Here are a few pictures of the type of rock that the natives used for their stone tools, I have just found out that they use to get it a few hours from were I live. I was wondering if anyone knows what type of rock it is? I have been told that it is basalt by a few people but someone else tried to tell me its obsidian but I don’t think it is, I have never seen obsidian that looks like that before. Thanks.

I'm sorry I don't know for sure. There are others on this site that have been around the knapping world. I think it could be basalt or rhyolite. But both aren't too common here in TX.

Looks an awful lot like dacite to me.

Newbow, you could be right. There's not much of it here either. Does dacite have inclusions or is it grainy. I've knapped a few pieces but maybe they were Top Shelf . I'm not contradicting only asking . I'm good with TX material but at a loss to most others.

The only dacite I have worked comes from near Glass Buttes in central Oregon. It is generally less grainy than the closeup photo shows and has few inclusions; just the odd ash pocket on occation. Having said that, it still looks like dacite. Other than being less grainy, I have some in my shed that look just like those pictured.

thats basalt . love the stuff. if you have a good source for it let me know. been looking a long time for some more.

Hornstone??
-
That looks like a high grade Basalt or low grade Dacite to me. I've gotten both from west Texas before.

Thanks for the replies.
