Again, Petrology Field Trip

Saturday, November 29, 2008 Geophysics 2007 had a Petrology field trip for the second time. It was about sedimentary rocks, which are formed by deposition and consolidation of transported material which had been weathered. Our destination was Buyutan, Gedang Sari, Gunung Kidul where there were many interesting places to learn about rock types, especially sedimentary rocks. For the first, was about tuffaceous sandstone and then after lunch we continued our trip and found sedimentary rocks that consist of conglomerate, clam fossil, sandstone, and some igneous rocks... Then we went to different place to observe what we called ripple mark, washed out, load out, and graded sedimentary layer.

That's all, sorry for that little post because I am now not really keen on posting, just because of my flu, hiks...
