Confusion of grain size and min-eral composition is especially pro-nounced in the usage of the term "gray-wacke," which has been applied indis-criminately to all clayey sandstones (a textural category), regardless of the min-eral composition of the sand portion. In addition to mineral composition and grain size, there is a third importantSandstone is composed of sand-sized (0.0625…2 mm) mineral grains, rock fragments, or pieces of fossils which are held together by a mineral cement. 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.Mudstone Mudstone is an extremely fine-grained sedimentary rock consisting of a mixture of clay and silt-sized particles. Terms such as claystone and siltstone are often used in place of mudstone, although these refer to rocks whose grain size falls within much narrower ranges and under close examination these are often technically mudstones.Compared to the Xin’anbian area, the grain size of the Chang 7 reservoir in the Heshui area is finer, generally consisting of fine siltstone grains (Figure 11a).
