| 1 | A new method of discriminating different types of post-Archean ophiolitic basalts and their tectonic significance using Th-Nb and Ce-Dy-Yb systematics显示文摘In this paper,a new discrimination diagram using absolute measures of Th and Nb is applied to postArchean ophiolites to best discriminate a large number of different ophiolitic basalts.This diagram was obtained using>2000 known ophiolitic basalts and was tested using w560 modern rocks from known tectonic settings.Ten different basaltic varieties from worldwide ophiolitic complexes have been examined.They include two basaltic types that have never been considered before,which are:(1)medium-Ti basalts(MTB)generated at nascent forearc settings;(2)a type of mid-ocean ridge basalts showing garnet signature(G-MORB)that characterizes Alpine-type(i.e.,non volcanic)rifted margins and ocean-continent transition zones(OCTZ).In the Th-Nb diagram,basalts generated in oceanic subductionunrelated settings,rifted margins,and OCTZ can be distinguished from subduction-related basalts with a misclassi fi cation rate<1%.This diagram highlights the chemical variation of oceanic,rifted margin,and OCTZ basalts from depleted compositions to progressively more enriched compositions re fl ecting,in turn,the variance of source composition and degree of melting within the MORB-OIB array.It also highlights the chemical contributions of enriched(OIB-type)components to mantle sources.Enrichment of Th relative to Nb is particularly effective for highlighting crustal input via subduction or crustal contamination.Basalts formed at continental margin arcs and island arc with a complex polygenetic crust can be distinguished from those generated in intra-oceanic arcs in supra-subduction zones(SSZ)with a misclassi fi cation rate<1%.Within the SSZ group,two sub-settings can be recognized with a misclassi fi cation rate<0.5%.They are:(1)SSZ in fl uenced by chemical contribution from subductionderived components(forearc and intra-arc sub-settings)characterized by island arc tholeiitic(IAT)and boninitic basalts;(2)SSZ with no contribution from subduction-derived components(nascent forearc sub-settings)characterized by MTBs and depleted-MORBs.Two additional discrimination diagrams are proposed:(1)a Dy-Yb diagram is used for discriminating boninite and IAT basalts;(2)a Ce/Yb-Dy/Yb diagram is used for discriminating G-MORBs and normal MORBs.The proposed method may effectively assist in recovering the tectonic af fi nity of ancient ophiolites,which is fundamental for establishing the geodynamic evolution of ancient oceanic and continental domains,as well as orogenic belts. | Emilio Saccani | 2015 | Geoscience Frontiers2015，6，4： | 34 |
| 2 | Cretaceous tectonic evolution of the Neo-Tethys in Central Iran:Evidence from petrology and age of the Nain-Ashin ophiolitic basalts显示文摘The Nain and Ashin ophiolites consist of Mesozoic melange units that were emplaced in the Late Cretaceous onto the continental basement of the Central-East Iran microcontinent(CEIM).They largely consist of serpentinized peridotites slices;nonetheless,minor tectonic slices of sheeted dykes and pillow lavas-locally stratigraphically associated with radiolarian cherts-can be found in these ophiolitic melanges.Based on their whole rock geochemistry and mineral chemistry,these rocks can be divided into two geochemical groups.The sheeted dykes and most of the pillow lavas show island arc tholeiitic(IAT)affinity,whereas a few pillow lavas from the Nain ophiolites show calc-alkaline(CA)affinity.Petrogenetic modeling based on trace elements composition indicates that both IAT and CA rocks derived from partial melting of depleted mantle sources that underwent enrichment in subduction-derived components prior to melting.Petrogenetic modeling shows that these components were represented by pure aqueous fluids,or sediment melts,or a combination of both,suggesting that the studied rocks were formed in an arc-forearc tectonic setting.Our new biostratigraphic data indicate this arc-forearc setting was active in the Early Cretaceous.Previous tectonic interpretations suggested that the Nain ophiolites formed,in a Late Cretaceous backarc basin located in the south of the CEIM(the so-called Nain-Baft basin).However,recent studies showed that the CEIM underwent a counter-clockwise rotation in the Cenozoic,which displaced the Nain and Ashin ophiolites in their present day position from an original northeastward location.This evidence combined with our new data and a comparison of the chemical features of volcanic rocks from different ophiolites around the CEIM allow us to suggest that the Nain-Ashin volcanic rocks and dykes were formed in a volcanic arc that developed on the northern margin of the CEIM during the Early Cretaceous in association with the subduction,below the CEIM,of a Neo-Tethys oceanic branch that was existing between the CEIM and the southern margin of Eurasia.As a major conclusion of this paper,a new geodynamic model for the Cretaceous evolution of the CEIM and surrounding Neo-Tethyan oceanic basins is proposed. | Tahmineh Pirnia Emilio Saccani Ghodrat Torabi Marco Chiari Spela Gorican Edoardo Barbero | 2020 | Geoscience Frontiers2020，11，1： | 2 |
