That's certainly more likely. The abundance of vesicles would be characteristic of volcanic origin. That light colored inclusion though, that's what makes this specimen interesting.

Hi, i will make it more interesting. What you can't see on the photo's is that the rock has tiny melted and broken quartz particles in the whole rock. and the wall of the  gass bubbles are melted smooth glassy like. I do kep finding strange rocks or do the find me, hahaaha

If you're seeing quartz particles, a microscopic examination would determine if they are shocked. Shocked quartz is indicative of extreme stress, i.e. the result of a high energy impact. If you're able to find shocked quartz in any of your finds, that would be good evidence of meteoritic origin. Or, at the very least, an impactite resulting from the same.

how rare is it to find a impactite in the netherlands or in general? i will take it to the natural museum and put it under the licht microscop to look for shock features. Thanks.
