From Pathfinder Wiki
There are three major types of sand:
- Terregenous
- This type of sand is eroded from rocks (sedimentary, volcanic, and crystalline), and is generally transported by water. Most sand is of this type.
- Carbonate
- This type of sand has organic origins, being made from ground sea shells, corals, and other marine sources.
- Pyroclastic
- This type of sand is created when volcanoes erupt and blow their ash (pyroclastic sand) into the atmosphere.
