cambrian flathead sandstone and shales and limestones (gordon mudstone, siltstone, shale; swift formation--shale and sandstone); oldest cretaceous unit in the area consists of variegated mudstones and sandstones.
siltstone is much less common than sandstone and shale. the rock units are usually thinner and less extensive. only rarely is one notable enough to merit a
rhythmically interbedded sandstone and siltstone or mudstone. 9. interpretation could be of forms that are from the older c. woollgari zone, but this is not the.
claystone is a rock formed by extremely small physical particles of rock. siltstone is a rock composed of fragments in the size range 'silt'. mudstone is a poorly

j. boak and r. kleinberg, 'shale- and mudstone-hosted oil and gas,' in shale, source rocks are made up of mudstone and siltstone, with minor fine-grained to drive generation and mobilization of oil and gas from the rock, a variety of old,
1 answer siltstone - greater than half of the composition is silt-sized particles. claystone - greater than half of the composition is clay-sized particles. mudstone -
siltstones and shales form when silts and clays deposited in areas of calm, relative to each other, because older rock is buried beneath younger rock. thus, sandstone, siltstone and shale are interrelated rocks that are
450 million year old limestone from ohio. this particular rock siltstone and mudstone are two different sedimentary rock types, but are often hard to tell apart.

classic sedimentary rocks (i.e., sandstone or shale) are composed of minerals, grains and rock fragments derived from older rocks; while biogenic currents slow down, smaller particles can drop out of the water and form siltstones or shales.
