Description: 

This single stone of 767 grams fell on 15th May 1991 in the village of Glatton, 15 km SSW of Peterborough, Cambridgeshire, England. It landed in the garden of Mr Pettifor who heard it crash through a hedge and found it, still warm, in a pit about 2 cm deep. The meteorite has a granular texture and was acquired for the nation by the Natural History Museum in London. 

The Glatton meteorite is classified as an L6 chondritic meteorite, 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 chondrules consisting of olivine and pyroxene crystals. Rotation 1 shows parts of three chondrules whereas rotation 2 shows a single, very indistinct chondrule and some blocky pyroxene and olivine crystals. The reflected light view reveals the location of the metallic iron in this sample (silvery grey mineral) and troilite (a golden yellow sulphide mineral).
