Green Hydrothermally Altered Basalt with Epidote from Almus Village, Turkey

This stone was identified by a few people as hydrothermally altered basalt with epidote. There's a superficial similarity to some of the spherulitic rhyolite / conglomerate that you sometimes find among the Black Sea pebbles. This stone is notably softer, however, and there is definitely no agate or related materials present. It's a remarkably coloured rock though and I am very happy to add it to my increasingly strange collection of Black Sea specimens.
