0 a type of rock that is made of sand or particles (= small pieces) similar to sand -- 粗屑岩
Many of the island's rocks have been identified as relatively quartz-rich arenites. 这座岛上大多数的岩石是石英含量相对较多的粗屑岩。
Arenite is a sedimentary rock. 粗屑岩是一种经沉积形成的岩石。
Most of these sedimentary rock fragments are coarse arenites or fine diamictites.
The composition of the arenites is given in Table 2.
Arenite is a sedimentary clastic rock with sand grain size between 0.0625 mm (0.00246 in) and 2 mm (0.08 in).
In sections from a proximal position relative to the palaeo-shoreline, the lower parts of this limestone are dolomitized and contain thin intercalations of quartz arenite.
Beds of very fine to very coarse, sandstone (volcanic lithic arenite) and mudstone dominate the succession with a bed of lithic and vitric tuff occurring at one horizon.
Six sandstone names are possible using descriptors for grain composition (quartz-, feldspathic-, and lithic-) and amount of matrix (wacke or arenite).
Beds of very fine to very coarse, rarely gravelly, sandstone (volcanic lithic arenite) and mudstone dominate the succession with beds of lithic and vitric tuff occurring at two horizons.
Sand composition is largely quartz arenite and a small percentage of monomineralic components dominated by quartz and some accessory minerals (zircon, feldspar, hematite, and rutile).
