1.1 Definition
Phonolite is an uncommon extrusive igneous rock volcanic rock of intermediate chemical composition between felsic and mafic
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite
1.2 History
1.2.1 Origin

1.3 Etymology
From the Greek meaning sounding stone because of the metallic sound it produces if an unfractured plate is hit
From oo- + -lite, after German Oolit. A rock consisting of fine grains of carbonate of lime

5.1 Formation
Phonolite are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.
