rockofages Posted May 27, 2018 Share Posted May 27, 2018 I keep finding these bulky rocks with weird holes. Could it be something other than lava rock? 3"x4" Westchester, NY Link to comment Share on other sites More sharing options...
GeschWhat Posted May 27, 2018 Share Posted May 27, 2018 I see holes like this in limestone around my area. If I remember correctly, the holes can be formed in that material as water percolates through the limestone dissolving the softer material. There are often times little crystals that form in the voids. There are others here more well versed and know the geology of your area better.

Tidgy's Dad Posted May 27, 2018 Share Posted May 27, 2018 In this case I think it is a volcanic rock and the vesicles are formed by gas bubbles in the molten rock. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
rockofages Posted May 27, 2018 Author Share Posted May 27, 2018 If it is lava rock, there is a lot of it in Westchester, NY. I wonder if that is deposited from glaciers. It must be. Link to comment Share on other sites More sharing options...
Fossildude19 Posted May 27, 2018 Share Posted May 27, 2018 Not necessarily. If you Google Igneous intrusions Westchester NY, plenty of geologic articles come up. 4 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."
