Meteorites are stones of extraterrestrial origin that have survived the fall through Earth’s atmosphere. Meteorites can be big or small. Most meteorites derive from small astronomical objects called meteoroids, but they are also sometimes produced by impacts of asteroids. When it enters the atmosphere, impact pressure causes the body to heat up and emit light, thus forming a fireball, also known as a meteor or shooting/falling star.
If meteorites are recovered after being observed as they transited the atmosphere or impacted the Earth they are called falls. All other meteorites are known as finds. As of February 2010, there are approximately 1,086 witnessed falls having specimens in the world’s collections. In contrast, there are over 38,660 well-documented meteorite finds.
Meteorites have traditionally been divided into three broad categories: Nickel-Iron, Chondrite, and Pallasite. Modern classification schemes divide meteorites into groups according to their structure, chemical and isotopic composition and mineralogy.
Sikote-Alin Meteorites
It fell at 10:30 AM on February 12, 1947 in the foothills between Vladivostok & Khabarovsk.
It was a meteorite shower.
There are 122 craters (the largest is 28 meters in diameter x 6 meters deep) and 78 smaller pits
To date more than 8,000 iron meteorites weighing a total of 28+ metric tonnes have been collected at the site.
The largest recovered specimenweighs 1745 kilograms and the smallest is less than a miilameter across and weighs only 0.3 milligrams.
There are two types of Sikhote-Alin Meteorites. The most common is fragments. They littered the major crater field at a depth of just a few centimeters in the soil. They are the result of relatively large mass objects shattering on impact with the frozen ground and resemble pieces of shrapnel. The second more valuable class and harder to come by, are called individuals. They are pieces that did not break up during impact. Because of atmoispheric heating and the resulting ablation, the individuals developed smooth little indentations called rhegmaglypts.
Composition: Iron 84% Phosphorous 10% Nickle 6%
Sikhote-Alin Meteorites set into Sterling Silver Pendants start at $69.00 to $173.00
Sikhote-Alin Meteorites set into Sterling Silver Rings start at $69.00 to $200.00
Whitecourt, AB Meteorite
The impactor, originated as part of a core of an asteroid that was formed 4.5 billion years ago, most likely in the asteroid belt between the orbits of Mars and Jupiter. Breakup of the asteroid freed the rock that would eventually crash to Earth and form the Whitecourt crater.
Charcoal from the soil was radiocarbon dated to about 1100 years ago or sometime around 900 AD.
Composition: Iron 92% Nickle 8%
The crater, now deemed a Provincial Historic Resource Site and placed under protection, represents the only visible crater in Alberta, and only the 30th crater recognized in Canada, and the youngest. It is the only crater in Canada with associated meteorites, and amongst less than a dozen craters with meteorites worldwide.
Local residents contacted Dr. Chris Herd, the curator of the Alberta Meteorite Collection and a meteorite researcher at the University of Alberta in July 2007 after they had recovered several metallic fragments next to a large hole in the ground. Analysis of one of the fragments with the Scanning Electron Microscope confirmed that ti was a meteorite, and the finders accompanied Dr. Chris Herd and geomorphologist Dr. Duane Froese to the site. It became apparent that the hole in the ground was a crater.
Buzzard Coulee Meteorite
Buzzard Coulee meteorite fell on November 20, 2008. The fireball was first spotted around around 5:30 PM and was reported by people living in Alberta, Saskatchewan, Manitoba, and even Northern Dakota. It was 5 times as bright as a full moon..The object split into multiple pieces before widespread impact. It entered the atmosphere at approximately 14 kliometers per second and is estimated to be the size of a desk and had a mass of about 10 tonnes.
The Buzzard Coulee is located 40 kilometers straight south of Lloydminster, and near the hamlet of Lone Rock, Saskatchewan. The fall was named after the oldest-named geographical feature in the fall area. The first pieces of the rock were found by Ellen Milley, a U of C Master’s student. Milley was part of a team working with Dr. Alan Hidebrand, a U of C professor and Canadian Research Chair in Planetary Sciences, in the ice of a fish pond near Lone Rock. Ten pieces were initially found , the largest weighing 380 grams and the smallest was 10 grams. In total, more than one thousand meteorite fragments have been collected from the 10-tonne fireball, among them are two 13 kilograms (29 lb) fragments.[
Since the meteorite fell on the snow and ice, once it melted, the meteorite pieces were deposited on the surface of a farmer’s canola field. The owners of the farm, brothers Ian and Alex Mitchell, donated their astronomical find to the Royal Saskatchewan Museum.
In total, more than 1,000 fragments have been collected from the 10-tonne fireball, among them are two 13 kg fragments. Observations, combined with the physical evidence, give scientists a treasure trove of data that could give them a better understanding of the solar system. This event has set a new Canadian record for the most number of pieces recovered from a single meteorite fall.
