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. Reference: 1. “Shale.”In general, the particle size of sediments is larger in sedimentary deposit deposited in high-energy environments. Fine-grained sediments tend to erode in high energy environments, and tend to be deposited in low energy environments. In addition, the higher energy environments tend to have higher dissolved oxygen and nutrient concentrations ...Shale is a tightly packed sedimentary rock. The shale is very porous, but it is not very permeable. This allows the shale to hold a lot of oil/natural gas but makes it difficult to remove those energy sources.
