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.

More about Basaltic Trachyandesite and Oolite
Here you can know more about Basaltic Trachyandesite and Oolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basaltic Trachyandesite and Oolite consists of mineral content and compound content. The mineral content of Basaltic Trachyandesite includes Olivine, Plagioclase, Pyroxene and mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt. You can also check out the list of all Igneous Rocks. When we have to compare Basaltic Trachyandesite vs Oolite, the texture, color and appearance plays an important role in determining the type of rock. Basaltic Trachyandesite is available in black, brown, light to dark grey colors whereas, Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. Appearance of Basaltic Trachyandesite is Dull and Soft and that of Oolite is Rounded and Rough. Properties of rock is another aspect for Basaltic Trachyandesite vs Oolite. The hardness of Basaltic Trachyandesite is 6 and that of Oolite is 3-4. The types of Basaltic Trachyandesite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite whereas types of Oolite are Pisolitic Oolite and Oncolitic Oolite.
