Is this stone powder made of basalt?
Hello Mahena63 How nice that you are interested in our products. Rock flour, primary rock flour or stone meal refers to very finely ground stone of any kind. The properties differ depending on the origin. For example, finely ground basalt, granite, diabase, gabbro or other deep and igneous rocks as well as limestone contain different trace elements. And now we hope you enjoy browsing our website. Your Migros Fachmarkt team

What is the exact composition? I am looking for a stone powder made from basic source rocks (no granite, gneiss or basalt).
Hello doedae, our rock flour consists of alkaline material with a pH value of 7.8. The rough composition is shown on the packaging. Best regards, your M-Infoline team
