re: Impressive anomalies.
You would have to be BLIND not to see the geological anomalies in almost every rock in the pan. They are so numerous and stunning, I can't even rationally comment on them, I'm still just trying to take them in and fit them into some sort of coherent rational framework for their structure, genesis and evolution.
When I come up with something geologically reasonable, I'll let you know.
Remember, phosphorus, something of the order of 10%, and water.
