Scientific paper

We report the results of a survey of clasts and large (>5mm) chondrules (macrochondrules) within the 833 ordinary chondrites of the Natural History Museum collection. Thirty six macrochondrules and 24 clasts were identified and studied. Macrochondrules have textures and mineral assemblages like normal chondrules and so share a common origin. Clasts show evidence for fracturing from larger bodies and can be classified as either: 1. chemically fractionated if they have major and trace element compositions differing substantially from most chondrules and clasts; 2. impact-melt clasts have microporphyritic textures and signs that indicate they are derived from shock-melted chondritic material; 3. microporhyritic clasts are similar to the last category but lack evidence for derivation through shock melting; 4. indeterminate clasts form a diverse class which includes all those clasts that do not fit into the other categories.
