Shale forms from muddy deposits that settle out in slow moving water, such as in deltas or along continental shelves. Sandstone forms from sandy deposits and limestone forms from deeper deposits. Shale is a mudrock—a classification of rocks that are composed mainly of silt-sized or clay-sized particles (both microscopic).A typical shale is composed of about 58% clay minerals, 28% quartz, 6% feldspar, 5% carbonate minerals, and 2% iron oxides. Most of the quartz is detrital (part of the original sediments that formed the shale) rather than authigenic (crystallized within the shale after deposition).Common Metamorphic Rocks: Common metamorphic rocks include phyllite, schist, gneiss, quartzite and marble.

Mudrock is composed of at least 75% silt- and clay-sized fragments. If it is dominated by clay, it is called claystone. If it shows evidence of bedding or fine laminations, it is shale; otherwise, it is mudstone. Mudrocks form in very low energy environments, such as lakes, river backwaters, and the deep ocean. It is composed of small particles of quartz, white mica, clay minerals, hematite and alunite. The striking colour banding was probably formed after the original sediments were deposited by the rhythmic precipitation of hematite-rich bands during alteration of the rock in a highly oxidising environment.
