Lunar Anorthosites and the Magma Ocean Concept

Lunar Anorthosites and the Magma Ocean Concept. Lunar anorthosites are thought to have crystallized in a global magma system to form the primary lunar crust. Its crystallization can be tracked by assessing the composition of the magma. Anorthosite 62236.

  1. Lunar Anorthosites and the Magma Ocean Concept Lunar anorthosites are thought to have crystallized in a global magma system to form the primary lunar crust. Its crystallization can be tracked by assessing the composition of the magma. Anorthosite 62236 How? Measure concentrations of trace elements in individual minerals. COSMOCHEMISTRY iLLUSTRATED

  2. REE in Plagioclase COSMOCHEMISTRY iLLUSTRATED

  3. Distribution Coefficient CS is the concentration of an element in the solid (mineral). CL is the concentration of an element in the liquid (magma). • Incompatible elements have D << 1 • Compatible elements have D >> 1 COSMOCHEMISTRY iLLUSTRATED Lunar Anorthosite Parent Magma

  4. REE in Parent Magmas COSMOCHEMISTRY iLLUSTRATED
