CRISP involved the only known erosional end-member of convergent margins within reach of scientific drilling. With a relatively thin sediment cover, fast convergence rate, abundant seismicity, subduction erosion, and change in subducting plate relief along strike, CRISP offered excellent opportunities to learn the causes of earthquake nucleation and rupture propagation. This project complements other deep-fault drilling (San Andreas Fault Observatory at Depth and Nankai Trough Seismogenic Zone Experiment) and investigates the first-order seismogenic processes common to most faults and those unique to erosional margins. The primary goals of Expedition 334 were - Characterization of lithological, physical, and frictional properties of upper plate material; - Estimation of subduction channel thickness and the rate of subsidence caused by subduction erosion; - Characterization of the fluid flow system and thermal structure of the erosive margin; and - Determination of the change in the stress field across the updip limit of the seismogenic zone. In order to accomplish these objectives, coring was conducted at three slope sites (Sites U1378 and U1380 on the middle slope and Site U1379 on the upper slope) and at one site on the Cocos plate (Site U1381). Expedition 334 is also the first step toward deep riser drilling through the aseismic and seismic plate boundary; both slope sites might serve as pilot holes for a potential future riserdrilling project. Sites U1378 and U1379 were first characterized by logging while drilling (LWD) to document in situ physical properties, stratigraphic and structural features, and stress state, in addition to continuous core sampling to the target depth. Cores were taken at both sites to examine slope sediment and the underlying upper plate basement. Coupling LWD data with data from sediment and basement samples provides important information about tectonic, hydrologic, and seismic features along this erosive convergent margin.completedStratigraphyApplied geophysicsalgaebiostratigraphyboreholesCenozoicCentral AmericacoresCosta RicacrustdiatomsearthquakesEast PacificExpedition 334Foraminiferagenesisgeophysical methodsheat flowigneous rocksIntegrated Ocean Drilling ProgramInvertebrataIODP Site U1378IODP Site U1379IODP Site U1380IODP Site U1381lithostratigraphymagnetostratigraphymicrofossilsMiddle America TrenchnannofossilsNeogeneNorth PacificNortheast Pacificoceanic crustPacific OceanpaleomagnetismPlantaeplate tectonicsProtistaQuaternarysedimentary rocksseismic methodssubduction zonesTertiaryvolcanic rocksurn:org.iodp:exp:334urnlargerWorkCitationcampaignurn:org.iodp:exp:334:site:U1378urnlargerWorkCitationstudyurn:org.iodp:exp:334urnlargerWorkCitationcampaignurn:org.iodp:exp:334:site:U1379urnlargerWorkCitationstudyurn:org.iodp:exp:334urnlargerWorkCitationcampaignurn:org.iodp:exp:334:site:U1380urnlargerWorkCitationstudyurn:org.iodp:exp:334urnlargerWorkCitationcampaignurn:org.iodp:exp:344:site:U1380urnlargerWorkCitationstudyurn:org.iodp:exp:344urnlargerWorkCitationcampaignurn:org.iodp:exp:334:site:U1381urnlargerWorkCitationstudyurn:org.iodp:exp:334urnlargerWorkCitationcampaignurn:org.iodp:exp:344:site:U1381urnlargerWorkCitationstudyurn:org.iodp:exp:344urnlargerWorkCitationcampaignEnglishgeoscientificInformation-84.4002-84.02028.25438.4051application/pdfunknownSEDIS Publication Catalogue
