Basaltic rock
* are the most productive aquifers in volcanic rocks.
* contain too little silica to be reactive.

* reacting with geothermally heated water can form chemicals that can support life.

Basement rock

* is that which forms the lower part of the crust.

Beach rock

* is the host material of most beach fossils.

### rock:

Bedrock
* Some bedrocks are acidic, such as granites, and others are basic dolomites and limestones.
* can also become broken and fractured, creating spaces that can fill with water
  - cause a perched water table
* consists of a sequence of cherty limestones and shales of the Permian age
  - interbedded limestones, siltstones, and shales
  - sandstone and shale
  - primarily of basalt, andesite or basaltic tuffs
