Metal Crater Floors

What I think happened is right before Mars lost it atmosphere the oceans and seas of mars rushed over the land and ripped some of these floors into rubble. Lets take a look at one of the images that convinced me of this. This image clearly shows the floor of a crater ripped open like a tin can. Now rocks do not rip open like this only some type of metal.

Here is a side view of the end of one floor. It looks like at this end a lot of the floor was washed away.

Here is a view looking straight into a small crater but you can see the floor which has a difference appearance than the actual ground.

Here are a couple of images that also look similar to the others:

Here is an interesting orbiter image. It also shows some sort of metal floor.
