Wordless Wednesday – Rocks

by Deb on April 6, 2011

Gold

These are some of the rocks in the garden at the WA Museum that the girls had a great time climbing all over. The one above is quartz, with veins of gold running through.

crystals

Metamorphic rock, crystals grew around a centre until they touched each other.

These crystals started growing in molten rock, getting larger and larger until they touched each other.

Sedimentary

Ancient layers of sand that turned to stone, then were washed away by wind and rain.

Possibly from an ancient lakebed or sea, thin layers of sand are brought in by rivers and settle, gradually compacting and turning to stone. Then they are dried and the water begins the opposite,  washing the tiny grains away again.

Meteorite

Left over from when the solar system formed.

And a meteorite, formed far out in space, melting on its way through the atmosphere, then weathered until we found and collected it.

Love those photos, rocks have always been a big favourite for me and now the Aspie teen has been a member of the lapidary & gem club for 2 years due to his love of rocks 🙂

I love rocks, always wished I could do a bit more geology at uni because they are fascinating. I completely lack the co-ordination to be a lapidary!

Unreal! Nature is a true artist, isn’t she?

Great pics. My grandmother used to have a segment of rock at her place looking very similar to #2. Now I’m a little more curious about it!
