Sequence stratigraphy 3
This 125-foot core drilled in the Po Plain, Italy, was extracted from the subsurface and partitioned into 3-foot segments. The top of the first core segment, left, represents the present-day plain surface, and deeper depths are shown to the right. In a study published online Friday in Geology, researchers dated mollusk shells extracted from the sediment to conduct the first direct chronological test of sequence stratigraphy, a powerful tool for exploring Earth’s natural resources.
