METEORITES
A mere decade ago the "Earth sciences" were simply that; the study of the Earth, well, not any more. Pick up any modern geology book and you’ll find discussions of the Moon, planets and asteroids. Much of this new scientific turf is a legacy from astronomy where the solar nebula transformed into a series of worlds shaped more or less by familiar geological processes. "To Hold In Your Hands A Rock From The Depths Of Space,
A Piece Of Another World - That Is The Allure Of The Meteorite". Meteorites remain relatively unchanged since their formation some 4,600 million years or (4.6 billion years ago). Geological processes on Earth have erased all of the evidence of the Earth’s formation but meteorites still hold the evidence for both solar and planetary formation. They enable us to study hands-on Earth and planetary science in a unique way which can be done by no other practical method. The realm of the meteorite is one of unparalleled awe and inspiration. It is our fascination with our beginnings, the universe around us and our unconditional destiny in space that makes the science of meteoritics ever so popular and exciting. The latter half of the 20th century has seen a rise in the new science of meteoritics and impact geology. It is truly a hybrid science requiring a free exchange of ideas from a diverse group of established sciences. It has profoundly shaken the foundations of science, evolutionary biology and paleontology, and is changing our theory about our relationship to, and our place in the universe. Meteorites are tantalizing gifts from the depths of space, each one carrying new information about the solar system just waiting to be unwrapped. We are compelled, as a consequence of our in-born need to understand our surroundings, to open these sacred gifts and examine their contents, until such time as we can visit their parent bodies in person... before they visit us !!

TEKTITES
It is commonly accepted that tektites formed from vaporized terrestrial rock following a hypervelocity impact on Earth. One could think of tektites as meteorites from Earth in the sense that they were blasted from the Earth through impact and shaped by aerodynamic forces as they plummeted back through the atmosphere to create defined strewn fields. Previous theories espousing an origin from volcanic eruptions on the Moon have been adequately disputed through comparitive studies of the chemistry and mineralogy of lunar samples returned from the Moon by the Apollo astronauts. In fact, most tektite strewn fields have now been associated with a particular Earth impact structure with an established age directly relating the tektite to its corresponding ejecta deposit.
Lechatelierite, a form of fused quartz, and other relict mineral inclusions showing evidence of shock metamorphism, are found inside tektites, consisitent with an impact origin rather than one based on igneous volcanism. Additionally, the high-pressure polymorph of quartz known as coesite has been identified in tektites, indicating pressures greater than 2 GPa. Elemental abundance patterns along with size and shape characteristics of the mineral inclusions suggest that the parent material was a terrestrial, fine-grained, sedimentary deposit similar to a graywacke or loess.
