2. Presence of hydrocarbons
3. Presence of carbon
4. Presence of salt pans

The presence of traces of carbon may indicate that there was life once thriving on its surface ( which however is not possible in case of a meteorite because of its size). The absence of any of the above listed items will indicate that the surface of the meteorite is devoid of any life.
