Yay, Crosssections!

Up until this week my uni project has largely been focusing upon the minerals within my rocks, and the chemical compositions thereof, and what these can tell us about the conditions under which the minerals grew. But all good petrology needs something in the way of geological context. While there was some very good structural work done in the Collingwood River region of Tasmania back in the 1960's, that was before it became fashionable to use the textures in mylonites to determine the relative movement directions across the fault (which created the mylonitic textures in the first place). Therefore it is necessary to draft new cross sections (using the original data measured way back when, since the orientations of the rocks exposed at the surface hasn't changed). Why new sections? Because it is needful to show the sections along a line parallel with the lineations in the mylonites, so that the movement directions can be shown on the sections, and some of the understanding of the relationships of the various units has changed over the years.

Therefore this week I got to play with coloring and drawing and use skills learned in Structural Geology, one of my favourite undergraduate classes. Here it is still in the draft stage, the result of a fun week of play time in the name of science!

off for a night of dancing!

Today slipped by terribly quickly, I managed to accomplish some uni work and some much needed house cleaning, and now it is time to head off to tonight's entertainment. Should be a fun evening, the band is delightful, and they do actually set up an old-time veranda, complete with tin wash tub and scrubbing board, rocking chairs, etc.
