Situated near the Kutjevo vineyards lies the Vetovo quarry. It is unique due to 'amphibolite', a dark and tough rock that started to form from volcanic basalt. Within this quarry, it's been excavated since the mid-70s, to be used in road tarmac. You'll also see 'paragneiss'―a metamorphic rock with so-called 'banded layers' due to forces deep underground that took place >300 million years ago. To this day, this quarry is still active. With a bit of luck, you'd maybe even spot some rare 'garnets'―small red crystals that formed during metamorphic forces. And sometimes, the quarry walls will also reveal some rusty 'goethite'.
