Chert is in most cases a biogenic rock, it is made of siliceous tests of diatoms, radiolarians, siliceous sponge spicules, etc. Sometimes microscopic fossilized remains of these sea creatures may be preserved in these rocks. ded chert. And it is in fault contact with Pak Pat volcanic rocks. Both of Pha Som Metamorphic Complex and Pak Pat volcanic rocks are covered by the Upper Triassic and the Jurassic red sandstones with angular unconformity.
