Local intervals of colluvium. The roof of coal seams are mostly soft rock with weak cementation. The reservoir rock types include shale, siltstone, sandstone, limestone, dolomite and even volcanic rocks. Siltstones are intermediate between sandstones and shales but are not so . It represents a level of current, wave, or wind energy between where sand and mud accumulate. It is also long-lasting and stands up well to exposure. For example, breccia rocks are often rather . quality 1584 Yield 1. Silt is made up of rock and mineral particles that are larger than clay but smaller than sand.Individual silt particles are so small that they are difficult to see. Figure 4 shows the stress-strain curves of intact siltstone, plain coal, and jointed siltstone with a coal layer thickness of 5, 10, 15, and 20 mm. Siltstone is deposited in a similar environment with shale, but is usually located near the old delta, lake or sea shore, where calm currents cause less particle suspension.Siltstone is generally formed adjacent to sandstone deposits - ie close to beaches and delta edges where sand is deposited. Silt is a solid, dust-like sediment that water, ice, and wind transport and deposit. It is a mixture of micas, quartz, feldspars, and clay minerals.
