Exempel på hur man kan använda TUFFACEOUS i en mening

• Rock that contains greater than 75% ash is considered tuff, while rock containing 25% to 75% ash is described as tuffaceous (for example, tuffaceous sandstone).
• The core part of the Arabika Massif is composed of the Upper Jurassic succession resting on the Bajocian Porphyritic Series, which includes sandstones, clays and conglomerates at the top, and tuff, tuffaceous sandstones, conglomerates and breccia, porphyry and lava.
• These Paleozoic rocks are overlain by Late Cretacecous coal-bearing argillites and quartzite-like sandstones and basaltic lava and tuff with lenses of tuffaceous argillite.
• 60 and 70S, fringing the East Antarctic Craton behind the active Panthalassan margin of southern Gondwana, being dominated by two types of facies: coarse- to medium-grained sandstone and tuffaceous rocks & minerals on the fluvial strata, which suggest the deposits where influenced by a large period of silicic volcanism, maybe more than 10 million years based on the thickness.
• The Pagoda Tillite is overlain by the MacKellar Formation (140 m) of interbedded black shales and fine sandstones, the Lower Permian Fairchild Formation (220 m) arkosic sandstone, the Upper Permian Buckley Formation (750 m), the Middle-Lower Triassic Fremouw Formation (650 m), the Upper-Middle Triassic Falla Formation (530 m), and the Jurassic Prebble Formation (0–460 m) volcanic conglomerate, tuff and tuffaceous sandstone.
• The group contains volcanogenic conglomeratic sandstone, fine-grained tuffite and tuffaceous sediment.
• The upper beds contains considerable latite to andesite breccia interbedded with tuffaceous claystone and siltstone.
• Member B: Light-gray, light-greenish-gray, light-brown, and light-purple, mudstone and claystone with interbeds of greenish-gray, yellow, and brown fine-grained sandstone, and minor conglomerate and tuffaceous beds.
• The tuffaceous sandstones, diatomaceous siltstones, conglomerates and dolomites were deposited in a lagoonal to near-shore environment, in bays similar to other Pacific South American formations as the Bahía Inglesa and Coquimbo Formations of Chile.
• 'Uranium occurs as a pitchblende and uraninite in a wide variety of deposits in granites and pegmatites, as disseminations in quartzites, as veins and disseminations in argillites and tuffaceous units, in shear zones and faults, and in granulites'.
• In the Seaham area the formation consists of 600mm of tillite, varved shale, aqueo-glacial conglomerate, tuffaceous sandstone, and mudstone.
• The age of the uppermost argillaceous part of the third deglaciation sequence (297 Ma) was determined from zircons of a tuffaceous bed sampled in a roadcut in the Western Cape Province, South Africa.
• In the late Cretaceous, kimberlite, carbonatite, olivine melilitite and tuffaceous diatreme intruded the Sao Francisco Craton.
• The formation consists of a shallow marine sandstone member containing many fish fossils, among which megalodon, and a deep water member comprising tuffaceous shales and mudstones containing gastropods, bivalves and scaphopods.
• The formation comprises the "Rodados Lustrosos" level, formed by clastic heterogeneous conglomerates in a silty matrix, considered as the stratigraphic evidence of the Pehuenche orogenic phase of the Andean orogeny, followed by uniform sequences, variable in thickness, of whitish-ocher tuffaceous paleosols with concretions and whitish-gray tuffs with intercalations of pyroclastic deposits.
• Finally, the upper member is represented by more homogeneous levels of tuffs, whitish gray tuffites, siltstones, green claystones and tuffaceous sandstones This member, in some sectors, is laterally interdigitated with marginal marine levels of the Gran Bajo del Gualicho Formation, which dates from the Late Oligocene to the Early Pliocene.
