So the full sequence of events is as follows: Layer C formed. Layer B formed. Layer A formed. When layers A-B-C were present, intrusion D formed. Intrusion D cut through layers A-C. Fault E formed, shifting rocks A through C and intrusion D. Weathering and erosion occurred, forming a layer of soil on top of layer A.Geologists are able to 'read' the rock layers using relative and absolute dating techniques. Relative dating arranges geological events - and the rocks they leave behind - in a sequence. The method of reading the order is called stratigraphy (layers of rock are called strata).Dolomitic Marble is a coarse-grained, non-foliated metamorphic rock composed primarily of dolomite. It is usually white or off-white, but if impurities are present it may also contain colors like pink, gray, blue, or green. Dolomitic Marble is formed from the low-grade metamorphism of dolomite.
