Fascinating data & presentation. Have you considered impact ejecta & a plasma, magnetohydrodynamic process related specifically to Impact-phase comets? Planetary Collision Dynamics would seem to be a naturally, reoccurring fact for producing geomorphological anomalies found in Earth's crust? Comets atomize their chemical-elements & slam into Earth at Mach >30. 🤔🖖🏽♻
11:44 Why isn't the Oceanic Plateau derived Siletz Terrane (also studied as derived from the YHS and with @12 times the volume of the CFB's) included in blue in this chart?
I’m guessing because it’s gone now so they would have had to include other mounts that are no longer there? We also don’t know where to put Siletzia latitude wise or how far offshore it might have been and there’s a few different models. One thing I noticed about the Baja BC thing is when they assess the faults for offset in a couple of the lectures, they obviously go by whether it’s sinistral or dextral by the direction of the shear, but when an area reverses course the shear will change directions but not necessarily be obvious that it sheared in the other direction originally. I learned about this shear reversal in a fairly new gold deposition study and maybe this study hasn’t been picked up yet by Baja BC people. Idk how they’d go about testing which strike slips have reversed their shear direction, but it seems like a possible solution to not being able to find the fault or lacking enough offset, it might look dextral now and have been accidentally disqualified without a closer look.
_" ... we don't form plagioclase crystals hydrothermally ..."_ Is that definitely true? I'm able to find reference to _small_ plagioclase crystals in hydrothermal veins. If they have a magmatic origin, why aren't they uniformly distributed throughout the flow? What would concentrate them?
I found one the size of my thumb in the cinders that a friend is now faceting. It appears to me the crystals were solidified while the magma was still liquid.
There is a small cinder cone called Crater Butte at a Y in the road between DuBois & Kilgore Idaho. It is full of sunstones, insitu. This volcanics is the Yellowstone Hotspot, hmmmmm, connection to CRBs???

Lower density.
