Definition
Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite
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

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

Features
Available in lots of colors, Generally rough to touch, Very fine grained rock
Has High structural resistance against erosion and climate, Very fine grained rock
Archaeological Significance
Formation
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.
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

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