Name: LaPaz Icefield 03719 This is an OFFICIAL meteorite name. Abbreviation: LAP 03719 Observed fall: No Year found: 2003 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 62 g
Macroscopic Description: Kathleen McBride
The exterior has 40% fusion crust, gray-brown in color. The interior is a white matrix with brown circular to oval shaped inclusions. The matrix is stained brown and has lots of rust/weathering.
Thin Section (,2) Description: Tim McCoy, Linda Welzenbach
The section is an unbrecciated rock consisting of essentially FeO-free enstatite, diopside and olivine with minor metal, troilite, daubreelite and alabandite. Enstatites reach 1 cm in maximum dimension and contacts between enstatite grains are often interfingering. Blebby diopside exsolution occurs within enstatite and at enstatite-enstatite grain boundaries. Olivine, which occupies ~20% of the section, reaches 3 mm. Although the pyroxene textures are reminiscent of some aubrite clasts, the unbrecciated nature, texture and olivine abundance in this aubrite are unique.
