Strange rock need help identifying

[Neava Terry]

I found this rock in a pile of unwanted rocks in Portales NM. The pile of rocks is very interesting but this one is crazy. I do not know where it was originally located.

Cool! Sorry I have I’m a total beginner and rock hunting and I have a bunch of mine to try to identify two so if you come up with an answer I would love to find out I have something similar that I’d like to share. Mine were found in a river on my property in Massachusetts. Ps This is my first post! Good Luck, Linda

Thanks Linda. This also is my first post.

Looks like it could be one of several types of similar looking rock a limestone, dolostone, sandstone, quartzite etc., try putting some vinegar on it and look for bubbling/fizzing or better yet muriatic acid, if it bubbles/fizzes can rule out sandstone and quartzite. also try to scratch it with a knife.

Ok Thanks. I will try that

Looks like vuggy quartz. Vugs are just holes in rock. Inside some of the holes, looks like druzy quartz, but hard to tell from picture.
