Need help IDing this rock

This was found in N Central Kansas. It has larger crystal like rocks on one side and smaller sandstone like rocks on the underside.

The structure resembles Calcite. It's hard to see the terminations on the crystals clearly. A lovely specimen. Can you get close ups?

 

[Chelle67]

Yes I will get some closer pics. Hopefully they will be clearer this time

 

[BurntBear]

That would be great. It's an awesome specimen!

Some close ups, hope it helps you to see it. Thanks

I have one more thread of a rock that has had a lot of looks but no responses. Can you look at it?? I don't know how to link it to here.

Definitely looks like Calcite. Sure, I'll have a look.
