No scheme has found universal acceptance, and ...Concretions are hard bodies that form in sediments before they become sedimentary rocks. Slow chemical changes, perhaps related to microbial activity, cause minerals to come out of the groundwater and seal the sediment together. Most often the cementing mineral is calcite, but the brown, iron-bearing carbonate mineral siderite is …The characteristics and distinguishing features of clastic sedimentary rocks are summarized in Table 6.2.

Weathering and erosion of rocks like granites concentrate elements that are necessary to form clay minerals, which accumulate as sediments. The deposition and burial of clays, in the delta of a river, for example, lead to the formation of the sedimentary rocks claystone and shale. Weathering and erosion ... In order for a rock to be considered a claystone, it must consist of up to fifty percent clay, which measures less than 1/256 of a millimeter in particle size — more than half of the composition is clay-sized particles. Claystone Mudstone Mudstones and shales are made of silt- and clay-sized particles that are too small to see.The porosity of 46% in the confined bentonite and 26.5% in the confined claystone/bentonite mixture were fully saturated with the respective maximum amounts of water uptake, while the confined claystone aggregate with a porosity of 24% could be partly saturated with the maximum water uptake of 5% to a saturation degree of 45%.

Fair-sorted rocks contain 75 to 90 percent silt or clay. Poorly sorted siltstone or claystone contains less than 75 percent silt or clay. If fissile, fine-grained clastic rocks are so designated. The mineral composition of most fine-grained clastic rocks can be determined reliably with the petrographic microscope and by X-ray diffraction.

The rocks consist of dark grey claystone, laminated claystone and fine-grained sandstone with common bioturbation, into fine-grained, which grades into lithic sandstone of possible lower delta-front environment (Yoo et al., 1995, p. 238; Yoo et al., 2001, p. 40).
