Dear Siim, is that a gneiss or granite with magma flow structure? Porfiroblast is a term used for igneous rock only and augen means "like eyes", that is elliptic. On the other hand I see geometric feldspar in your picture, not elliptic. Zimbres
- I agree that this is not gneiss but rather a porphyry with some flow structure. --Md2perpe (talk) 16:15, 12 June 2022 (UTC)
