DJ_curious Posted January 26, 2021 Share Posted January 26, 2021 (edited) I'm really curious about what this rock is -it was given to my dad years ago in Saudi Arabia. He was told it was a meteorite. I took photos of the front (I call it the front because it is the smooth side) and the back (the rougher side) of the rock. The back shows where I broke off a piece to get a look at the interior of the rock. The interior is not porous at all. It does not attract a magnet. Any ideas are welcome -thank you!

Bedrock Bob Posted January 27, 2021 Share Posted January 27, 2021 Hey DJ! That is a cool rock. Im not sure what it is. It could be basalt for sure. It has a nice crust on it. It does not look like a meteorite to me but it does have an interesting shape and crust. I can see how someone could think it was a meteorite for sure. It isn't slag. I only see a couple of holes. Just from the photo I'd say it was basalt. Quote Link to comment Share on other sites More sharing options...
Mikestang Posted January 27, 2021 Share Posted January 27, 2021 This one is tough to say from a photo, definitely worth having someone knowledgeable on meteorites look at in person. If it is a meteorite, it is an achondrite. 2 Quote Link to comment Share on other sites More sharing options...
Lunk Posted January 27, 2021 Share Posted January 27, 2021 (edited) The interior is way too light in color for typical basalt, although leucobasalt can be very light in color. Achondrite all the way...IF it is indeed a meteorite...expert analysis is required for that determination.

DarkSilicate Posted January 27, 2021 Share Posted January 27, 2021 Sure would be nice to see an update from OP on this suspect stone. Very interesting. 1 Quote Link to comment Share on other sites More sharing options...
DJ_curious Posted January 27, 2021 Author Share Posted January 27, 2021 (edited) Here’s more photos to show the size and some detail. It weighs about 725 grams and looks (from the exposed interior) and feels quite dense. I was debating sending in a sample for analysis, but after the feedback I think I will go ahead and get it tested. Thank you for the feedback and I’ll update the post once I know something more!

1515Art Posted January 27, 2021 Share Posted January 27, 2021 I’ve seen rocks in shops and museums in China that look very similar to the one you posted, the color varies by the type of mineral and location of the deposit and some can be very valuable. Of course it’s difficult to tell from a photo and I’m not familiar beyond seeing these a few times but could this be something similar?

No fusion crust, no regmaglypts and full of holes. Quote Link to comment Share on other sites More sharing options...

Bob, are you saying no to similar formations collected in China, or just that it’s not a meteorite? The lake rocks are terrestrial the ones in museums and around the forbidden city being highly prized in China they would also be collected elsewhere in the Middle East as well as copies.

Bedrock Bob Posted January 27, 2021 Share Posted January 27, 2021 Art, The OP posted a very interesting specimen. It is his thread and we are anxious to discuss his stone. Your rocks are cool. You seem to have a story to tell about them. I would love to discuss them with you in another thread over in the Rocks and Minerals section. 1 Quote Link to comment Share on other sites More sharing options...

1515Art Posted January 29, 2021 Share Posted January 29, 2021 (edited) Bob, I’m sorry I was just suggesting the OP’s specimen might be limestone, possibly old. Edited January 29, 2021 by 1515Art Quote Link to comment Share on other sites More sharing options...
1515Art Posted January 29, 2021 Share Posted January 29, 2021 (edited) My wife is over in Shanghai so I sent a couple of the OP’s pictures to her for an opinion, she’s very familiar with the This limestone and she thought it was indeed Taihu Limestone too. A few years back a small piece like that would have fetched a couple hundred dollars or more, since the pandemic prices have dropped. If it is legit, best if the OP’s not chipping off anymore pieces.

DJ_curious Posted January 29, 2021 Author Share Posted January 29, 2021 (edited) Hey Art, Thanks for the suggestion. I can definitely see the resemblance! My rock does have a glossy surface and is quite dense, even resonant (and it looks like these are attributes of Gongshi stones, particularly Lingbi limestone). I’m assuming that limestone can also form a dark crust? Thank you! Edited January 29, 2021 by DJ_curious Quote Link to comment Share on other sites More sharing options...

While they might look similar, I believe they have different origins. 1 Quote Link to comment Share on other sites More sharing options...
