Litharenite and lithic quartz sandstone are the main rock types. Compaction is concluded by former researchers as the control factor of low permeability. Examination through thin section reveals that secondary pores developed well in coarse sand. Inter-granular dissolution is included as the positive effect to increasing.

Sandstone - Geology - rocks and minerals

The cement that binds the clasts can vary from clay minerals to calcite, silica or iron oxides. Sandstone can be further divided according to: Clast size - fine (0.06-0.2mm), medium (0.2-0.6mm), coarse (0.6-2mm);. Sorting - a sandstone comprising a mixture of clast sizes is poorly sorted, while one comprising mostly clasts of.
