The meteorite was found in the town of Gancedo, 1,085km north of capital Buenos Aires, Mario Vesconi, President of the Astronomy Association of Chaco, said on Monday.
"While we hoped for weights above what had been registered, we did not expect it to exceed 30 tons," Vesconi said, adding that "the size and weight surprised us", Xinhua news agency reported.
"It was in Campo del Cielo, where a shower of metallic meteorites fell around 4,000 years ago," Vesconi added.
The meteorite will be weighed again to ensure an accurate measurement.
The largest meteorite ever found is called Hoba, weighing 66 tons in Namibia, Africa.
Update with additional details on the Gancedo Meteorite
The Gancedo Meteorite is believed to be the second largest meteorite ever discovered. A previously discovered meteorite in the El Chaco area weight 28,84 tons. The researchers had to be very careful in recovering the metallic meteorite because of the ground water coming into the crater according to Argentina newspaper La Nacion.
Now Argentina has two of the world's largest meteorites. Only the Hoba meteorite discovered is larger with 66 tons. There are possibly more meteorites to be discovered in the El Chaco area.
