Shale is non foliated, as foliation is a rock texture caused by metamorphism; fluid drag or crystal settling in igneous magmas and lavas, whereas shale is a sedimentary rock typically deposited in lacustrine or other low energy environments.
The banding in shale is called lamination and is due in part to variations in the energy of the depositional environment, leading to fluctuations in the size of grains being deposited and also due to the presence of large numbers of clay minerals which are typically plate like (termed phyllosilicates) and therefore on compaction form parallel layers.
No. Shale is laminated. It is a sedimentary rock. Foliation is a characteristic of metamorphic rock.
Slate, being a foliated rock, has a layered structure that makes it easier to break along those planes of weakness. In contrast, quartz is a non-foliated rock with a more uniform structure, making it generally more resistant to breaking. Therefore, slate would be easier to break compared to quartz.
Foliation occurs deep underground.
Shale
No, shale rocks are not typically attracted to a magnet because they are composed primarily of clay minerals and other non-magnetic materials. Magnetism is generally not a characteristic of shale rocks.
Shale is a noun.
It can be. It is found in a rock type called shale and is produced in the shale form the original bio mater included in the deposition of the shale. If a unit of shale lithology is to be found on the continental shelf strata then it is likely that that shale will contain shale gas and it will be under the sea.
The Shale is not a metamorphic rock it is a sedimentary rock.
No, shale is clastic.
Shale.
No, shale is not magnetic.
Another name for shale is mudstone
