Micrograph of the Month: Mixed fuels

It's been too long since I've looked at any new thin section samples, but today I had the chance to look at some new stuff from Catalhoyuk. Here are some lovely mixed fuel deposits from an external area, showing A. wood charcoal (Quercus?), with microcharcoal and phytoliths from grasses and sedges. B. is a close up of the ash to try and show some of the phytoliths but it is hard to get a good photo in focus even though the slide is only 30 microns thick. Probably redeposited given the random orientation of the phytoliths.
