The map was made using NASA data.Here, Dr G. The color highlights the different groups of meteorites according to modern classification. The interactive map below shows the location of all registered meteorite collisions on Earth. There are 15 chondrite groups, including eight carbonaceous (CI, CM, CO, CV, CK, CR, CH, CB), three ordinary (H, L, LL), two enstatites (EH, EL), and R and K chondrites. A more detailed classification of meteorites is primarily based on their mineralogical and petrographic characteristics and their whole-rock chemical and O-isotopic compositions.Īccording to the more complex modern classification system, meteorites are classified into chondrites, primitive achondrites, and achondrites. iron meteorites (the second most frequent type of meteorite and have the most extensive masses)Įach type can be divided into various classes and groups.stony meteorites (the most frequent type of meteorite they can be of a reasonably large mass and consist primarily of the silicate minerals olivine and pyroxene with feldspar and scattered nickel-iron).There are three principal types of meteorites, depending on how much metal or stony silicate mineral is present: The largest discovered meteorite weighs sixty tonnes and yet remains where it fell, at Hoba in Namibia. The map below shows the median mass of the fallen meteorites by country Top 20 countries/landmasses by the median mass of the fallen meteorites. Top 20 countries/landmasses by the total mass of all the fallen meteorites. Therefore, the median mass of meteorites from Antarctica is 13.43 grams. In Antarctica, all meteorites are gathered regardless of size. The field for Antarctica decreases significantly. The geographic concentration of meteorites is significantly different if assessed by mass instead of by number. Top 20 countries/landmasses by the number found meteorites Rank The map below shows the number of meteorites falls by country. Oman’s findings include 1/3 of all known lunar meteorites and some of the examples from Mars. During the last 10 years, Oman has yielded almost 1/5 of the globe’s meteorites. Oman comes after Antarctica in terms of the number of meteorites found.

Moreover, meteorites are more straightforward to discover in deserts than in areas with lots of vegetation or other rocks.įor example, more than 22,000 meteorites have been found in Antarctica alone. Deserts are areas that accumulate meteorites over thousands of years, and nothing much happens to the fallen meteorite. Were are meteorites are found by number?Īn overwhelming number of meteorites are found in deserts, including ice deserts such as Antarctica. Most meteorites fall in mountainous or remote landscapes and have a lower probability of being found. About five hundred meteorites of moderate size would strike our planet’s surface each year, of which 150 would fall on the landmass, and less than ten would be found. Top 20 countries/landmasses by the median mass of the fallen meteorites.Īpproximately 500 tonnes of meteoritic wreckage fall to the planet each day, much of it as little cosmic dust and micrometeorites that sink into the ocean.Top 20 countries/landmasses by the total mass of all the fallen meteorites.Top 20 countries/landmasses by the number found meteorites.Were are meteorites are found by number?.
