Among them, analcimes are considered as third in order of importance after clinoptilolites and phillipsites; they are also the least known. This is why this study was chosen. The aim is to determine the physico-chemical (temperature, pressure, nature of interstitial solutions...) and sedimentologic parameters which govern the crystallization of analcimes, and influence their chemical composition. Starting with the principle that certain mineral species which coexist with analcimes form with them in paragenesis, and considering their respective domains of stability, an attempt is made for the definition of the conditions of formation of this zeolite in marine environments.completedOceanographyalterationanalcimecrystal structureDeep Sea Drilling ProjectDSDP Site 216DSDP Site 253DSDP Site 317ADSDP Site 446DSDP Site 485Aframework silicatesigneous rocksIndian OceanIPODLeg 22Leg 26Leg 33Leg 58Leg 65marine sedimentsmetalsmineral compositionoceanographyPacific Oceanparagenesispore waterrare earthssedimentsSEM datasilicatesthesisvolcanic rocksX-ray datazeolitezeolite groupurn:org.iodp:exp:22urnlargerWorkCitationcampaignurn:org.iodp:exp:26urnlargerWorkCitationcampaignurn:org.iodp:exp:33urnlargerWorkCitationcampaignurn:org.iodp:exp:58urnlargerWorkCitationcampaignurn:org.iodp:exp:65urnlargerWorkCitationcampaignurn:org.iodp:exp:22:site:216urnlargerWorkCitationstudyurn:org.iodp:exp:22urnlargerWorkCitationcampaignurn:org.iodp:exp:26:site:253urnlargerWorkCitationstudyurn:org.iodp:exp:26urnlargerWorkCitationcampaignurn:org.iodp:exp:58:site:446urnlargerWorkCitationstudyurn:org.iodp:exp:58urnlargerWorkCitationcampaignFrenchgeoscientificInformation-169.0000147.0000-60.000025.0000Indian Ocean
