Definition
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel
Litchfieldite is a rare igneous rock which is coarse-grained, foliated and a variety of nepheline syenite, sometimes also called as nepheline syenite gneiss or gneissic nepeheline syenite

Formation
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
Litchfieldite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
