UCLA Meteorite Collection & Gallery
United States
Приєднався 11 вер 2020
The UCLA Collection of Meteorites is the largest on the West Coast and contains over 2500 samples from about 1500 different meteorites. It is the fifth largest collection of meteorites in the United States and the second largest housed at a university.
Our collection includes the main masses of about 40 meteorites and the type specimens of more than 300 meteorites collected from hot deserts; 60 of these are iron meteorites. Eighty of these meteorite type specimens are from the state of California. These were collected by local citizens during the past few decades, mainly from the playas (dry lakes) scattered around the Mojave Desert.
Our Meteorite Gallery, located in room 3697 of the Geology Building, opened in January 2014. The Gallery is open to the public weekdays from 9 am to 4 pm and on Sundays from 1 to 4 pm when it is staffed with volunteer docents. Admission is always free. *The UCLA Meteorite Gallery is temporarily closed due to COVID-19.

Lunar meteorites: Finally, a few anorthosites
UCLA Meteorite Gallery Lecture Series: December 2022
Title: Lunar meteorites: Finally, a few anorthosites
Lecturer: Dr. Paul Warren; UCLA
By some estimates, most of the Moon’s outsized crust consists of anorthosite, an igneous rock with more than 90% of the calcium-aluminum silicate mineral plagioclase. Plagioclase has an unusually low density, and the lunar crust is believed to have formed in a unique way by buoyant flotation of plagioclase over a global magma ocean. Some authors have even claimed the lunar-crustal plagioclase abundance is generally greater than 98%. Yet only within the past year were the first three anorthosite lunar meteorites discovered. I will discuss these new anorthosite meteorites and some other aspects of lunar rock studies that constrain the magma ocean hypothesis.

Hello, my dear friend, I am from Iran, my friends and I have collected many meteorites in Iran, a very large number, but there is no one to buy from us, we have a meteorite that I just caught myself, but unfortunately, there is no one to use these meteorites, if you can Open a branch in Iran, I promise you that on the same day, I will bring more than 100 to you. Now let someone come inside Iran to buy. I hope someone can help us. I like your good program.
Hi Mr Allan. 3 years ago I sent you some pictures of my rocks. I was new, naive and innocent to this game. I didn't know the elements to look for. I didn't know scientific terminology of meteorite. I got excited with what I saw under the lens of my cheap tiny magnifier. So I called and called scientists, geologists including you. All those calls was all dead end. I think discrimination and racism played a big role to all the denials. The rocks is full of chondrules, chondrites, widmanstatten pattern, mixed metals, fusion crust, pyroxene, long needles nickels and a lot more. Why did you said that the rocks are basically trash? Since I am now so determined that the rocks are meteorite. Looking for geologists to tell me it's meteorite or meteor wrong is a thing in the past with regards to this rocks. What I'm looking for now is classification and extensive testing. I will find that lab wherever on earth.
The atheist statement was very poor form! I find scientists that believe in a god bizarre, especially when they work with evidence and facts and there is NO evidence for any of the thousands of gods people have made up in their heads.
Pelletie meteorite for sell 5kg .

A very information rich presentation. Strong evidence for the multiple heating that lightning can cause. Great presentation.
Do you think you don’t have any or many because they probably look so Earth like? And are likely turned away or people are unsure about sending them in for testing? Also, is there common twinning in the more “pristine” crystals
Thank you for sharing these videos!!

