688 grams.   L6

TKW 45 kg. Observed fall 6 January 1985, Entre Rios, Argentina.


Steve writes:
La Criolla fell at 6:15 pm on January 6, 1985 over Entre Rios in Argentina. One of the more spectacular falls of the latter part of the 20th century, it showered tens of crusted stones over a 4 x 6 mile elliptical strewn field east of Estancion La Criolla and west of Concordia. Witnesses reported a bright fireball and multiple sonic detonations. An almost 2 kg individual augured itself into the local soccer field while a 750 gram stone crashed through the roof and destroyed a door of a farmhouse as a family was dining, causing them to run from the house in fear for their lives after missing a woman by only fifteen feet.

La Criolla was one of Bob Haag’s earliest recoveries. Haag purchased a 6.1 kg specimen from the local mayor, a 7 kg specimen from a coffee shop, a 2.6 kg specimen from a farmer, then subsequently personally collected an additional fifty one stones totaling 34 kg (he later described how the locals were terrified by the way the meteorite fell onto their countryside, making it easy to convince people to part with their stones). Photos 1 and 2 show a 688 gram complete individual.

La Criolla is an L6 olivine-hypersthene chondrite with a shock rating of S4 and a weathering rating of W2. It has more chondrules than one would expect from a type 6, and it also has prolific tiny shock veins and metal flecks and blebs (Photos 3 and 4 show two examples of the latter in the crust). Some portions even contain obvious shock melt, as seen in Photo 5’s small 1.58 gram fusion crusted slice. Consequently many consider La Criolla to be one of the more aesthetically pleasing of the L6 chondrites.
