Only 1 fragment was found in 1951 during an excavation of a water reservoir. The total weight was 755 kg. In 1992 this meteorite was sold to the American meteorite collector Robert Haag. The Esquel meteorite was then completely sawed into smalle, as well as large slices. Pallasites are a type of stony-iron meteorites with inclusions made of Olivine (peridot) crystals. The origins of pallasites is still a cause for debate, but the most popular theory is that they were created during an impact with a planetoid of differing makeup in which there was a mixing of core and crust. Esquel is known as the most beautiful and most stable of pallasites.
