Definition
Luxullianite is a rare type of granite, known for presence of clusters of radially arranged acicular tourmaline crystals which are enclosed by phenocrysts of orthoclase and quartz in a matrix of quartz, tourmaline, alkali feldspar, brown mica.
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite

Etymology
From the village of Luxulyan in Cornwall, England, where this variety of granite is found
From oo- + -lite, after German Oolit. A rock consisting of fine grains of carbonate of lime

Archaeological Significance
Formation
Luxullianite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture. It is found in large plutons on the continents, i.e. in areas where the Earth's crust has been deeply eroded.
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.
