Nomenclature of each specimen follows the rule described in Annex 1.1. Images are grouped following the original file names used during this work: thus, the number of the “GEO” groups (1A, 2, 3, 4, etc.) corresponds to digits 5 and 6, as defined in Annex 1.1. Specimens used in this part of the study originate from the following boreholes: DSDP 80-548A, ODP 196-998A, DSDP 41-366A, ODP 121-758A, ODP 138-850B, ODP 130-806C, ODP 130-806B, ODP 138-848B, ODP 115-707A, DSDP 33-317B, DSDP 74-526A, ODP 121-754A.
