Definition
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel
Adamellite is a coarse-grained porphyritic igneous rock, a variety of Monzogranite and dominated by phenocrysts of orthoclase in a granular groundmass of perthite, plagioclase and quartz
