What is the hardest type of sedimentary rock? Strongest Sedimentary Rocks. There are four types of sedimentary rock in Table 1: Sandstone, Shale, Limestone, and Dolomite. Of those four sedimentary rocks, Limestone and Dolomite tend to be the strongest sedimentary rocks, with the edge likely going to Dolomite.
Sedimentary rocks are layered rocks that are composed of accumulated sediments. Erosion and deposition play a key part in the formation of sedimentary rocks. Wind, water, ice, and chemicals break down existing rock into sediment that is then transported and deposited by wind, water, and glaciers.
Slate. Slate is a fine-grained, foliated, homogeneous, metamorphic rock derived from an original shale -type sedimentary rock composed of clay or volcanic ash through low-grade, regional metamorphism.
