  • OT---Geologic Timeline

    Some of you might remember my interest in geology. I recently came across a Nick Zentner video on the timeline in the floor where he works, Discovery Hall, Central Washington University. I so wanted one I did one in chalk on my street and made a video; https://www.youtube.com/watch?v=9EfY8YT1b-8

    Enjoy!

    Well...I wasn't really feeling insignificant till I watched your video, Gene!

    Probably beyond the length of any video you'd want to make, and likely a difficult task to summarize in single sentences, but I'd be curious to know what differentiates each period, one from the next...ie: [this quality] defines the triassic period, then [this] happened, ushering in the jurasssic period, etc. Looks like there are 22 periods, according to Wikipedia--I'm sure they aren't just random divisions of the eras.

      I think most of them were due to a change in lifeforms and extinction events. The forming and breaking up of large land masses such as Pangea's breakup 251My and the forming of the Atlantic rift zone. I mean the Appalachian Mtn were formed when 480My ago Pangea was formed causing them to be as tall as the Rockies at one point. The wiki page on them is interesting;

      You want to feel insignificant; I worked out that if a half inch was a million years, the Big Bang was 13.78 Billion years ago that would be 10,874.3687 MILES!

        Very cool Gene. I get the feeling you're looking for the answer to life, the universe and everything...

        So your presentation made me want to see what it looks like going thru all time. Like your curiosity led you to calculate. 1/2" = 1 million years what would that distance be for all time? Here's a video that illustrates that. Strange how these concepts don't make me feel small/insignificant. I found that standing at Pueblo Alto in the high desert sage with no other soul around.

          Badvibes, not really looking for those life answers, just an overall interest in sciences. I wish I had a mind for math, it's just too hard. I have learned so much from the internet and youtube about genomes, physics, geology, astronomy(which the James Webb will change), history of migrations and conquest, etc

          I guess I saw the version 1 of that video, it's very kool, Surprised they didn't go back to the CWB(Cosmic Wave Background) or maybe that blueish stuff was their version.

                  Very cool Gene. Hard to wrap your mind around what that type of time really means. It's like trying to define the volume of what the universe fits in and what contains it.

                    The geologic time scale is based on origins and extinctions of different life forms, primarily marine, with the eras, periods, and epochs defined long before radioisotopic dating was invented. Key early players were William "Strata" Smith for the science of stratigraphy, and James Hutton for process ('The result, therefore, of our present enquiry is, that we find no vestige of a beginning, - no prospect of an end. ' Hutton 1788). Even after >200 years, the primary divisions remain largely unchanged, but absolute dating techniques continue to refine the ages of the global extinction events (excellent example is the Cretaceous–Paleogene (K–Pg) boundary) as well as the origin of new groups. Dating has proved key to figuring out the Precambrian, the stretch form ~541 million years back to the origin of Earth (~4.54 billion years ago). The history of the science of geology is as fascinating as the data themselves!

                      STRATIGRAPHY, PALEONTOLOGY, AND GEOLOGY OF THE CENTRAL SANTA CRUZ MOUNTAINS, CALIFORNIA COAST.RANGES By Joseph C. Clark

                      "Southwest of the San Andreas fault and northeast of the San Gregorio fault in Santa Cruz and San Mateo Counties is one of the most complete Tertiary rock sections in the California Coast Ranges. Overlying a Salinian basement complex of granitic and older ,metasedimentary rocks is a succession of arkosic sandstone and mudstone units, Ranging in age from Paleocene to Pliocene and having a composite thickness of as much as 7,390 m."

                        Good thing I made the video, it rained yesterday and now can hardly see evidence of it.

                          So is this the event that divides the Holocene from the Geneocene?
