Olivine unlocks the secrets of the Moon’s interior | Science & Technology

New partitioning coefficients of first-transition row elements, Ga and Ge between olivine and silicate melt have been reported. New high-temperature experiments have investigated the effects of oxygen fugacity and iron content on these partition coefficients. This newly compiled dataset offers insights into interpreting trace elements found in olivine phenocrysts within lunar basalts, shedding light on the deep interior composition of the Moon.

Olivine is the earliest mineral to crystallize from basaltic magma, and accurate knowledge of olivine/melt partition coefficients (DOlmelt ) for first-transition row elements (FTREs) Ga and Ge, is required in quantitative modeling of petrogenetic processes in planetary basalts. Numerous experimental studies have focused on this topic, but most investigations concentrated on minor elements found in olivine, and the oxygen fugacities (fO2) in many of these experiments were commonly designed to be similar to those found in Earth’s mantle. However, for applications involving the formation of basalt on other rocky planetary bodies including the Moon, Mars, and asteroids, oxygen fugacities during basalt formation can range widely from 2 log units below the iron-wüstite buffer (herein referred to as IW-2) to IW+6. In addition, lunar basalts are generally iron-rich compared to terrestrial basalts.

To assess the effects of oxygen fugacity and iron content on partition coefficients of FTREs, Ga and Ge, Dr. Jiejun Jing (a JSPS postdoctoral fellow in Ehime University) conducted a series of high-temperature experiments (around IW-2 to IW+5.5) at 1 atm using a gas-mixing furnace with the cooperation of colleagues in Ehime University, and in other universities in the Netherlands, China and Germany. The results show that most DOlmelt show no sensitivity to bulk system iron contents, but DOlmeltCr is significantly higher in our experiments compared to DOlmeltCr derived from olivine-melt inclusion pairs in lunar samples with much…
