Multi-scale evaluation of mechanical properties of the Bakken shale
Understanding mechanical properties of shale has been the topic of research in the past decade due to its importance in hydraulic fracturing and rock physics modeling. Since shales are highly heterogeneous in constituent components, detailed understanding of mechanical properties in a multi-scale (nano, micro, macro and field) is vital and can present …

KGS--Kansas Rocks and Minerals--Minerals
Minerals with a hardness of 6 or more will easily scratch a piece of glass. A sample such as calcite is too soft to scratch glass but is hard enough to scratch a fingernail. Therefore it has a hardness between 6 and 2.5. Hardness is another clue in identifying minerals, and in this book the hardness for each mineral is listed alongside its name.

Black shales
The content of organic matter rarely exceeds a few percent; when it is considerably higher the rock may yield petroleum upon distillation and hence can be described as oil shale. Structureless and chemically inert kerogen dominates, but there is a variable admixture of terrestrially-derived spores, pollen and woody matter together with non ...
