Stratification
Foliated rocks have layers in them. We often refer to the layers as Banding.
Most igneous rocks have a relatively homogenous mix of minerals which are interlocked.
Sedimentary rocks are composed of layers, and show how layers have built up over time. Hope this helps!
Sedimentary rock. It forms when layers of sediment pile up.
stratification
Sedimentary rocks are the type of rocks that are mostly arranged in layers. The way in which the layers are arranged is commonly called bedding.
Stratification
The descriptive term is foliated.
Strata refers to distinct layers or divisions within a rock formation or other material. Stratification refers to the process of arranging or forming these layers. In essence, strata are the actual layers, while stratification is the process of layering.
Rocks with grains arranged in parallel layers are called sedimentary rocks. These rocks form when sediment such as sand, mud, or organic material is deposited and compacted over time. Examples include sandstone and shale.
Strata are layers of rock or sediment that have been deposited over time. They are arranged in a sequence, with the oldest layers at the bottom and the youngest layers at the top. This arrangement is known as the principle of superposition, which states that in any undisturbed sequence of rock layers, the oldest rocks will be at the bottom and the youngest rocks will be at the top.
Magma that has fallen out a volcano to make sediments through metamorphism.
Metamorphic rocks such as marble and quartzite are said to be non-foliated because their mineral grains are not arranged in parallel layers or bands like in foliated rocks such as slate or schist. This lack of alignment gives non-foliated rocks a more uniform texture and appearance.
Each layer is deposited over time as the environment changes over millions of years. The process is deposition of differing sediments, forming strata. When buried at great pressure, the rock is formed, and the strata are evident. Layers may also be caused by lamination of the sediments or through mineral banding (especially in sandstones).
Metamorphic rocks with a layered or banded look are referred to as foliated.
