Timelapse of a river change course

Timelapse of a river changing course. I stole it from 9gag and who knows where they stole it from?

Date idea 8/10/2014 - Orbticular Diorite, Sweden

orbicular diorite - N57° 22.930 E15° 36.100

Counter top geology - Rapakivi granite

Large (up to 6cm) circular orthoclase feldspars (pink) phenocrysts with growth rings of opaque minerals (hornblende?). Many of the feldspars have a plagioclase feldspar (green) rim. Some also display a growth ring of plagioclase. The rest of the granite consists of large (1cm) crystals of dark minerals and orthoclase.

Small growth rim of plagioclase suggests alternating temperature/chemistry of the melt?

This granite is located on the side of Bran Diamonds on Swanston Street, Melbourne. It's one of my favourite facias in the city. I always thought it was a lovely weathered example of orbituclar granite however when confirming it's origin I found this page and this page both of which suggest this is in fact Rapakivi Granite.

Date Idea 3/9/2014 - Vermilion Cliffs, Arizona

According to Beautiful Places to Visit.com, permits are required to access the vermilion cliffs and only 20 are issued each day. Looks like a beautiful sedimentary landform. I'd love to go explore this properly - look at that unconforrmity!

Date idea 27/8/2014 - Petrified Forest

I've spent some time teaching at the Fossilised Forest on the shore platform at Inverloch, Victoria. It's quite a sight to see huge tree trunks that have been knocked over in a flooding event and preserved with the mud still clinging to the rocks. I've recently found out about an even more impressive fossilized trees - The Arizona Petrified Forest (http://www.nps.gov/pefo/index.htm). Not only does this place have a forest of preserved trees, it also has some amazing fossils too.

Date Idea 20/8/2014 - Icelandic volcanos

I've probably posted about Iceland already, but all geologists should visit this country - where else can you stand on a divergent plate boundary AND the results of a mantle plume? I recently got linked this update about recent activity and the possibility of another large volcano.

Not only great geology but also great scenery - Ásbyrgi 

Date Idea 13/8/14 - Meteorites

Having read a post on geology.com regarding starting a meteorite collect, I've deiced that hunting meteorites might make and enjoyable date activity. Not only can this be done anywhere (some places are better than others), there are also many different types to collect!

A couple of the researchers at Monash University go out to the Nullibore to hunt meteorites. This location has some distinct advantages. Due to the limited erosion and weathering, meteorites are preserved in-situ for a long long time. This increases the chances of finding them. Other locations that would be productive are known strewnfields. Areas where meteorite fragments have already been found where more might be discovered. Recently, 10th July 2014, a meteorite was seen from Melbourne and Sydney (as reported in The Age newspaper). It was recorded by a number of people. A meteorite this recent would be amazing to find.
