Shale is a mudrock—a classification of rocks that are composed mainly of silt-sized or clay-sized particles (both microscopic).

Limestone’s most common use is as a crushed construction material, serving as a base for roads and ballast in railroads, but it also combines with crushed shale in a kiln to make cement and serves as an aggregate material in concrete. Limes...

Limestone is almost always marine (ocean water) in origin and is usually associated with other near shore rocks types. In a typical marine scenario, to the shore side of a reef is the silica mud of a lagoon and closer to shore is the sand of a beach. The silica mud will form a shale while the beach sand will form a sandstone.Six full-scale tests were performed on the aggregates and are listed in Table 1.Surface deformations of the completion layer and resilient pressures in the formation layer were measured during the cyclic loading for the following road structure arrangements and conditions: (i) 150 and 250-mm-deep layers of sandstone, and 250 and 400-mm-deep …Thus, we can deduce that the mudstone and shale are older than the rhyolite dike. But, since the rhyolite dike does not cut across the shale, we know the shale is younger than the rhyolite dike. In the diagram to the right,the fault cuts the limestone and the sandstone, but does not cut the basalt.Dalwood Group and lower Shoalhaven Group: calcareous sandstone, conglomerate, shale, limestone, lava flows and tuff.
