I saw that zebra rock and got excited. "Looks like my gneiss sample!" and all that implied. Then, hopes dashed--no primordial tectonics. Thank you "Mars Guy" for another stimulating Sunday morning.
As a non-geologist it's always impressive to see how many different rocks and minerals nature cooks up in her kitchen of chemistry, temperature and pressure. Geologists seems like detectives to me.
Absolutely they're detectives. First they deciphered the prehistory of the Earth and the formation of the Solar System, and now they're getting to grips with Mars. It's an incredible time to be alive.
😁 The old saying in medicine "sometimes it's a zebra," to point out the odd diagnosis. One can hear the sound of hooves but it's not always a horse... 😊
These little "gems" of unexplained findings on the surface of Mars are part of the reason for exploration. They keep our attention and curiosity moving forward. Oh for the day when humans can reach out, pick it up, analyse and find the answers they seek. Until then, thanks Mars Guy.
I'll be 68 in November. I want to be around, too! I also want to see what they find in the oceans of Europa. Just give me my smartphone in the nursing home, and I'll be happy. 😊
Until robots can construct a safe habitat, we fragile bags of meat are ill suited for the solar radiation and lack of atmosphere on Mars. I think Mars visits by humans will not happen until AI robots can build landing pads and pressurized living and working quarters before we launch.
I was born during the IGY in '58... same year the U.S. launched its first successful satellite, Explorer. I still live about 90 miles away from "The Cape" and from this vantage point, I have watched them flying humans from the Mercury program up to the Dragons now. I grew up reading Golden Age science fiction... so seeing it FINALLY beginning to become reality... is a "bucket list" goal for me also. Carry on!
Maybe Perseverance will be lucky and find another one. It is odd the One Zebra Stone is just sitting alone on the surface. Where is its Mother OutCropping? ☆☆
I live on the edge of old glacial till and I have seen rocks much like this while tilling my garden. I always assumed they were igneous or metamorphic, also very heavy. I will have a friend examine it (a geologist) and come back and repost if I find anything out.
Ireland has/had some brilliant white quartz glacial erratic stones that were revered in the past - they were centerpieces to stone circles 3000+ years ago. Some were quite big (on record, now sadly destroyed). These stones / boulders were so bright and unusual in the local area they became focal points for gathering, apparently. It seems Mars also has some erratic stones it needs to explain.
Truly fascinating. Both the zebra rock, and the investigative thought process of a martian geologist. A very insightful description to what differentiates this rock. Thx Mars Guy.
Where I live in Norway at about 62.2 N near the west coast there are quite a lot of rocks like this. I think it is a magmatic granite rock, or possibly formed in thick rhyolitic lava flows. However it can possibly be a dioritic/andesite or possibly gabbro rock depending upon the exact quantity of light vs dark constituents.
Some day a geologist from earth might be able to find that rock again and be able to answer all the questions. Thank you for sharing. Have a great day and stay safe.🙂🙂
@@stevenr8606 That was my suspicion, but, I still felt their stupidity deserved being called out... 😏 I figure if you don't, they'll think it's acceptable behavior and continue to do it. _(yes, I treat them like children because, let's face it, that's the level of maturity they exhibit 😁)_
Once again, a fascinating enigma. Metamorphic rock, if that is what the Zebra Rock was, suggests a very active geology in Mars' distant past. Once we have boots on Mars' ground, the entire geological history of the planet since its molten state will be an open book given the apparent lack of plate tectonics. A research geologist, such as yourself, Mars Guy, has to be chomping at the bit to be about it.
Good Morning, Mars Guy. You always ask interesting questions. Like how was the rock formed. You're right it is remarkable. My question would be. How did these rocks end up virtually in the middle of nowhere? The rocks are maybe similar to the rocks on earth. Another question I have. Is there a possibility That there a elements on Mars that are not on the periotic table? Great Episode. You really make people think. Have a Great Sunday, Mars Guy.
This certainly looks like a bimodal volcanic tuff. If so, the dark areas are basaltic, and the white andesitic to rhyolitic. Such tuffs can form where basalt intrudes older rock, melts a higher silica fraction out of it, and the two liquids are erupted together. This rock is very well rounded and has been transported much further than the angular basalt chunks which are so common in the area.
Good morning from Paris this week MG maybe these stones are like the mile markers we have here on Mother Earth. It’s so beautiful to drive around Mars together.
As somebody who loves to pick up cool rocks, the fact that this particular rock's exact location is known but we can never got back and look at it again makes me *so mad*.
I saw an image of this rock posted a while ago and I was waiting for your discussion about it. Very interesting! I can't think of a good pun about mean rocks at the moment.
What is hard for me to understand, why they do not go back sometimes to investigate. It is pretty clear they do not know exactly what this rock is, how it formed, etc... and the rover is there to investigate info of exactly such unknown things... but they just drive away...
As the primary directive is to look for signs of evidence of life, unfortunately the geology of how it formed, has to take a back seat. But like the Galapagos Islands, it's not going anywhere. Other explorers or robotic explorers, will eventually return to that area, I am sure.
