The breccia — broken fragment of minerals cemented together — is now believed to be formed from impact-generated welding, cementing and agglutinating of lunar regolith and breccia.
The material closely resembles lunar impact melt breccia samples returned by NASA’s Apollo missions.
In particular, similarities with the Apollo samples designated 15466 and 70019 are noted, a comparison made earlier by lunar scientist Professor Clive Neal at the University of Notre Dame.
Sample 70019, collected by astronaut and trained geologist Harrison ‘Jack’ Schmitt, is dark fragments of minerals cemented together and black, shiny glass.
