Olivine is another type of volcanic rock. It is classified along with basalt as mafic, meaning that the dust will be high in magnesium and iron. Unlike basalt, which typically has around 2-3% magnesium, olivine will have composition percentages upwards of 50%.

This dust should be used sparingly and for the express purpose of adding magnesium to a potting mix or garden soil. The magnesium, along with the other trace elements will release slowly and does not easily leach away.
