Walther's Law Of Sedimentary Facies

Walther's Law: The distribution of environments represented by rocks in a vertical stratigraphic column is related to the distribution of those environments laterally.

Time in Sedimentary Rocks…Estimated might be younger…Y??


In this video, instructor discuss the idea that older layers underlie younger layers. However, the age of individual grains can be significantly older than the age of the layer they were deposited in because the grains have to exist before they are deposited. In the special case of layers of volcanic ash, the ages of crystals in the ash might be only slightly older than the age of the layer they are in, which provides excellent opportunities for measuring the absolute ages of sediments.


Lecture on age of Sediments. Individual Sediments may be older than time of deoposition

Deltaic sedimentation experiment in Lab

This video is a portion of a deltaic sedimentation experiment done at UNLV. It was done as part of Dr. Andrew Hanson's Sed/Strat class and shows different phases of deltaic sedimentation, erosion, and sequence stratigraphy. The plans for this flume tank are at The plans come from Dr. Thomas Hickson (University of St. Thomas) and Karen Campbell (National Center for Earth Surface Dynamics)

Relationships of sedimentary rocks, sequence stratigraphy and terminology

Nomenclature of relationships of sedimentary rocks, sequence stratigraphy and terminology, eustatic cycles, definitions of formation and its multiples, geochronologic and chronostratigraphic compared, stage definition, GSSP (Golden spike) main fossil groups for biostratigraphy


Law of superposition, formations are lithologic, stages basically biostratigraphic, but tied to paleomagnetic reversals, Milankovich cycles, eustatic cycles and sequence stratigraphy. For correlation fossils are best, but well logs aid. Report presentation.
