Petrology and petrogenesis of lunar breccia 12013Sample 12013 is extremely rich in incompatible elements (K, P, U, Th, Pb, Ba, Rb, Zr, Nb, and rare earths) relative to other lunar samples, and it contains abundant granitic material composed of silica minerals and K-feldspar. The present investigation provides detailed petrologic and mineralogic descriptions of the rock and a discussion of its genesis and history. The sample is made up of two lithologies, including a mottled gray and white lithology, and a black lithology. A detailed petrology of the gray breccia is presented, taking into account lithic clasts, mineral clasts, deformation textures in clasts, the matrix, and felsite. A detailed petrology of the black breccia is also provided. Attention is given to a model for the formation of the breccia, an evaluation of the possible genetic relationships between the various components, and some constraints on the nature of the source area.
