Something Growing out of this rock??


Recommended Posts

I found this in a creek this summer here in  northern alberta Canada. Thought it looked weird and different. I have no idea what it is. Does anyone know what the dark stuff is that looks like its growing out of the larger piece? I also dont know what the lighter colored part is either. 

Would the inside of the rock be all dark like the bit coming out?

I'm not exactly sure what you have. It looks volcanic in origin but there's only one rock (or mineral)...not two. Looks like the same throughout but the upper part crystallized while the lower part did not. That's just imho. I'm sure others will chime in as always.

Dolomite caught up in a basaltic lava flow? No idea, but they both look like fairly nondiscript gray rocks, no very easily identifiable minerals as far as what photos would tell.

The grey looks like it could be chert. Have you tested for hardness?

No I haven't. What is the best way to do that? Scratch it with a nail or knife?

Is it possible to get basalt lava flow in a creek in an area with no volcanoes?

It could be from 1000s and 1000s of years ago and volcanoes were most everywhere then,  or brought to the area by glaciers
