It implies that strata in the “doughnut hole” are younger than the chalk, and strata outside the ring’s periphery are therefore older than the chalk. This map is an important milestone, but it’s not what most geologists would instantly recognize as a geologic map because it emphasizes just one unit, excluding all others, and because it uses only one color.
Most of the exposed layered rocks are sedimentary rocks. Geologists tend to use the term 'rock strata' in a generic sense when referring to many rock layers that appear over large areas. The singular form stratum, which is a Latin word that means 'spread The geologic time scale (GTS) is a system of chronological dating that classifies geological strata (stratigraphy) in time.It is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events in geologic history. In a similar way, fossil shrinkage cracks are found throughout the geologic record in strata that have been deposited on land (as opposed to those deposited in lakes or in the sea). They are very common features of the geologic record.

Stratum, plural Strata, sedimentary rock layer bounded by two stratification planes, the latter being produced by visible changes in the grain size, texture, or other diagnostic features of the rocks above and below the plane. A stratum that is less than one centimetre (0.4 inch) in thickness is termed a lamina, whereas one greater than this thickness is a bed.
