Son found this on the beach and is adamant its something special. About the size of a lump of coal with glass like speckals.
minus-squareCow_says_moo@lemmy.worldlinkfedilinkEnglisharrow-up13·1 year agoIt’s likely to be gabbro, a very common type of rock I’m afraid. Doesn’t mean it can’t be special to him! https://geology.com/rocks/gabbro.shtml
minus-squareMiarolitic@lemmy.worldlinkfedilinkEnglisharrow-up8·1 year agoYip definitely gabbro. OP, the light/ white mineral is plagioclase the dark almost black mineral is pyroxene. If you look at it in sunlight anything with a dark green colour is probably Olivine
