Compare and contrast lithostratigraphic, biostratigraphic, time-stratigraphic, and time units
Discuss time-transgressive lithostratigraphic units. Discuss correlation of different types of
units. What will be an ideal response?
The student should discuss that lithostratigraphic units are described based on rock-type only.
Biostratigraphic units are based on fossils contained within the units. Time-stratigraphic units
are sequences of rocks that were deposited during a specific time period. Time units represent a
period of time very much like seconds, minutes, and hours. Correlation is the recognition that
two units are lithologically, biologically, or temporally related based on rock-type, fossils, or age
ranges
