In physics and materials science, the Curie temperature (TC), or Curie point, is the temperature above which certain materials lose their permanent magnetic properties, which can (in most cases) be replaced by induced magnetism. The Curie temperature is named after Pierre Curie, who showed that magnetism was lost at a critical temperature.
So impact can cause a change of magnetic order. Impact is a physics so powerful it alters matter at an atomic level.

Large Shock Circle from Eldorado National Forest in NE part of state.
Catalina Island, California, USA - These off shore impact structures keep turning up impactites. Only problem is geologist don't know what an impactite looks like.
Here is an article about the structures.

Shown below is a specimen presented to a major geology forum without any recognition of the above article or what this rock is.
Living in a crater as I do, you see a lot of rocks like this. It is "meteor hits sand." A shock metamorphic, with iron, olivine and little iron specs. It also still has some of it's particle construction visible from the "shock particle storm."
Yosemite - People don't think of mountains are crater walls but I do. The projection is an impact matrix. Behind that is a converging wave form. In front is impact particle storm "constellationing."

Strata above was found by Jessica Johnson at Kern River Kernville, CA. It is an impact sequence with drying mosaic edge. It has fast formed concretions, the small shock particle storm matrix and baby blue look which could be an impact metamorphic NaCu2Si3O8(OH)
Bakersfield, CA Impact Crater - Icicle tube wave with shock olivine in quartz. Specimen collected by Josie Marie.

the nevada basin impact that made the rocky mountains as a crater wall. most impacts are 45 degrees but this one was a lower angle from the southeast. earthquakes are the tectonics resolving the broken up material. the high number and magnitude of earthquakes is in relation to how recent the impact was and how much damage it did.
Mono Lake Nevada. Can you have impacts into mountains? Yes. These specimens described asThese are original sketches of thinolite made by Edward S. Dana from his book from 1884: Crystallographic Study of the Thinolite of Lake Lahontan.[
Shock made polymorphs. Mono lake also has

Dendritic tufa - branching structures that look similar to small shrubs Fractal Dendrite structures are a fast made energy based crystal form.
The up blast is it volcanic? Is that mountain in the background an impact crater wall?
Tubular flow from an earth crust breaking impact. It is part of a wave phenomena which has a period selecting the tube size. Shaina Kinn is in Mammoth Lakes, California.
Heart Rock, San Bernardino National forest - This is a branching fractal tube wave phenomena. See on the left rock face the three tube wave pattern. Next it jumps to the two and then one. It is a harmonic decay. Fractal tree branching that requires a quanta packet decay. This is shock made plasma mega clast with cobalt. Surface patterns illustrate granular particle constellationing.
Discrete tube waves are unlikely. As seen above with the crater tube wave bifurcation tube waves are more likely to split. While this is certainly a shock made strata, holes are common to many areas of the impact relics the action of water here cannot be ignored. Alas cavitation can also occur with plasma projectiles even this large.

Missy Willett Carter Duncan Harold Payne is correct. Are no consistent flow directions as with a meteorite. Is too complex for slag or volcanic orogeny. Is from a large earth impact. It has caught impact spheres and was very hot indicating it is a close in relic.

Not sure what this is? Anyone know? Southern California.
Up striations from a very big Earth Impact. Not as well formed as column basalt which is an upward moving sphere splash stream but the same up splash effect. Sept. 11, 2023.

Photographer spent the weekend photographing El Capitan in Yosemite from various angles. Here's the Andromeda Galaxy rising as El Cap's face illuminates the crescent moon [OC] [4000x6000]
BUT...
THE PHOTOGRAPHER managed to capture not only Andromeda, but also Triangulum (a constellation in the northern sky, the 78th largest, whose three brightest stars form an elongated triangle) - a galaxy in the lower right corner
and the red giant Mirach between them AND Cassiopeia in the upper left corner!

Impact spheres made from the limestone strata in the initial of final phase of the impact. As a provenance issue these spheres tend to confirm the picture before was impact. Sept. 11, 2023.

I can't even imagine whats in the center of these — in Parkfield, California.

Tafoni weathering. Wish I had the details handy to explain it. When I first saw it at Bean Hollow State Beach south of Santa Cruz, California I was fascinated and mystified, so I did some research. Google tafoni and learn about it.

