==Development of sequence stratigraphy==

==Development of sequence stratigraphy==

In the late 1970s, [[seismic data]] was interpreted stratigraphically to define packages of strata hundreds of meters thick that were deposited between sea level cycles that lasted 0.5–5 m.y. During the 1980s, a finer resolution of stratigraphic analysis developed when outcrop and well data were applied to seismic stratigraphy.<ref name=ch21r47 /> This type of analysis, termed '''sequence stratigraphy''', defines a hierarchy of stratal units that range from thousands of meters to millimeters in thickness and that were deposited by events that range from tens of millions of years to days in duration.
