Carboniferous limestone
The most widely-distributed sedimentary rock is Carboniferous limestones, the main rock across much of the central lowlands. In most places the limestones are overlain by materials deposited during or after the last glaciation. In a few areas, however, the cover is thin or non-existent and a distinctive limestone landscape has developed.

The pelletal material exiting the kiln is called "clinker." Gypsum is added, and the clinker-gypsum mixture is finely ground into Portland cement. The burning of limestone in the cement-making process liberates carbon dioxide gas (formula CO 2). Limestone is used in the manufacture of three kinds of lime that have a wide range of uses.

We would see the sandstone shift to the left as the water gets deeper and floods the shore. The deepening water will lead an overall shift in the facies to the left, such that the limestone will progressively be deposited on top of the existing shale rock and the shale facies will be deposited on top of the existing sandstone rock.