Any idea what this might be ? I found several near each other , in the Mojave desert of SoCal. Very hard, round, shapes

Impact mega clast/half impact sphere, Joshaua Tree National Park in Southern California. The internal lines are a resonance banding along with the bounce back agate forms along the crust. Needless the say we are looking for a large earth impact. Dec. 28, 2023.
Impact spheres and impact shatter coning at Joshaua Tree National Park in Southern California. Dec. 28, 2023.
Geology anomaly map from Chegg Products and Services. The Nevada Basin Crater is the most likely cause of the impact specimens shown above. But the offshore impact is also a good contender. So which came first? Is hard to tell as they don't seem to have overlap. While plate tectonics is used to explain the California geology it is impact tectonics that made it. The earth is still resolving these major impact made crust breaks (Crusta Confractus) Dec. 28, 2023.
Impact geometrics a resonate made form. Dec. 28, 2023.
Impact breccia, rare type - Shock/electrical veins running through the broken clast with ball effect, very rare. The ball effect is the same as ball lightning when the fractal drops below trunk strength and switches to ball. It can switch back as a cusp quanta phenomena. Jan. 15, 2024.

Impact breccia in high heat mosaic matrix from Lake Tahoe Impact "Structure." The later the impact structure the more likely it is to contain round cobbles. Impact structures versus craters - Simple craters like Well's Creek in Tennessee or the Barringer Crater in Arizona can make a roundish bowl crater no matter what the angle of impact it is thought. True if arriving on a flat surface otherwise it too will make a structure. The heat required to melt limestone is around 2,500 degrees F. The pressure required to melt limestone is 80 Bar or .008 GPa (Giga Pascals). Why not Raft/Plate Tectonics? This is a fast form with exposed surface mosaic not a compression form. View - Tree fell and roots pulled up the undersurface so we are looking at a reverse surface with the high melt back and the cooler cobbles foreword. The theory view - Even the Barringer Crater is somewhat square and not a perfect bowl. The theory of impactites is stuck in the Shoemaker era. From a forensic physics standpoint everything found in a crater would be assumed to be an impactite associated with the impact and disambiguated from there. So, let's take a look at a Barringer Crater Boulder. As you can see the surface mosaic is much less as it is a smaller impact. It also has a thinner depth. Jan. 23, 2023.

What’s this about?
South Tahoe area
Thanks
Crater offset left - See the complex surface structure is likely the crater central impact. The Lake Tahoe Impact Structure has a complex central impact point. This is another impact from the east, counter to the Earth's rotation which makes the impact more kinetic as the Earth is moving at 18 miles per second and most of these later smaller impacts are at "capture" speed of around 15 miles per second.

I am collecting for over 50 years and never came across anything like this, not even close. Nobody? Found in Joshua Tree California
Expansion shard from impact. The matrix appears to have been once limestone now shock altered to dolomite. The circular nature is the expansion bubble fast form often these are spheres. The surface experienced another part of the blast wave containing copper. The smooth inside is due to the plasma nature of the expansion gasses. You can see the LA Basin Impact and the shadow remnant of another impact on the attached magnetic map. Your location could have been from either impact.
Expansion bubble forms and high velocity elongation - The spheroid this shard came from appears to be more oblate. These type forms were shot out at very high velocities up to 50 miles per second. As they are plastic liquid forms this elongates them to tear drop shapes or even tubular. Feb. 17, 2024.

Ellwood Beach, Goleta. The storms have washed a lot of the sand off our local beaches. This is the striated bedrock underneath.
Topo craters of California. Raft/Plate tectonics is a shadow theory like Plato's cave. The real cause of the earthquakes is the rubble shifting and seating itself resolving the earth curst stress from these impact disturbances. A crater can break up the Earth's crust as far down as it is wide radially. March 22, 2024.
Oblate impact sphere with high heat mosaic cracking. In the background you can see another impactite with a flash melt top. This is a likely large crater, and those boulders were once in the impact strata and ejected out. May 19, 2024.

Impact blast nodules and mosaic fingering, from the Lower California/Baja Impact. While I often see blast nodules as posted specimens, I usually only see fingering as a feature in impact strata. Why a fingering mosaic as opposed to other mosaic patterns? It has to do with the associated edge. The heat cracking comes from it and just splits inward. May 31, 2024.

So the desert out here in Imperial County, CA every couple miles you turn right into these little alcoves in every rock is different here is just a few examples of the strangeness of the rocks out here and they're nothing but they're cool I donate them to the junior high and the high school geology department and they love them