I'm in your slow learner group. I need to have this replayed in slow motion a couple of times. Nonetheless, the subject matter is fascinating, and I enjoyed the lecture and the way you presented it. Thank you.🤩🌟🌠✴
Very helpful and educational great efforts my brother✨
Excellent video! Thank you for sharing this! I’ve watched it several times, and learn every time I do! I’d like to see a video for each type category! What exactly makes an angrite different from lodranite etc… I’d like to go back to school, but it’s so expensive, and I appreciate the free education! Please keep making these videos!
I have what I believe is the first lunar meteorite found outside a desert. I found it in north east England about ten years ago and I would say its a lunar regolith breccia. Its just under 2kg, about the size of a grapefruit and is teardrop shaped, and the shape makes me think its the one we saw when stargazing when young that fell straight down and not across the sky. The glass I collect from it is amazing and after a decade I know that these glass and agglutinates couldn't be made on Earth, and the rock is still deteriorating even though its been indoors for a decade, so couldnt be a native British rock, and a geologist confirmed its not from the UK. If I never found it then it would just crumble and never be found. Its mostly glass and fragments of material with larger light coloured chunks in a dark matrix, and apart from shape its identicl to a couple of NWA lunar regolith breccias. I will remove a piece for UCLA to test and keep for your collection if you like. That and a piece I will remive for the natural history museum will be the only pieces available because I want to keep its shape and the memory of my late friend stargazing cant be bought, so if some lunar meteorites can be worth ten thousand dollar a gram then change that to £££s and maybe it could be bought.
My lunar meteorite is like the one shown at about 20 mins except the interior matrix is dark. It's probably one of the best looking meteorites ever, and definitely the best looking lunar meteorite by shape.
I have what I believe the first Lunar meteorite found outside of a desert, and better, I believe I seen it arrive, and better again, it's the only time I've seen a meteorite fall straight down. Me and my friend were stargazing when teen-agers and a light appeared and got bigger and brighter and was a flame, and then went out. 30 years later on a walk at our holiday home I think I found it. I've studied it for a decade and it's mostly made of micro glass, and anything you find in lunar regolith can be found from this rock. It is still deteriorating after a decade indoors and I find amazing glass from it. Glass beads with tails, and some must have been spinning as they cooled because the tail has wrapped around. I can show sub mm grains that have been zapped 100s of times and show impacts where the rock has ejected a glass tail after being struck. I believe I may have found a new mineral that is made of microscopic spherules, but form a cube shape. I can find green, blue, red, orange, bicoloured, clear, green, black glass. The one thing that confirms it is the fact I can find agglutinates. The rock is just under 2kg, and is teardrop shaped. If I took a close up to hide the better shape of mine you couldn't choose it from a couple of other NWA meteorites that are described as lunar regolith breccias. People say these rocks are worth money but I enjoy looking at the dust that falls from it, and my friend is no longer with me and no amount of money can buy that moment we were stargazing as kids and I may never see a meteorite drop straight down again, but I will remove a piece for you want for you to test and keep. I will admit that it would look amazing in a museum just because of its shape, but it would have to be the most paid per gram ever for a Lunar meteorite. I plan to sort all the photos of the glass and other things I find and put them together.
Hello. A professional said that the diamond meteorite is heavy in weight compared to the size of the stone, and that it has small white or diamond-like grains all over it, and of course it is shiny, and that the veins of the stone are white and light up with the light inside this white stone, and the density is 3.1. That is, it is three and one to one and two tenths. Its absorption is very low, about 1%, and it does not absorb well. A color that is hard to express.. you can see the photo. Some friends have said that the meteorite is diamond and possibly Martian. I am a seller. Thankful Hello.

If a pallasite is metal with crystal, what would a Meteorite be called if it had stone swapped for the metal, so still had big olivine crystals but in a stone matrix, or has one not been found?
Very interesting lecture. Thank you professor.
I watched it twice in a row.
edit: three times
I have more meteorite +100kg
I think, i have pallasite.
Why was the New England Meteorite Lab result for my rocks was not a meteorite when it contents white metal grains and colored metal grains. It contents a lot of metals and ruby gemstones. Of course I sent them 2 tiny rocks without grains in it because it is in their instructions to send a sample as little as a marble. I've watched a lot of earth rocks videos, but I don't see a rock like mine. In fact some of the white metal grains have widmanstatten pattern.
What an awesome video!! I have either learned new stuff or got enlightening on the other areas that I knew!! Thank you so much!!
Hello, Paul Just wondering, is there good evidence for the un-melted lunar core shown in the "cartoon" lunar cross sections? It would seem to be gravitationally unstable, as it became surrounded by denser melt including possible nickel-iron, and likely not yet tidally locked.
Alan is a savage with those questions and replies!! 😂 great video, thank you for sharing these!!

I like this video 😍 Thanks you 💕 Great 👍 meteorite
Thank you that was very interesting. I am presently putting together evidence showing all the major stone circular monuments circa 3000 BC in the UK (including Stonehenge) are there because of a super massive bolide event. Main elements in the construction of these monuments give guidance to the same point in the sky. With the pattern of arrangement replicating what was seen viewed from above and so acknowledging to the sky/God the event. The circular ditches and embankments representing the subsequent shock wave. The 63 people ( equally men and women and some children) buried in Stonehenge at the start of construction, the victims from the blast wave possibly killed by rock avalanches close the the event. Though this does go against the present idea that all this effort was born from Stone Age man’s paranoia that if they didn’t do anything the Sun will stop rising 🤔?
Thanks Alan, Enjoyed your lecturer Ken

My meteorite that I saw fall from the sky is almost completely non magnetic… took me almost 10 years to find it. I’d never sell it. Cute meteorites. ua-cam.com/users/shortsXKwUkGqiltA?feature=share
