文摘
- •
Samples show shale microstructures with silt-sized grains embedded in a fine grained matrix.
- •
Quartz content is homogeneous throughout the basin, whereas the carbonate content varies.
- •
Northern European Toarcian shales fall within the carbonate, mixed and argillaceous mudstones.
- •
No evidence was found that outcrop samples are microstructurally more altered than core samples.
