We should be careful that the evidence so far is conclusive of ground water not surface water
Unless I missed something.
Do I have it right that that the evidence for water found in rocks is:
1. Spheres called concretions that grew in voids from water.
2. Tabular shaped holes where crystals grew and were destroyed by water.
3. High amounts of sulfur salts which has higher traces of water.
4. Jarosite which needs water to form.
Just trying to get it right.
