Definition

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

Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface

History

Formation

Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.

Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
