Mudrock - Wikipedia

Clay is by far the smallest particles recognized in mudrocks. Most materials in nature are clay minerals, [clarification needed] but quartz, feldspar, iron oxides, and carbonates can weather to sizes of a typical clay mineral. For a size comparison, a clay-sized particle is 1/1000 the size of a sand grain.

weathered by a process that strips ions from their structure leaving behind only aluminum and silicon oxides/hydroxides – clay minerals. Clay minerals are tiny sheet silicates (like mica). Because feldspars (and other aluminosilicates) are the predominant minerals in crustal rocks that serve as parents for sediment, clay is the most common

How Is Mica Formed? | Reference.com

How Is Mica Formed? There is no definitive evidence to fully explain the formation of mica as the process is still under scientific study as of 2015. However, mica formation is said to be closely associated with the lack of orthoclase feldspar in pegmatites, which is where the mineral is predominantly found.