My guesses: 1) It's unlikely that stone is unique and there's a reasonable chance of finding a similar one if they just proceed. 2) Moving the rover is always a bit dodgy, Percy has very nearly got stuck a couple of times. Perhaps back-tracking through that terrain is simply too high-risk?
They do alter course quite often. On this occasion I guess they weighed up all the options and decided that it would be better not to. If they always took a beeline to the nearest shiny thing the rover would have probably immobilized itself long ago.
The rock looks like modified lava with iron mineral like dark material in it. I have seen Dolomites and granite with similar patterns. Tahoe area granite has a similar appearance.
@@MarsGuy As kid I spend a lot of hours in a camper traveling around the US. Also had a mom that studied geology for a bit and got to go on field trips around the southwest (grew up in Tempe). Have you ever had the chance to Rome around the south side of Camel Back mt? Lots of interesting stuff was exposed while they were building homes up that side.
As Perserverance appears to gain elevation perhaps the zebra rock source outcrop will be encountered. The rock appears subangular to rounded suggesting its been extensively sandblasted by wind and/or rolled down slope some distance by intermittent flowing water. Maybe it rafted in on ice from ancient glacial melt waters. Weird.
Wow. Wouldn't it be incredible to know exactly how one unique zebra rock got to where it is, all by itself, in the middle of nowhere? Sadly, we'll never find out in our lifetime. But Mars Guy's videos are so fascinating, you can’t help but wonder., and wish.
Could it be of meteoritic origin? It's pretty odd to be so strikingly different from anything else we've seen there.. If anything's worth of turning the rover back for a closer look, it's oddities like this!
I don't know anything, just looking at that rock, I note that it's worn round and out of place, so it makes me think old. I'm also thinking it's sedimentary in origin and that water may be how it got to where it is and the shape it is.
As a retired physics and earth science teacher in high school, I just discovered this video and give top praise to you for your use of comparisons for scale and identification. People then immediately grasp your concepts, though they need geology training to understand the mineralogy and tectonics (I will look at your other videos, where you may have explained those things equally well. Keep up the great job. In contrast almost all science journalism is junk, just repeating the title in the first 5 paragraphs.
Thanks for the great feedback. It's always a challenge to provide enough background information and keep the video length manageable for me (which is about 4 minutes).
Frustrating when they don’t investigate things like that. Isn’t that kind of what it’s therefore? I don’t know if there’s some destination deadline, but traveling is half the fun
I am curious about how much more rounded the edges on the rock are than others visible in the photos. Some sort of weather might have occurred. Could sandstorms have smoothed the surface? Does that point to it being softer than other exposed rocks surrounding it? Or just older? It does seem like it is some sort of crystal structure as the dust does not seem to stick to it very well.
There are granite rocks in my yard that look similar, the striping is from slow convective shear during crystalization. Not much known granite on Mars either, but my guess is that it fell down from an impact elsewhere.
This may be a bit of a stretch, but...since we've already found plenty of meteorites here on Earth that originated from Mars (blown of the surface of Mars by massive impacts), is there a possibility that at least a few out-of-place-looking rocks on Mars are actually meteorites from Earth?
@@MarsGuy Admittedly I don't know what a fusion crust is (is it the dark matte charring on meteorites cause by atmospheric entry heating?), but I wasn't just talking about this specific rock, but maybe others scattered around that rovers haven't even checked out yet. More of a "Wouldn't it be cool of we did find one?" thought.
Too bad! The available data throughput is evidently a limitation of the system. You said that the images weren't uploaded for two sols -- and then not interpreted for two more, or was it deemed not worth backtracking then?
@@MarsGuy Yes, but had the rock of interest been spotted two sols after the picture was taken, it would only have taken two sols to backtrack to it instead of four.
This is a zebra marble like one from Mexico - rounded by fluviatile transport. I have a weathered one just like this in a box somewhere. Different from gneiss or porphyritic pebble the white part is seemingly more susceptible to erosion / weathering while the dark part is more resistant. The later might be due to the mineralization from high pressure fluids making them somewhat harder than the source rock.
This looks alot like the "paint" that other rocks that Mars Guy has featured have, but with a unique erosion pattern where the paint has dissipated. Possibly nothing more than that but shame that it wasn't further explored.
The stripes are the result of evolutionary pressure, as an adaptation to predation, to help them to blend into their surroundings and confound their predators. This implies that Mars was once savannah. Unfortunately this species was hunted to extinction, probably by early hunter-gatherers, as we can surmise by the rarity of the find.
Thanks
Thanks for your show of support for this channel!
I never thought I'd get to explore the surface of Mars when I was aged 70. This is just fantastic stuff. Thanks Mars guy.
Good news, you're only 37.3 years old when exploring from Mars!
Cool to hear! Glad you still care and i hope i and my kids will too!
Not quite 70 yet, but never thought I would be exploring Mars on a tiny handheld device that does way more than a Star Trek communicator...
Let's make it till we see people walking around on it. That would be wonderful.
I know, it's wonderful.
I love this channel, no clickbait and just science.
I mean, there's neither a zebra nor a unicorn in this video. /s

Given the lack of compositional information, you could still be right...
