Aug 23, 2020 · Stratigraphy and Time. Stratigraphy is the study of sedimentary rocks in space and time. It is the basis of interpreting what happened in the past. We use facies to interpret depositional environments from the rocks. Changes in facies both vertically and horizontally allow us to interpret changes in ancient landscapes and processes.

Both types of maps show the thickness between two mapped surfaces, but differ in how the thickness is measured. Isochore maps measure the thickness from a point on the upper surface straight down to the corresponding point on the lower surface. Isopach maps display the stratigraphic thickness between an upper and lower horizon.Checking out mall maps online before heading out can help you plan out your trip.

A sequence stratigraphic surface is a type of stratigraphic contact that serves, at least in part, as a systems tract boundary ( Catuneanu et al., 2011 ). As systems tract boundaries, sequence stratigraphic surfaces mark changes in stratal stacking pattern between the units below and above the contact ( Fig. 11 ).
