This contribution presents a graphical downhole log for core recovered from Integrated Ocean Drilling Program (IODP) Hole U1309D made during postcruise study at the Bremen Core Repository. More than 3500 observations of the rock composition and structural relations are presented, including igneous composition, texture and grain size variations, layering and intrusive contact orientation, and younger/older intrusive relations, together with observations of fault/shear zone thickness and orientation and alteration mineral assemblages. In addition, remanence components for 523 new specimens are shown along with shipboard magnetic susceptibility and 18 Pb/U zircon ages from evolved Fe-Ti oxide gabbro and felsic dikes from Hole U1309D. This compilation is a resource for researchers interested in the composition, construction, and deformation of slow-spreading gabbroic crust, in particular the scale/thickness of intrusive bodies and the order of intrusion.
