Tensile Strength of Artificially Cemented Sandstone Generated via Microbially Induced Carbonate Precipitation
Artificially bio-cemented sands treated with microbially induced calcite precipitation are weakly cemented rocks representing intermediate materials between locked and carbonate sands. Variations in cementation significantly...
The Sands of Time: Understanding the Roles and Effects of Turbidity Flow Velocity on Grain Size and Grain Alignment Within Recent and Ancient Turbidite Deposits

Microstructural evidence for crystallization regimes in mafic intrusions
The magma forming the 20 m thick crinanitic/picrodoleritic Dun Raisburgh sill, part of the Little Minch Sill Complex of NW Scotland, comprised a mafic carrier liquid with a crystal cargo of plagioclase and olivine (1 vol%). The...
