Trace Element Chemistry of Larkman Nunatuk (LAR) 12011, a New Olivine-Phyric Shergottite

Abstract

The olivine-phyric shergottite LAR12011 was found at Larkman Nunatuk during the 2012 ANSMET expedition [1]. The preliminary analysis of LAR12011 presented in [1] and oxygen isotope analysis in [2] confirms its Martian origin. This new sample is paired with LAR06319 [1-3]. Here, we present petrography and new data on the trace element chemistry of LAR12011.
