It grades into siltstone, shale or mudstone (grains less than 0.0625 mm in diameter) and conglomerate (or breccia if the clasts are angular) if the average grain-size exceeds 2 mm 1. Igneous and sedimentary compositions are also often ambiguous due to minimal chemical weathering of igneous minerals across Mars—olivine has been found in mudstone (Vaniman et al., 2014)—which allows sediments and sedimentary rocks to have very reasonable igneous-like compositions (McLennan et al., 2014; Tosca & Knoll, 2009).Muscovite is found in igneous, metamorphic, and sedimentary rocks. In igneous rocks, it is a primary mineral that is especially common in granitic rocks. In granite pegmatites, muscovite is often found in large crystals with a pseudohexagonal outline. These crystals are called "books" because they can be split into paper-thin sheets.The classification and description of the various chemically formed sedimentary rock types appears in the bottom section of the chart below.
