Complete Set Of Three Types of Meteorites From The Asteroid Vesta. Meteorites have been identified as having originated from the moon, Mars, and the asteroid Vesta. No other asteroid or planet has been identified positively as the source of any known meteorite. Vesta is a very large asteroid with a diameter of over 326 miles and shows evidence of once having lava flow with a distinctive light and dark surface somewhat similar to our moon. It also has a gigantic impact crater that is so deep that it exposes the asteroid’s interior. There is a small group of stony meteorites called H.E.D.’s that show a similar spectral analysis to the surface composition of Vesta. H.E.D. stands for Howardite, Eucrite and Dragenite-three different types of chondrite, igneous basaltic rocks that formed from the huge collision that took place many millions of years ago. This collection consists of a 3.4 gm polished section of NUA 3117 which has partial fusion crust on one side and a mixture of rocks (breccia) from its formation. The Eucrite is represented by a 4.9 gm section cut and polished on both sides with a pale gray matrix and white and brown brecciated clasts. Lastly, the Diagenite which formed within the deep regions of Vesta’s crust is represented by a 4.6 gm polished section with a gray background and sizeable green pyrovene crystals and brownish-gray clasts. This important meteorite grouping was part of the Hupe collection of meteorites and is housed in a 6" x 5" Ryker mount. Add $20 for domestic shipping.
