dinosaur man Posted June 19, 2020 Share Posted June 19, 2020 I found these last year when I was in Nova Scotia, so I took some photos of them, there from Peggy’s Cove, Nova Scotia. Are they fossils? Link to comment Share on other sites More sharing options...

Rockwood Posted June 19, 2020 Share Posted June 19, 2020 I'm thinking these might be xenoliths in granite. 6 Link to comment Share on other sites More sharing options...
DPS Ammonite Posted June 19, 2020 Share Posted June 19, 2020 They are zenoliths or related enclaves in granite. Did you find any tourmaline? See article on the geology. https://novascotia.ca/natr/meb/pdf/ic09.asp 4 My goal is to leave no stone or fossil unturned.

TqB Posted June 19, 2020 Share Posted June 19, 2020 One more for xenoliths. I like the elongated one, not seen one like that before. 3 Tarquin Link to comment Share on other sites More sharing options...
doushantuo Posted June 19, 2020 Share Posted June 19, 2020 Xenoliths are ,petrologically speaking, hugely interesting green arrows:possible sources of xenoliths(generally speaking: the mantle is the source(so:NOT the crust) image slightly adapted from: Evidence from Antarctic mantle peridotite xenoliths for changes in mineralogy,geochemsistry and geothermal gradients beneath a developing rift S F Foley,A.V.Andronikov,D.E.Jacob,S.Melzer/Geochimica et Cosmochimica ACta,70,2006 2 Link to comment Share on other sites More sharing options...

dinosaur man Posted June 21, 2020 Author Share Posted June 21, 2020 Sorry for replying so late, I’ve been busy, but Thank you everyone! I think it might be just Geologic but I don’t have any other photos. On 2020-06-19 at 5:58 AM, DPS Ammonite said: They are zenoliths or related enclaves in granite. Did you find any tourmaline?
