Fact sheet
The High Possil meteorite fell on 5th April 1804 and was recovered in two parts weighing 4.5 kg in total. The fall was heard by a number of people and witnessed by workmen in a quarry who were later able to recover it. The largest remaining fragment of the meteorite weighs 151 gm and is held by Glasgow University: Hunterian Museum. At the time, High Possil was a village on the northern outskirts of Glasgow, Scotland.
The High Possil meteorite is classified as an L6 ordinary chondrite, 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 olivine and pyroxene crystals and the most indistinct remnants of chondrules (not helped by the thickness of the section). In the reflected light view silvery grey metallic iron and golden yellow troilite are clearly visible. Less easy to see are the dull grey crystals of chromite.
