Volcanic Rocks

I have been out with the walking group today and then for lunch afterwards, but I didn't take my camera because we were just walking in bushland along the fire trails in Nelson Bay

Here is a photo taken yesterday on my walk. The rocks are ignimbrite. formed from the cooling of pyroclastic material ejected from an explosive volcanic eruption. As the pyroclastic material settles it can build up thick layers, and if the temperature is sufficiently high (> 535°C) it can weld into rock. These rocks were formed 350 million years ago.

What a wonderful capture of this phenomenon with great shapes and textures.

[Rob Z]

Great image, rocks and info...

[Christine Louise]

Love the detail and texture of the rocks, especially the forground one

[Lesley]

Awesome! Extrusive rocks that haven’t been worn down by weather or water! Big fav

[Susan Wakely]

Great pov to show the colours and textures.

[Beryl Lloyd]

Such a wonderful find ! and a lovely shot!

[Joan Robillard]

Wonderful

[Dione Giorgio]

Beautiful shot, shapes and textures. I have seen Etna volcanic lava on several occasions during visits to Sicily they volcanic rocks are sharper and completely black.

[Tunia McClure]

hard to get a sense of that much time

[Shutterbug]

Wow! Thanks for the explanation. Very nice capture of this ancient rock.

[Dawn]

A nice find and capture

[gloria jones]

Great capture of the rugged looking rocks

[Babs]

@happypat It is similar in some ways Pat. Pumice is very fine volcanic ash and lighter than the rocks here. Ignimbrite is dense and white hot when it falls. It is produced in the same way but collects other rocks on its way which is why you get the weathered look

[Babs]

@sangwann I think Mount Etna rock is basalt which fits with its dark colour

[Carole Sandford]

Great details!

[Ann H. LeFevre]

Nice shot- it looks like someone carved a code into them.

[eDorre]

Great shot and composition and neat info!

These rocks are closed to home right next to our local marina but I didn't walk too far around the headland because the tide was coming in and I didn't want to get stuck.
