Blog Update #11 - More rocks in our region

Not a lot to mention as far as the blog goes at this point, except that I've added photographs of three more stratigraphic units to the Rocks of the Region page. These are three of the many 'granites' in the Armidale district:

Gara Monzogranite --- Fickr Photos --- Stratigraphic Names Database
Glenburnie Leucomonzogranite --- Flickr Photos --- Stratigraphic Names Database; and
Rockvale Monzogranite --- Flickr Photos --- Stratigraphic Names Database
Typical landscape and outcrop characteristics of the Rockvale Monzogranite, Wollomombi area

On another note, while visiting a friends property near Armidale I observed a brecciated jasper in the Sandon Beds. I was aware of an abundance of jasper beds (red chert) in the region ever since my university days, however, I'd never seen a brecciated type and this was quite attractive. More to come in a week or so.
