Southern California Geology | Mafic Enclaves

Featuring a swarm of fine-grained, mafic enlaves, some ellipsoidal, appearing to swim through the surrounding biotite-hornblende monzogranite pluton emplaced some 103 million years ago within the Western Transition Zone of the Peninsular Ranges here in Southern California.

Todd - excellent work. Drone shots pushing in to the outcrops especially effective. I don't think I've seen drone used like that. Congrats.

I love your enthusiasm for geology! Geology is one of the most fascinating subjects because the planet is so dynamic. It's constantly changing in some way!!

Man…I recently stumbled onto this cache of geology videos. Wow! So good! Nice mix of the available tech (drone shots!) and old school narrative creation! Lots of learning goin on here! Thanks!!

Todd, I love your videos! There's nothing I love more than someone that is passionate about a subject and excels in sharing their knowledge about it. California is rich in geology and I can't thank you enough for these informative videos. I taught 4th and 5th grade science and I loved geology and it was so thrilling to see students actually get excited about the rocks and mountains all around them here in southern California. Keep it up!

The flow pattern really gives the sense of current and activity in the chamber. That is a first for me. I know it has to happen but I have never seen it so plainly that you can't miss it. Thanks Todd.

I visited this site in 1978 for a Spring Field geology class while an undergrad at UC Riverside with Dr. Doug Morton, Dr. Peter Sadler and Dr. Lewis Cohen leading the class. Nice having a drone to climb up the rock face…didn’t have those in the ‘70’s. RIP Dr. Doug Morton who did a lot of pioneering work on the Southern California Batholith.

Thank you for explaining our property spectacular boulder field adjacent to the morro hill plug oceanside. Was fascinated why we had different rock. Thank you.

Finally Bro! Another video. Please keep them coming. Great content.

I remember climbing that slab ten years ago and wondering about the geologic forces that were in play. Thanks for making a video about this fascinating area!

[PhastRocket]

I am glad I found your channel. I drove through the area once in a while and often wondered what made up these rocky outcrops in the Riverside County

Some chunks look like cookie dough, some pancakes.
Another tasty episode, G.S. 👍

Very interesting video Todd. Loved your commentary about the mixing of magma and the drone shot up the frozen plume was fascinating. Thanks for including the longitude and latitude for those of us that would like to take a personal look. I'm planning a visit.

Geology Rocks shirt. Looks like Mt. Hood. Can't wait to go to some of your sites. Thanks

[drbobinski]

Thanks Todd, as always love the info, your amazing passion and the unique reggae. Just got me a chunk of Volcanic plug from the top of Bishop peak in SLO. Great hike and killer story for a future episode.

Great looking rocks with an interesting pass. It fun seeing rocks other than ancient sea floor as much of NY PA and OH are made up of. Really enjoy your videos!! Thanks

Super cool. Wished I had known about this previously. Would have gone and checked it out. Of course we had our own wonders in Poway/Ramona area.

[dsfavs]

love all your videos and good taste in music

[markvanleeuwen]

Lots of mafic enclaves in sandiego too. posted on nz a while ago. Looks like fish. Cool. Nice work.

Love this stuff...wish there were more.
