Writeup

Writeup from AMN 27(1):

Sample No.:	LAP 02430
Location:	LaPaz Icefield
Field No.:	15919
Dimensions (cm):	1.0x0.75x0.5
Weight (g):	1.277
Meteorite Type:	L6 Chondrite (Metal Rich)

Macroscopic Description: Kathleen McBride
50% of this ordinary chondrite’s exterior is covered with brown/black fusion crust. The interior is rusty and lumpy with metal and dark shiny areas.

Thin Section (,3) Description: Tim McCoy, Linda Welzenbach
The section consists of a large metal fragment (90% of sample) with a small area of highly recrystallized chondritic material. The mineral compositions are homogenous; olivine is Fa₂₄ and orthopyroxene is Fs₂₁. The meteorite is probably an unrepresentative fragment of an L6 chondrite.
