Scanned drill core images showing the contact between hemipelagic sediment and the sulphide body at Hole C9026A. The T-layer, composed of pyrite + barite + marcasite + sphalerite + galena, is 2 cm thick and is interpreted as a cap layer restricting hydrothermal fluid to lateral flow, controlling subseafloor sulphide mineralisation and hydrothermal alteration. Anh anhydrite, Brt barite, Chl chlorite, Gn galena, Ill illite, Kln kaolinite, Mnt montmorillonite, Mrc marcasite, Py pyrite, Qtz quartz; Sp, sphalerite.
