Definition
Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite

Etymology
From its mineral and compound content and its relation with Basalt and Andesite rock
From oo- + -lite, after German Oolit. A rock consisting of fine grains of carbonate of lime

Archaeological Significance
Formation
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
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.
