Definition
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
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel

Archaeological Significance
Formation
Adamellite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma and is a variety of Monzogranite.
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
