That's the armature.
it is called SHALE :)
The material formed is called till. The structure formed is called a moraine.
claystone
shale
The Clay Belt of the Canadian Shield formed when the Glacial Lake Ojibway drained around 8,200 BP. The lakebed sediment is the source of soil in the clay belts.
The sedimentary rock formed from tiny particles of clay in thin, flat layers is called shale. I hope this was helpful:)
they were formed when the lakes were frozen in the glaciers. Then as they resided, the clay belts were formed.
Claystone, and shale are sedimentary rocks formed from lithified deposits of clay.
clay is formed by weathering( hydrolysis,decomposition and hydration) of igneous rock which has feldspar as its major component.
Clay is formed from rocks by those rocks being weathered to minute particles, those particles being washed in a river and then deposited. As clay is formed of these "sediments" it is sedimentary.
The sedimentary rock formed from clay deposits is called shale. Shale is composed of very fine particles of clay minerals that have been compressed and compacted over time. It commonly has a layered structure due to the alternating sequences of clay-rich and silt-rich layers.
It is more accurate to say it is formed from clay and silt.
