[Sabre2th]

Belonged to a friend who kept this sitting in his shop office. No idea where it came from, but always liked it. His wife gave it to me after he passed. Weighs about 8 lbs, gray with deep red "veins". Will suck a cheap, weak magnet to it from a half inch or so..View attachment 1505475View attachment 1505476

Stumped? LOL

Hi,

I'm fairly new to the world of rocks, but have been showing an interest in them lately and would appreciate some help in identifying two rocks please.

They were both found on the Ceredigion coast in West Wales, one in New Quay and the other Cwmtydu. My daughter wanted to find some 'heart' shaped stones to take home and this is how I found them.

I think they're both sedimentary, but would like to know as much as possible about them please, including the red colouration on the larger rock.

Thanks for any help.

Hard to tell. Could be sedimentary, not familiar with the local geology. If so, possibly some kind of mudstone. (shale?)
The color is from iron-minerals staining the piece.

Pictures are kinda blurry. Magnetic due to magnetite. Do a streak test.

Hello recently I've decided to try to identify alot of the rocks I have found or have been given and a few have stumped me.

Thank you do much if you can identify them

A lot was not exaggerated. To make it simpler to me, limit the posts to about 3-4 minerals. Long lists are terrible work.

#1. To blurry to tell. Looks like there's mica in there.
#2 Blurrite.
#3 Beryl in quartz.
#4 Quartz?
#5 'Desert Rose'
#6 Sulphide. Will a knife scratch it?
#7 Sandstone(?)
#8 Granite
#9 Chalcedony
#10 Calcite, quartz or something else? Uncertain. Seen several minerals with that look.

Please help me identify what type of rock this is. Someone said that it is rhyolite but it does not really look like any images of rhyolite that I can find online.
However, it looks similar to images of pumice that I have found online.

Here's the link to several different photos of the same type of rock: https://photos.app.goo.gl/Kz9FjEIilbzsseqi2

I included one photo with my dogs in it for size reference.

Thanks!

What's a streak test?

curious as to what type of rock this is. it was found in north carolina in the piedmont slate belt area. i have posted another pic of this same rock in the geology sub forum.

What a cool site. Hoping you might be able to help identify these white rocks -- for sale at local aquarium fish shop here in Thailand (lady at shop didn't know what kind of rock it is). It's got kind of a grittier/sandy feel to it, not smooth like a quartz. My main hope is that it isn't calciferous, such as limestone, as I don't want raise the PH of my tank water. A test with household vinegar didn't result in any fizzing, but hoping to get an opinion of a pro, Thx!

Hello. I just joined this site, very cool! I found these rocks by where I live, any guesses?

I'd break of a piece just to see the fresh surface. Pumice or even scoria could be likely candidates.

Tumbled or water-rounded rocks, likely quartz. The rough surface might be natural or from the lack of going into finer grits during tumbling.

On the left - interesting. I'd like a close-up, less blurry pic. Could be breccia-ish material.
The others are quartz.

Greetings everyone,
I have been looking everywhere online for a way to easily identify a rock I found, and I stumbled across this thread.

This summer, while at the beach, I found a strangely white-ish/yellow-ish piece of rock. At first sight, it doesn't seem all that special... but I live on Prince-Edward-Island, Canada, where rocks typically does not have this kind of appearance and density. Upon closer look, I noticed how it had an unfamiliar feel and look, and decided to take it home for further investigation. Fast forward today, I never got around to getting someone to look at it, so I figured I'd give it a try.

The rock is roughly 7 inches wide by 6 inches long, and 3 inches thick (~17.7, 15.2, 7.6 in centimeters). The rock isn't exactly symmetrical, so this is just to give you a rough idea. It weighs around 1.8kg.







First time poster, so I hope I don't screw up anything. Thanks for the help!

This is the best I could do. I only have my cell phone to take photos with.

had this thing for as long as I can remember, curious to what it actually is🙂 Help ?!

Hi! My mother passed away earlier this year and we found a box full of these rocks in storage. We think the were may dad's (who died over a decade ago) who was an avid rock hunter. He did most of his rock hunting in Ontario and Quebec, Canada but it is entirely possible he obtained this somewhere else.

I'd be so grateful if you could help identify! Many thanks.
