Olivine from Puig de la Banya de Boc volcano, Llorà, Sant Martí de Llémena, Catalonia, Spain
Bright green Olivine specimens from the Puig de la Banya de Boc volcano, Spain.
These are a typical olivine-pyroxene included in a basaltic strombolian projection bomb, if that means anything to you!
Essentially, these are formed as pieces of lava are ejected from a volcano; the 'bombs' can be anything from a few inches to several metres. The olivine is a xenolith, a rock trapped inside another rock while it is cooling - an older rock trapped inside a younger rock.
