Pure obsidian actually has a glassy texture (grain), with no discernible crystalline structure.

Grain shape.
Three characteristics of a rock's grain include size (fine, medium, coarse), shape (angular, rounded), and sorting (well-sorted, poorly sorted). These characteristics can provide information about the rock's origin and history.
The grain shape of marble is typically interlocking. This means that the individual mineral grains in the marble are tightly interwoven or interlocked with each other, forming a solid and dense structure.
Shale grain shape refers to the physical form and texture of the individual particles within shale rock. These grains are typically small, often less than 0.0625 mm in diameter, and can exhibit various shapes, including platy, elongated, or rounded forms. The shape of shale grains is influenced by the processes of sedimentation and diagenesis, affecting the rock's porosity, permeability, and overall mechanical properties. Understanding grain shape is essential for interpreting the depositional environment and the geological history of shale formations.

Pellet grain is really just the type of shape of the grain. Instead of flake grain it is just shaped like a pellet or, if you will, like a perscriptian drug.

Yes, granite's grain shape is jagged.
The crystal form is hexagonal, but the grain shape is rounded.
A grain silo is typically cylindrical in shape. This design allows for efficient storage and easy unloading of grain, as the round structure helps facilitate the flow of grain towards the discharge point at the bottom. Some silos may also have conical or flat roofs, but the primary body remains cylindrical.
