If the igneous layer was intrusive wouldn’t there be noticeable change in the adjacent sedimentary beds? I would expect to see some quartzite character in this felsic layers. Also, in general I’d expect the igneous intrusive layer to be more erosion resistant than sandstone. The lack of metamorphism, and the less resistant nature of the andesite layer lead me to guess it may have been depositional - but only if you found clast-like morphology. Another great video, thank you!
Great video! I spent a lot of time at Refugio as a kid in the 70's (camping with my family) and it is great to see you looking at the geology in the area. I appreciate you sharing your observations and interpretations. I suspect you are on the mark with the idea of the sill intruding the strata. I am curious as to what the sill looks like higher up on the outcrop. Thanks for another interesting episode!
Thank you so much for providing this video! I believe that the tar/oil is after the fact. There has always been a bad tar problem at the beach, but due to a growing number of oil spills in the area, it has gotten really bad last couple years. I always bring a bottle of vaseline/baby oil with me to the area’s beaches.
So cool. There's probably someone in the geology dept at UC Santa Barbara that knows the story here. Or if not, they're probably really interested in your finding.
❤ this so much! Spent hours and days of my youth on Refugio and Gaviota Beach(es). Love Santa Barbara County so much. Have you been to the Sulpher Pools?
Tar possibly from huge oil spill in 1969, those cracks are at high tide line and the sharp nooks hold the oil/tar in place? Also, tar glops leak up from the seafloor and get washed up. Most gets cleared from the beach and deposited to new car floor mats using the bottom of young kids feet as the transplant mechanism.
I thought so as well. I was wrong. The tar pits along the coast here have been resources to the indigenous Chumash people. Carpentaria was named by the Spanish to signify the canoe-building yards and basket weaving works. Both endeavors required tar for waterproofing. The evidence is on display in the Santa Barbara Natural History Museum.
@@him9lton I forgot about the tarpits. I used to live in HB (jeez.. 50yrs ago.. dang) and there were places near my home where tar seeped up in open fields. Also I've scubadove off the cliffs about 1/4 mile out there's a rock reef and gas bubbles rise from there and the occasional tar blob too. Nearest place we have as a museum is San Juan Capistrano Mission... Where in grade school we were taught the natives were barely ekeing out a living, and would have died out if not for us settling here. In our ignorance, plowing Orange County under to grow crops proved to be a mis-management of the land. Turns out building single family homes attracts food to the area, without the eyesore of open lands... sigh
@@him9lton yup, same thing is happening in San Pedro, by the beach, you can see the tar in greater concentration oozing out of the rocks. and the La Brea tar pits are not that far away too.
Did you see all the concretions in the sandstone and along the beach? They have mammal bones and sharks teeth in them. Also lots of petrified whale bone on the beach.
So what is the real story of this andesite flowing over this portion of sumberged metamorphic (saline) bed of siltation ? Santa Barbara is a long, long, long ways from Shasta, Lassen, Tahoe, Yosemite, Long Valley cauldera, ... and maybe part of the Grapevine basalt triangle holding back the LA-Baja fault peninsula from moving northward ?
There was several areas in Southern California that have volcanic intrusions all dated during the Miocene during the clockwise rotation extension (Transverse Range movement and associated extension). I've seen a dacite intrusion in Oceanside and andesite intrusion in Laguna Beach at Crystal Cove State Park. This sill looks like it may be associated with that same extensional story. None of those areas have an associated volcano; these intrusions were happening in extensional fractures deep down and only now, due to uplift and erosion, are being exhumed for our viewing pleasure.
To my geologically untrained eye, it looks like an awfully long horizontal intrusion. What’s the possibility that 😮 this is basalt or something extrusive when this layer was being laid down?
@@johnbollenbacher6715 Wrong kind of lava. For that kind of flow you need ultra mafic lava with low viscosity. It doesn't form those kinds of minerals, but that was a good thought for how it might have gotten there. An intrusive "sill" is more likely.
@@huntermcclovio4517 I didn't say anything funny I stated the truth I have an eyewitness account to the flood you are just deceived by mainstream geology all the features of the Earths geology can be explained as a result of the flood better than uniformitarianism
@@oscarmedina1303 nothing mythological about the Bible it's all eyewitness accounts and historical.

Thank you. I live down the tracks in Goleta. I’m going to Refugio and check it out.
Another fantastic geology session Todd. Awesome site. What a story the layers are trying to tell.
Thanks Rick!
Oh dang, look at all those super interesting rocks! Gorgeous formation. And intrusive volcanics?!! Really fun puzzle. Thanks!
Oh hey im at Refugio State Beach right now! This geology is awesome to know and observe at the same time, nice video!
Oh wow! What a coincidence! Enjoy and thank you.
So interesting. Thank you for the upload. You have a gift for presentation. Cheers from England.
Thank you kindly.

This is awesome, similar geology at Shell Beach, CA

Geo man ... always finding some anomalous CA lands ... kudos
I used to spend summers at Refugio Beach, mid 80's, early 90's, there were tar balls everywhere, snack bar sold alcohol wipes for your feet.

Super cool
I believe that there is a fault line under Refugio and continues into the Santa Ynez Valley north of the beach
Great, interesting.

This is what the National Park Service explains: www.nps.gov/chis/learn/nature/geologicformations.htm

Did someone say “Monterey Formation” 👀

Lava leaked up at the beach?
Or it flowed out over the beach.

"Refuheeo"
Beautiful evidence of the flood recorded in Genesis
bwahahahahahahahahaha 🤣😂😅 that was funny!! you just made my day!!
