Definition
Borolanite is a variety of Nepheline Syenite and belongs to igneous rocks and contains nepheline-alkali feldspar pseudomorphs which occur as conspicuous white spots in the dark rock matrix
  
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel

Formation
Borolanites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
  
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
