Help with id for rock from baja california

Hay Dusted I forgot to give some info. The rock is not attracted to neodyniums. The black brown melted crust is glassy. There are hair-line fractures throughout visible with a loop. I will do a scratch test for hardness along with spacific gravity and streak color and post the results.

looks like calcite.

Good afternoon! I hope you are still identifying unknown specimens for random people. I think it's pretty awesome of you! I found these in the trails by my house in Southern California (Orange County). I am thinking they are a variation of quartz but the rich white surface and the grey almost dull blue core is throwing me off. Your expertise would be much appreciated as I am dying to know!

Was found in Texas. Looks like a geode but with (hard/glassy) resin or tar inside. A neodymium magnet does not stick to it. Can someone help me identify it?

Looks like a calcite. Try your finger to scratch it. If it is soft and falls apart, it is calcite. If it is not soft, it could be variant of Feldspar.

It looks like a welded tuff - a volcanic rock. It looks like a lava cooled on the top of it later on.

Hi Dusted, I've had no luck at finding what this is. I found it midway on the baja california peninsula. View attachment 1662191 View attachment 1662192 View attachment 1662191

Found this rock in the Hualapai mountain in AZ. After examining it closely with a jewelers loupe, I noticed this tiny green spheres inside of a vug. Any idea what it could be? It's not bio, like insect eggs or anything. It is hard and part of the rock, like a mineral of some sort.

Does a magnet attract to it? can you scratch it with a pin or knife? also try a streak test.

try a streak test as well as hardness test. Does a magnet attract to it?

Its hard to tell what the dark material is but the whitish mineral is a feldspar.

Thx.

Looks like smithsonite or botroidal wavellite

Possibly slag.
Possible volcanics. The shiny black with holes looks like melted silica.

Sea weathered limestone.
Calcium from shells, bones etc. decay and form mats on ocean bottom and harden. Weather away smooth and vuggy. Look up texas holey rock.

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.
