HED Group - Meteorites from Vesta

This group comprises three closely related classes of achondrites collectively known as the "HED" group, standing for howardites, eucrites, and diogenites. The members of the HED group represent more evolved achondrites that have experienced extensive igneous processing similar to the magmatic rocks found here on Earth. Consequently, they closely resemble terrestrial igneous rocks such as basalts, dolerites, gabbros, and other igneous rocks of volcanic or plutonic origin. 

Polymict group: The eucrites of this group are polymict breccias that contain more than 90% eucritic material and less than 10% diogenitic clasts. This 9/1 ratio is an arbitrary dividing line to discriminate between polymict eucrites and the closely related howardites, the latter showing a more even distribution of eucritic and diogenitic clasts. However, polymict eucrites usually contain zoned pyroxenes within the basaltic clasts whereas the pyroxenes in howardites are mostly unzoned. Famous members of the polymict group are the falls of Pasamonte, USA, and Millbillillie, Australia. Other members were found in the hot deserts of Africa, e.g. Dar al Gani 480, Libya, and Smara, Western Sahara, a polymict fragmental breccia that was recovered by our team in April 2000. One of our more recent finds, NWA 049, has also been classified as a polymict eucrite - a unique meteorite that contains olivine and quartz. Continued research should reveal the secrets of its formation history.
