How rock forms

More biological than geological

I'm no geologist, but even I could see what was happening here. Mud (I won't say clay, because that has a specific meaning),turning to stone; hence, the common name "mudstone". Southern Wairarapa coast, a few weekends ago.

Like it could still be moulded. I'm very fond of the rock that was obviously scraped smooth by glaciers, as well.

Zhoen, those polished and scratched glacial rocks are really something. A reminder of the immense power of geological forces.

Hapi — thanks, and a nice day to you, too.
