What is shale rock.
If shale has less swelling clay minerals but more silica, carbonate and feldspar, the rock is highly brittle and likely to be fractured. In shales with identical mineral compositions, the finer the grain size, the more conducive to fracture development it is, and vice versa (Zeng and Xiao, 1999, Li et al., 2009).

It is a find-grained rock made up of mud comprised of flakes of clay and other minerals such as quartz and calcite. The resulting rock breaks readily into thin layers called fissility. Expanded shale is found in areas like Texas 10-15 feet (3 to 4.5 meters) below the soil surface.
Reservoirs are typically porous sandstones, limestones or dolomite rocks, but also include "unconventional reservoirs" such as shale rock or coal beds.

Shale is the most common sedimentary rock, accounting for about 70 percent of the rock found in the Earth's crust. It is a fine-grained clastic sedimentary rock made of compacted mud consisting of clay and tiny particles of quartz, calcite, mica, pyrite, other minerals, and organic compounds.
Shale, on the other hand, has very fine grains and often breaks into fragments. Conclusion. Sandstone is a sedimentary rock mainly made of sand or quartz grains while shale is a finely stratified sedimentary rock of silt and clay-size mineral particles. Thus, this is the main difference between sandstone and shale.
