Flint sedimentary rock
WebAbstract. Flint clay is kaolinitic mudstone that distinctively differs from widely known shale in lithology, genesis, and economic uses. Flint clay is described as a fine-grained, compact, non-fissile, essentially monomineralic kaolinitic rock that breaks with a conchoidal ("flinty") fracture, has almost no natural plasticity, and resists slaking. http://geologyscience.com/category/rocks/sedimentary-rocks/non-clastic-sedimentary-rock/
