(editor), Henrys, Stuart A. (editor), Antarctica at the close of a millennium; proceedings of the 8th international symposium on Antarctic earth sciences35239-247Although the submergent Kerguelen Plateau (KP), a large igneous province in the Southern Indian Ocean, was initiated after the rifting of India from Antarctica, its construction, fed by the Kerguelen hot spot, has taken place over the past c. 114 m.y. Preliminary shipboard paleontologic and paleomagnetic dates from ODP Leg 183 on marine sediments above igneous basement help constraint the growth history of this feature. The oldest such date is late Albian (105-106 Ma or younger) from Site 1136 on the southern KP, whereas the youngest is early Oligocene (more precisely, 34 Ma) from Sites 1139 and 1140 on the northern KP. Elan Bank provided intermediate ages of late Campanian (c. 75 Ma); however, Site 1138 on the central KP yielded lower Turonian (c. 93.5 Ma) marine sediments (Cenomanian/Turonian boundary "black shales") above upper Albian-lowest Cenomanian (c. 102-96 Ma) non-marine (fluvial) claystones, sandstones, and conglomerates. This latter date (from shore-based palynology) diminishes considerably the previously inferred age difference between the southern and central KP and, in so doing, tends to blur the geophysical distinction between these two domains.completedStratigraphyalgaeCenozoiccoresElan BankForaminiferahot spotsInvertebrataKerguelen Plateaularge igneous provincesLeg 183marine sedimentsmicrofossilsnannofossilsOcean Drilling ProgramODP Site 1136ODP Site 1138ODP Site 1139ODP Site 1140paleomagnetismpalynomorphsPhanerozoicplanktonic taxaPlantaeplate tectonicsProtistasedimentsSouthern Oceanurn:org.iodp:exp:183urnlargerWorkCitationcampaignurn:org.iodp:exp:183:site:1136urnlargerWorkCitationstudyurn:org.iodp:exp:183urnlargerWorkCitationcampaignurn:org.iodp:exp:183:site:1138urnlargerWorkCitationstudyurn:org.iodp:exp:183urnlargerWorkCitationcampaignurn:org.iodp:exp:183:site:1139urnlargerWorkCitationstudyurn:org.iodp:exp:183urnlargerWorkCitationcampaignurn:org.iodp:exp:183:site:1140urnlargerWorkCitationstudyurn:org.iodp:exp:183urnlargerWorkCitationcampaignEnglishgeoscientificInformation68.293084.5006-59.3906-46.1536
