Comment on ‘The magmatic architecture and evolution of the Chang’e-5 lunar basalts’ Penny E. Wieser1, Christy Till2, Adam Kent3, Matthew Gleeson1

Abstract

Luo et al.1 present exciting new data on lunar basalt samples erupted at ~2 Ga, and brought to Earth by the Chang’e-5 (CE-5) mission. These samples offer important new opportunities to understand lunar magmatic systems. Luo et al.1 use Clinopyroxene-Liquid (Cpx-Liq) thermobarometry and pMELTS modelling of mineral compositions to determine the pressures (P) and temperatures (T) of magma storage on the moon. However, in this comment we discus the large analytical errors associated with their measurements, and the implications for their intepretation.
