Sepiolite happens in clay regions like those produced by ice age glacial activity from orogeny. If there are great lakes with high clay contents, and a specific type of volcano deposits a lot of magnesium enriched ash into the lakes, the clay and the magnesium can dissolve and precipitate into high quantites of sepiolite precursor.
