Tabular uranium deposits are typically sandstone-hosted and chemically and genetically similar to roll-fronts. The main difference is their morphology, in that tabular ore bodies are generally parallel to the bedding of the host rock. Like roll-fronts, tabular ore bodies also form as a result of groundwater flow, but occur when the reducing ...

During the 1960's and the 1970's the Liedena Sandstone was a type deposit for “flysch-like facies” (sandstone and lutite alternations) of coastal sedimentary systems. However, the depositional system of these beds was never accurately defined. The sedimentological analysis along 100 km of outcrops in the western part of the South Pyrenean Zone (Navarre) allows these peculiar facies to be ...

Precambrian sandstone deposits. Considerable deformation is evident at the structure and in smaller, isolated outcrops in the vicinity. Deformation involves major and minor faulting, folding, shearing, missing stratigraphic units, brecciated dolomite, and beds with varied strikes and dips, with some of these beds being pitched near vertical.

Significant sandstone-uranium deposits are located in fluvial (or river) sediments filling ancient river channels known as paleochannels. These often occur within buried valley systems cut into bedrock which are known as paleovalleys.

Aug 14, 2019 Sandstone Basics. 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.
