Those Remarkable Floating Rock Formations | Morris, HM. 1983.
Impact 119:i-iv. CELD ID 3065Abstract The most basic rule of stratigraphy is that sedimentary rock formations on the bottom are older than those on the top. Sedimentary rocks are formed by the erosion, transportation, and deposition of sediments, and nothing could be more obvious than the fact that deposits on top were laid down after the sediments below them. However, this common-sense rule often seems not to work.
