Uniformitarianism, Horizontality and Time Posted by: sumnerd
Video duration: 218 seconds Global video hits: 1740 Sedimentology Concepts #1 I briefly describe the principle of uniformitarianism, the principle of original horizontality, and the fact that younger beds overly older beds (surprise, surprise!). These concepts are key ideas for my course in Sedimentology and Stratigraphy. This video is my first and is intended as a study aid. Related: geology, sediment, sedimentology, stratigraphy |

Meandering Rivers Posted by: sumnerd
Video duration: 377 seconds Global video hits: 1646 Sedimentology Concepts #9 Meandering rivers have distinctive migration patterns and deposit distinctive sediments, which I describe here. Related: geology, sediment, sedimentology, stratigraphy |

Turbidites Posted by: sumnerd
Video duration: 361 seconds Global video hits: 1714 Sedimentology Concepts #7 Submarine debris flows create turbidity currents, which deposit turbidites. Here, I describe the processes leading to turbidite deposition and the facies deposited Related: geology, sediment, sedimentology, stratigraphy |

Walther's Law Posted by: sumnerd
Video duration: 290 seconds Global video hits: 1870 Sedimentology Concepts #2 Walther's Law: The distribution of environments represented by rocks in a vertical stratigraphic column is related to the distribution of those environments laterally.

Sedimentary Facies Posted by: sumnerd
Video duration: 272 seconds Global video hits: 1687 Sedimentology Concepts #6 Sedimentary facies are groupings of rocks used to highlight the most important features for a research question. Here, I describe the concept of facies and give a couple of examples. Related: geology, sediment, sedimentology, stratigraphy |

Sediment Transport Posted by: sumnerd
Video duration: 235 seconds Global video hits: 1983 Sedimentology Concepts #4 Sediment is transported as bedload by rolling and saltating. In this video, I review the connections between the boundary layer and sediment transport, including the Bernouli Effect. Related: geology, sediment, sedimentology, stratigraphy |

Waves and Storms Posted by: sumnerd
Video duration: 329 seconds Global video hits: 699 Sedimentology Concepts #10 Wave and storms produce distinctive structures in sedimentary rocks, and I describe them here. Related: geology, sediment, sedimentology, stratigraphy |

Chrono and Lithostratigraphy Posted by: sumnerd
Video duration: 370 seconds Global video hits: 685 Sedimentology Concepts #8 Correlating rocks that were deposited at the same time (chronostratigraphy) differs from correlations of rock type (lithostratigraphy). Here, I describe the differences and provide an example Related: geology, sediment, sedimentology, stratigraphy |

Deltas Posted by: sumnerd
Video duration: 278 seconds Global video hits: 1101 Sedimentology Concepts #12 Rivers bring sediment into standing water, e.g. lakes or the ocean. Deltas form when there is enough sediment that land builds out into the water. Here's a summary. Related: geology, sediment, sedimentology, stratigraphy |

Tidal Processes Posted by: sumnerd
Video duration: 295 seconds Global video hits: 707 Sedimentology Concepts #11 Tides produce distinctive sedimentary structures due to systematic changes in flow direction and speed. I describe the basics here. Related: geology, sediment, sedimentology, stratigraphy |

Ripple Cross Lamination Posted by: sumnerd
Video duration: 271 seconds Global video hits: 1476 Sedimentology Concepts #5 Stratification is produced by bedforms and can be used to interpret flow conditions. In this video, I summarize where deposition and erosion occur on a ripple or dune, how that relates to the boundary layer, and the cross stratification produced Related: geology, sediment, sedimentology, stratigraphy |
