Experts say rock-like meteor fragments are rarely round but rather have highly irregular shapes. A fragment that fell recently will have a paper-thin black coat from when it superheated while speeding through the atmosphere. A simple test is to scratch it against the unglazed side of a ceramic tile. A meteorite will not leave a streak.

Deserts are ideal to find meteorites

It may be one of the world's most inhospitable environments for man, but conditions in the scorching deserts of southern Abu Dhabi are ideal for preserving the fragments of rock and metal that plummet to the Earth's surface from space.
With little rainfall to corrode them, and scant change to the landscape, meteorites can lie undisturbed in deserts for millennia. Thousands have been found in the Empty Quarter in Oman and the deserts of Libya, but until last year there had been no official survey in the UAE.

Amateur astronomer and author Anthony Whyte says that the exploration of space begins in our own backyard. It's an epic mystery that can fill in the missing pieces of our past and tell how the landscape was, and is, forever changed by each impact.
His new book, The Meteorites of Alberta, is a journey that delves into the history of this province and the explorers who are still peeling away the legends to find the facts.

Imilac Meteorites
Permalink  
 

Imilac is a stony-iron that meteoriticists group as a Pallasite. Pallasites are meteorites that are mixtures of metal and silicates, usually olivine grains. Imilac is also a "PMG," which refers to a Pallasite belonging to the main chemical group. Searchers have turned up roughly 900 kilograms of Imilac meteorites over the years. The largest known specimen recovered to date, 198 kilograms, is in the British Museum. A second large Imilac - 95 kg - is in Copiapo, Chile, a mining town and the capital of the Atacama region. Imilac material ranks third in mass among Pallasite meteorites recovered, after Brenham and Huckitta. Imilac is a stable meteorite, having spent most of its "life" in a dry desert environment.
