Oolitic & Pisolitic structure: These are examples of concretionary structures. In oolitic structures, the concretions are of the size range 0.1 to 1.00 mm. In Pisolitic structure, the individual size of the concretion is like that of a peanut, greater than 1mm. Eg: oolitic and Pisolitic limestones. Texture of Metamorphic rocks i. Many Proterozoic oil deposits are attributed to the activity of cyanobacteria, such as Gloeocapsomorpha.Small concentrically layered structures called pisolites are also the result of fossilized bacteria. Cyanobacteria are otherwise rarely preserved in rocks other than chert, though some possible blue-green bacteria have been recovered from shale.
