Banded Iron (Iron Ore)

Transcript:

Sarah: Our diver has some minecarts, and our patented minecart technology means we don't have to worry about being able to breathe underwater. I was wondering if I needed to bring my scuba suit or something, so that's good, cause I didn't pack that. So there is another formation that we're going to see as we come around the corner that has appeared since the last time we were in this world. 

Kim: Wow we are going deep. 

Sarah: Mmm-hmm. And so over here we have this nice formation of iron.  

Kim: Oooh.

Sarah: And so we have this banded iron formation under the water here, and I was wondering if there is anything that you wanted to say about it. 

Kim: For sure. So banded iron formations are really interesting rocks. They form a long time ago and this is some -- the bands are basically chert, so iron-poor chert, and then some iron rich layers, and those layers form over and over again deep within ancient oceans.

Sarah: So there is our banded iron and the iron ore that is in the rom collections database that our friends can learn about.

Kim: Very cool, yeah!
