Writeup from MB 105:

La Yesera 005        23°17.7’S, 70°29.2’W

Antofagasta, Chile

Find: 2003 Apr

Classification: Iron meteorite (IVA)

History: Found by Rodrigo Martinezin in 2003, while he was searching for meteorites. Informally known as "Cuenca del Tiburon."

Physical characteristics: A single, roughly parallelepipedic metallic mass.

Petrography: Fine octahedrite with minor fine inclusions of schreibersite and troilite. Bandwidth is 0.3-0.5 mm.

Geochemistry: Bulk composition (INAA, J.T. Wasson, UCLA): Co = 3.89 mg/g; Ni = 74.5 mg/g; Ga = 1.99 μg/g; As = 3.26 μg/g; Ir = 2.62 μg/g; Au = 0.844 μg/g; Ge not determined. The meteorite plots in the IVA fields on element-Au diagrams. Its composition is slightly lower in Au and As but the same in Ni as the mean of two Gibeons used to define the low Au, As end of the Gibeon compositional range. Cosmogenic 36Cl content of 24.8 dpm/kg (measured at CEREGE) clearly excludes it from being a piece of Gibeon, which has no detectable 36Cl.

Classification: Iron, IVA, fine octahedrite

Specimens: Main mass in MMC, type specimen 22 g in CEREGE, 1.2 g INAA slab in UCLA
