The size of the individual particles that make up these rocks are very small.
Shale turns into slate through a process called metamorphism, where heat and pressure transform the shale's minerals into new minerals like mica and chlorite. This process also causes the shale's original clay minerals to recrystallize, making it more compact and giving it a foliated texture characteristic of slate.
The chemical formula of shale is variable, as it is a sedimentary rock composed mainly of clay minerals, quartz, and other minerals. The general formula can be written as (Al,Si)3O10(OH)2, representing the presence of aluminosilicate clay minerals in shale.
Shale can sometimes contain magnetic minerals, such as magnetite or hematite, which can make it slightly magnetic. However, the magnetic properties of shale can vary depending on the specific mineral content and geological conditions.
Shale usually crumbles easily because it is composed of fine-grained clay minerals that lack cohesion. The rock's sedimentary nature means it has undergone compaction and cementation relatively less than harder rocks like sandstone or limestone. This makes shale prone to breaking into small pieces when stressed.
The red color of the Queenston Shale in the Niagara Escarpment is due to the presence of iron oxide minerals, specifically hematite, within the rock formation. These minerals are responsible for the red hues seen in the shale.

Shale rock is primarily composed of clay minerals and small particles of other minerals like quartz and calcite. These minerals are compacted together over time to form the distinct layers of shale rock.
Shale is not an element. Shale is a type of sedimentary rock composed of clay-sized particles that have been compacted over time. It is made up of various minerals such as quartz, feldspar, and clay minerals.
Clay minerals, quarts, feldspar
== Shale is a sedimentary rock, comprised of lithified mud and clay minerals.

Minerals could include clays, feldspars, quartz, micas, and pyrite
