A rock structure is made out of any type of rock. A rock structure can be man made but is usually naturally made, caused by weather or erosion.
Basalt is defined as "a dark, fine-grained volcanic rock that sometimes displays a columnar structure. It is typically composed largely of plagioclase with pyroxene and olivine."
The way the pieces of materials in the rock fit together define its cycle. The rock cycle will entail the formation of the rocks with the various pieces of materials.
sedimentary rock has different layers called as bedding
Shale rock / Roof rock

Oregon's state rock is the thunderegg. However, geologists point out that it isn't really a rock; they define it as a "structure," either a nodule or a geode. When the Oregon Legislature designated the thunderegg as the state rock in 1965, they also decreed it to be an "honorary rock," thereby getting around this problem of definition.
Composition of minerals
the structure of an igneous rock is metamorphic rock that has been heated rapidly and turned into magma then cooled to create igneous rock its gay

The common structure of a metamorphic rock is that there are several pieces of different types of minerals, sand, rock, or glass.
