Limestone vs Shale - Compare Nature
1.1 Definition. Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate. Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles. 1.2 History.

Mudstone/Shale vs. Limestone - University of Pittsburgh
Mudstone/Shale vs. Limestone. Both limestone and mudstone/shale can ve very fine grained, so how do you tell them apart? Well, shales tend to break into thin, angular pieces whereas limestones tend to break into hard blocks. While mudstones also break into blocky pieces, they tend to be quite soft.
