Santa Lucia (2008)        31°32’08"S, 68°29’22"W

San Juan, Argentina

Fell: 23 January 2008, 17:20 hours daylight time (UT-3)

Classification: Ordinary chondrite (L6)

History: A fireball followed by a thunder-like sound was witnessed in the area at 17:20 hours local time. At Santa Lucia, a group of children felt an air wave before they found a black stone lying near their home. The stone was then picked up by them and 2 days later, it was brought to CASLEO Institute for investigation. Several pieces with more than 4 kg total mass have been recovered in the area of Santa Lucia.

Physical characteristics: The stone investigated at CASLEO is an individual piece weighing 1900 g and is totally covered by fusion crust. Its interior is light-gray with grains of fresh metal and sulfide.

Petrography: (F. Brandstätter, NHMV, and M. E. Varela, CASLEO): Monomict breccia with strongly recrystallized texture. Only a few chondrules (mainly radial pyroxene) are visible. In places, twinned plagioclase is present. Most silicate grains are intensively fractured. Troilite occurs as polycrystalline grains.

Mineral compositions: EPMA: Olivine (Fa24.4), pyroxene (Fs20.7 Wo1.5).

Magnetic susceptibility (Jérôme Gattacceca, CEREGE): Measurement of two fragments gave log χ = 4.65.

Classification: Ordinary chondrite (L6); weakly shocked; W0.

Specimens: 20 g and one thin section are on deposit at NHMV. A mass of 1526 g is at the La Plata Museum (La Plata, Argentina) and 354 g is kept at CASLEO. A mass of 2230 g (several pieces) is held by an anonymous finder. Other pieces remain in the hands of local people.
