Abstract

The Apollo mare-basalts represent the largest and most pristine collection of lunar basaltic material on Earth. A thorough assessment of their petrological and geochemical characteristics provides key information on the evolutionary history of the Earth-Moon system. The aim of our research is to carry out systematic studies involving mineralogy, petrology and geochemistry of a suite of mare basalts from the Apollo 11, 12, 14, 15 and 17 sites. With the aid of in situ U-Pb dating of phosphates in the Apollo basalts, the samples are being grouped within the existing lunar classification scheme(s) with the aim of gaining a more precise chronology of basalt extrusions at these locations.
