Sandstone description.

Aug 13, 2019 · Sandstone is a type of rock made from sediment — a sedimentary rock. The sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock. It is composed mostly of sand particles, which are of medium size; therefore, sandstone is a medium-grained clastic sedimentary rock. The Potsdam Sandstone is composed of tiny quartz (SiO2) grains that are held together by quartz cement. The result is a very hard, compact and weather-resistant rock. Smash a piece and the fracture will cut across both the cement and individual sand grains. Such well-cemented, pure quartz sandstones are called orthoquartzites by geologists ...Description: These are very-well-sorted, fine- to medium-grained sandstones showing weak planar, irregular and inclined stratification, and localized burrows and rootlets. The sandstones are typically preceded by upper shoreface sandstones and are commonly succeeded by, and interdigitated with, lagoonal deposits.Description and Interpretation of Lithofacies Types Each lithofacies is described and interpreted as follows: 1. Lithofacies (H1): Small to large-scale cross-bedded sandstones Description This lithofacies consists of up to 95% clean, fine to medium-grained sandstones present in cores # 7, 8 and the upper part of 9 (Figs. 6 & 7).

banded gneiss. Gneiss is the principal rock over extensive metamorphic terrains. The banding may be oriented nearly parallel to the Earth’s surface (horizontal dip) or may have a steep dip. Such orientations can be interpreted in terms of the stresses that prevailed during the formation of the rock. Gneiss can be classified on the basis of ...

The Lyons sandstone consists of purely quartzose sandstone. It is best developed at Lyons (a few miles north of Boulder district as mapped), where it is quarried in large amounts.
