Writeup from MB 98:

Daule        1°52’15.2"S, 79°57’27.2"W

Guayas, Ecuador

Fell: 23 March 2008, ~9 AM local time (UT-5)

Classification: Ordinary chondrite (L5)

History: People in Daule and the surrounding region heard a series of loud detonations and, moments later, two stones were seen to fall. A single stone fell outside a home next to the Daule River. The homeowner was less than 5 m from the stone, which penetrated nearly 1 m into the mud and bounced out, landing on the surface. He picked up the stone moments later. Another stone was reported to have impacted into a flooded rice paddy and sent a fountain of water several meters in the air; this stone has not been recovered.

Physical characteristics: The recovered stone weighed 6.58 kg.

Petrography (Jeff Grossman, USGS): A shocked ordinary chondrite with abundant melt veins; shock stage, S4; weathering grade, W0.

Geochemistry: Olivine, Fa24.5±0.5 (n=41); low-Ca pyroxene, Fs20.8±0.5 Wo1.4±0.2 (n=12).

Classification: L5 chondrite.

Specimens: 20 g, SI; main mass, MFarmer.
