I found this in southern illinois and cant figure out what it it. Keep in mind the white thats in it is white and there are some sparkles in it also that picture dont show. Also its not granite. 20190624_161215.jpg20190624_161304.jpg20190624_161221.jpg
 

I'm never very good with pics of rocks, but it looks like Triassic red sandstone, from the age of the dinosaurs.

It could be porphyritic rhyolite with quartz (the sparkle) and some kind of feldspar( the white).
