Yeah.

Recently came out.

The...

The minerals that were there in large veins of what are probably a mineral called gypsum and associated minerals are minerals that form through a fluid.

Precipitation, they're evaporating minerals.

They have to come out of this fluid that is there, and the fluid's evaporating.

And other minerals that are there, such as vivianite, which is a phosphate mineral.

Here we go, phosphorus again.

One of the...

It's a hydrated mineral, so it has water attached to it, which makes it structure.

And then gregite is another mineral that form, and that's an iron sulfur-rich mineral.

But that is an interesting mineral because it's on a pathway.

The final product forming would be pyrite, which everybody knows is school scope.

The mineral before that is not an all right, big name, but that mineral was recently discovered in both Rugu and Bennu for the first time.

Now, why is this mineral important?

Because it's sampling different abundances of oxygen that is around in order to produce itself.

Oh, that's a great question.

We assume it's coming from a fluid interaction, a fluid that has evolved.

But how that fluid's evolving, I don't know.

When that fluid evolved, I don't know.
