Collecting tips
- Look for Peat Deposits. Lignite often occurs in geological settings where peat is currently forming or has formed in the past, such as ancient swamps or bogs.
- Examine Outcrops. Look for exposed sedimentary layers in road cuts, river banks, or mining areas. Lignite beds can be several meters thick.
- Identify Plant Remains. The presence of visible plant structures (leaves, wood fragments) within a brown, earthy rock is a strong indicator of lignite.
- Check for Friability. Lignite is typically soft and crumbles easily. It may also feel lighter than other rocks due to its porosity and high moisture content.

- Brown to brownish-black
- Luster:
