The Ashdon meteorite fell on 9th March 1923. It is an ordinary chondrite weighing 1.3 kg and shows remarkable flow lines on its exterior where melting occurred during its passage through the Earth's atmosphere. Ashdon is near Saffron Walden, Essex, England.
The Ashdon meteorite is classified as an L6 meaning it has a low iron content (5-10%) and indistinct chondrules that have been metamorphosed under conditions capable of homogenising all mineral compositions. Look in PPL to see a few chondrules (rounded features - rotation 1) consisting of olivine and pyroxene crystals. The thin section is unpolished, so there is no reflected light view. However, in PPL the rusty marks around the opaque (black) crystals highlight the location of the metallic iron in this sample.
