Definition
Whiteschist is an uncommon rock type belonging to a class of metamorphic rock, this is formed at high-ultra-high pressures
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel

Features
High percentage of mica, Host Rock for Lead
Clasts are smooth to touch, Easily splits into thin plates, Has High structural resistance against erosion and climate
Archaeological Significance
Formation
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
