New Group Paper: Using Lunar Granulites to Constrain Re-Equilibration Timescales of Contact Thermal Metamorphism on the Moon

This gallery contains 2 photos.

In our new paper, we explore the conditions within the Moon’s crust that result in the formation of granulites. Granulites are a rock type that formed from high temperature recrystallisation of existing highland rocks (see our previous post reviewing the … Continue reading

New Group Paper: Identifying primitive noble gas components in lunar ferroan anorthosites

This gallery contains 1 photo.

The Earth-Moon system is thought to have formed in a volatile-poor environment relative to the outer Solar System. Despite this, measurable quantities of volatile elements have been reported in lunar samples.  These volatiles do not necessarily represent primordial (i.e., original) … Continue reading

New Group Paper: Evidence of chemical heterogeneity within Lunar anorthosite parental magmas

This gallery contains 1 photo.

The Moon’s crust is very old. Formed over 4.3 billion years ago, it represents the primary lunar crust. Made up of a rocks called anorthosite (> 95 modal % Ca-rich plagioclase; see below), it makes up the light-grey areas seen … Continue reading
