🔎 UNIDENTIFIED Found this rock

[Chio]

This rock caught my eye, found near the waters of the st Lawrence river in quebec, canada. After a quick rub it looks sandy-ish or something if you see the detail, its about an inch big and it got me curious as to what this may be exactly if anyone knows.. i have no idea other than maybe some sort of calcite or a sand stone since just by looking at it seems like a rock fully made of the sand crystals of those waters maybe.. thanks for any help

My first thought was sandstone as well. Hmm.

It looks like quartzite. Quartzite is metamorphosed sandstone. Sandstone is fairly soft and crumbles. Quartzite is a very hard rock. It’s also very common.
