  abstract = {{W}e examine the early geological history of the southern {K}erguelen {P}lateau ({I}ndian {O}cean) using ocean bottom seismometer (({ORS}), multichannel seismic ({MCS}), and {O}cean {D}rilling {P}rogram data. {V}elocity-depth models in the sedimentary {R}aggatt {B}asin are constrained by near-range {OBS} data (refractions and reflections, including multiples and converted shear waves) and migrated {MCS} data. {T}he models elucidate the significance of {L}ower {C}retaceous lava flows, {A}lbian to {C}oniacian/{S}antonian terrestrial and terrigenous sediment, and {M}aastrichtian and {P}aleocene seismic sequences. {T}he {A}lbian/{A}ptian basaltic basement complex consists of an upper and a lower series. {T}he upper series is characterized by average {V}ps of 4.6-4.7 km/s, an upward increase of intercalated terrestrial sediment and altered flowtops, and a concomitant decrease in flow thickness ; the lower series is marked by average {V}ps of 5.3-5.5 km/s, and contains thicker flows and less sediment. {A} volcanic center in the {R}aggatt {B}asin shows relatively low {V}ps (3.7-3.9 km/s for the upper series, 4.7-4.9 km/s for the lower series), and dipping reflections on the {R}aggatt {B}asin's flanks are also recorded as refractions. {T}errestrial and terrigenous sediment of the {R}aggatt {B}asin, immediately overlying basement, is characterized by a seismic low-velocity layer with {V}ps ranging from 2.2-2.9 km/s and a thickness of greater than 1100 m in the central basin. {N}earby source regions (e.g. {B}anzare {B}ank and other elevated areas south of the basin) account for a terrestrial and terrigenous sediment volume of approximately 12,500 km3, deposited over approximately 20 m.y. {T}he depocenter of the {R}aggatt {B}asin began shifting in {S}antonian to early {M}aastrichtian time, and concluded by early late {P}aleocene time.
