Paleo DNA, from what source?

Um, it's actually a "paleo" thing.

The latter are more similar to major sulphide deposits that are being mined on land today but which were once formed at spreading centres of paleo-oceans.

So I talked to some paleo friends, and I've been using an alternating combination of water jetting, muriatic acid and calcium baths.

Wadi Al Batin is a regionally important water collection and transport system, and the geological materials in the Wadi are generally more porous than those in the other areas.
