cross‐fault deep‐buried excavation on adjacent existing tunnel stability
Deep Underground Science and Engineering, EarlyView.Based on the theoretical analysis of cylindrical wave propagation in a deep rock mass in the fault with a filling layer, the calculation method of peak particle velocity caused by wave propagation in the existing tunnel is established. The viscoelastic characteristics of a rock mass are examined in the analysis.

Deep Underground Science and Engineering, EarlyView.In this study, the nonuniform distribution of the bearing pressure in front of the coal wall has been revealed based on in situ monitoring data and numerical simulation results. Therefore, an eccentric compression mechanical model of the coal wall was established to study the deformation and failure characteristics of a coal wall. The slenderness ratio
