The three‐dimensional density model that reproduces the gravity field is a continental‐scale representation of density structure to 410 km depth that characterizes the mantle and crust of the oceanic Nazca plate, subducted slab and continental margin with a minimum number of bodies. We predefined the density of each body after studying the dependency of density on composition of crustal and mantle materials and pressure‐temperature conditions appropriate for the Andean setting. A database of independent geophysical information constrains the geometry of the top of the subducted slab, locally the Moho of the oceanic and continental crusts and, indirectly, the lithosphere‐asthenosphere boundary underneath the continental plate. Other boundaries, notably the intracrustal density discontinuity separating upper from lower crust below the continent, were not constrained and their geometry is the result of fitting the observed and calculated Bouguer anomaly during forward modeling. This contribution presents the model to the Andean geoscientific community and contains some tools, like a sensitivity analysis, that helps potential users of the model to interpret its results. We describe and discuss some of these results in order to illustrate the application of the model to the study of a wide range of phenomena (e.g., modification of oceanic plate structure by hot spots, shape of the subducted slab, thermal structure of the continental lithosphere, compensation mechanism and formation of orogenic relieve, causes of Andean segmentation).</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380011144094783106","@type":"Researcher","foaf:name":[{"@value":"Andrés Tassara"}],"jpcoar:affiliationName":[{"@value":"Institut für Geologische Wissenschaften Freie Universität Berlin  Berlin Germany"}]},{"@id":"https://cir.nii.ac.jp/crid/1380579818375800576","@type":"Researcher","foaf:name":[{"@value":"Hans‐Jürgen Götze"}],"jpcoar:affiliationName":[{"@value":"Institut für Geowissenshaften Christian‐Albrechts‐Universität zu Kiel  Kiel Germany"}]},{"@id":"https://cir.nii.ac.jp/crid/1380011144094783104","@type":"Researcher","foaf:name":[{"@value":"Sabine Schmidt"}],"jpcoar:affiliationName":[{"@value":"Institut für Geowissenshaften Christian‐Albrechts‐Universität zu Kiel  Kiel Germany"}]},{"@id":"https://cir.nii.ac.jp/crid/1380011144094783232","@type":"Researcher","foaf:name":[{"@value":"Ron Hackney"}],"jpcoar:affiliationName":[{"@value":"Institut für Geowissenshaften Christian‐Albrechts‐Universität zu Kiel  Kiel Germany"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"01480227"}],"prism:publicationName":[{"@value":"Journal of Geophysical Research: Solid Earth"}],"dc:publisher":[{"@value":"American Geophysical Union (AGU)"}],"prism:publicationDate":"2006-09","prism:volume":"111","prism:number":"B9","prism:startingPage":"b09404"},"reviewed":"false","dc:rights":["http://onlinelibrary.wiley.com/termsAndConditions#vor"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1029%2F2005JB003976"},{"@id":"https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/2005JB003976"}],"createdAt":"2006-09-25","modifiedAt":"2023-10-12","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360004235825644032","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Spatiotemporal variations of Jurassic–Cretaceous magmatism in eastern<scp>A</scp>sia (Tan‐Lu Fault to<scp>SW J</scp>apan): evidence for flat‐slab subduction and slab rollback"}]},{"@id":"https://cir.nii.ac.jp/crid/1360025431093201664","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Along-strike forearc and subducted upper slab structure beneath north Chile: Slow slip implications"}]},{"@id":"https://cir.nii.ac.jp/crid/1360283690913952640","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Exploring the structural controls on helium, nitrogen and carbon isotope signatures in hydrothermal fluids along an intra-arc fault system"}]},{"@id":"https://cir.nii.ac.jp/crid/2050025942153543296","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"A possible mechanism for spontaneous cyclic back-arc spreading"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1029/2005jb003976"},{"@type":"CROSSREF","@value":"10.1111/ter.12051_references_DOI_4mLjoruVLWtraJilGqdHYaP2YG0"},{"@type":"CROSSREF","@value":"10.1016/j.jsames.2024.105064_references_DOI_4mLjoruVLWtraJilGqdHYaP2YG0"},{"@type":"CROSSREF","@value":"10.1016/j.gca.2016.04.031_references_DOI_4mLjoruVLWtraJilGqdHYaP2YG0"},{"@type":"CROSSREF","@value":"10.1186/s40645-022-00486-3_references_DOI_4mLjoruVLWtraJilGqdHYaP2YG0"}]}
