Reconnaissance initial Nd and Sr isotope data for the older rocks (similar to 820-740 Ma) reaffirms previous estimates that early crustal evolution in this part of the shield involved some crustal contamination by pre-ANS material. Prominent isotope provinciality is displayed by post-collisional calc-alkaline and alkaline igneous rocks of similar to 635-570 Ma across a NW-SE transect across basement of the Sinai Peninsula (Egypt) and southern Israel. Silicic rocks of the NW-region are characterized by lower epsilon Nd(T)-epsilon Hf(T) and higher Sr(i) and delta(18)O compared with rocks of the SE-region, and the transition between the regions is gradual. Within each region isotope ratios are independent of the extent of magma fractionation, and zircon cores and rims yield similar delta(18)O values. Comparison with southern segments of the ANS shows that the source for most similar to 635-570 Ma rocks can be modeled as the isotopically aged lower-intermediate crust in the ANS core (SE-region) and its northern, more contaminated ANS margins (NW-region). Nevertheless, Nd-Sr isotope enrichment of the lithospheric mantle is indicated by some basic magmas of the NW-region displaying the most enriched Nd-Sr isotope compositions. Comparison of Nd and Hf depleted mantle model ages for rocks of the SE-region may indicate that crustal formation events in the ANS geographical core took place at 1.1-1.2 Ga and were followed by crustal differentiation starting at similar to 0.9 Ga."],["dc.identifier.doi","10.1007/s00410-009-0472-8"],["dc.identifier.isi","000279585700002"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/6739"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/19294"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.notes.submitter","Najko"],["dc.relation.issn","0010-7999"],["dc.relation.orgunit","Fakultät für Geowissenschaften und Geographie"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Nd-Sr-Hf-O isotope provinciality in the northernmost Arabian-Nubian Shield: implications for crustal evolution"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Combined with literature data, LMA have low epsilon(Nd)(t) (-27.8 to -14.7) and Pb-206/Pb-204(i) (15.69-17.16) and low to moderately high Sr-87/Sr-86(i) (0.7066 to 0.7087) ratios. Normal granitoids yield isotope ratios similar to adakitic rocks, except a few with Sr-87/Sr-86 (i) up to 0.7105. Dabie LMA define a linear trend parallel to the North Hemisphere Reference Line (NHRL) in a Pb-208/Pb-204(i)- Pb-206/Pb-204(i) diagram. For a given Pb-206/Pb-204(i), the Pb-208/Pb-204(i) or Delta 8/4 (152-217) of Dabie LMA are close to the majority of UHP gneisses and the Neoproterozoic mafic rocks from the northern margin of the South China Block (SCB), but significantly higher than adakitic rocks from the North China Block (Delta 8/4<150). Considering the commonly present Neoproterozoic inherited zircons, we suggest that the LMA in the Dabie orogen are derived from a thickened LCC that could be dominantly composed of ancient SCB lower crust. The Sr-Nd-Pb isotopic composition of LMA are similar to those of Post-Collisional Mafic Igneous rocks (PCMI) from the Dabie orogen, but different to exhumed UHP rocks. The Sr-Nd-Pb isotopic system of the mantle source of the PCMI could be enriched in components dominantly from delaminated LCC of the Dabie orogen instead of deeply subducted continental crust, which is in contrast to O- and C-isotope data by [Zhao, Z.F., Zheng, Y.F., Wei, C.S., Wu, Y.B., Chen, F.K, and Jahn, B.M., 2005.

The detrital zircon age population is bimodal, with concordia ages of 1029 +/- 7 Ma and 1110 +/- 8 Ma. The whole-rock epsilon(Nd) (t = 1.0 Ga) value of +2 is significantly lower than found for juvenile Neoproterozoic rocks in the region. Thus, the Sa'al schist is interpreted to represent Kibaran (Grenville) age crust incorporated into the northernmost ANS. The delta(18)O (zircon) values (6.1%-9.4%) imply that supracrustal recycling was involved in the formation of this ca. 1.0-1.1 Ga crust. A compilation of reported xenocrystic and detrital pre-ANS zircons and the variability of Nd, Sr, Pb, and O isotopic compositions within the shield suggests that its northernmost and eastern margins were more strongly contaminated by older crust ca. 0.9-3.0 Ga old. The distribution of 0.9-1.1 Ga xenocrystic and detrital zircons mainly in the east and north of the ANS suggests that such crust characterized parts of the northeastern margin of western Gondwana prior to ANS formation, and that 0.9-1.1 Ga old zircons detected in lower Paleozoic sandstone cover may have a proximal provenance."],["dc.identifier.doi","10.1130/G30206A.1"],["dc.identifier.isi","000270386900010"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/56233"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Geological Soc Amer, Inc"],["dc.relation.issn","0091-7613"],["dc.title","Contribution of pre Pan-African crust to formation of the Arabian Nubian Shield: New secondary ionization mass spectrometry U-Pb and O studies of zircon"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Within the Fennoscandian Shield, the first cycle is correlated with the 1.95-1.8 Ga Svecofennian domain and the second is correlated with the 1.85-1.65 Ga Transscandinavian Igneous Belt (TIB). Affiliation of Palaeoproterozoic granitoids to syenitoids (similar to 1.8 Ga) in a transitional zone between the Svecofennian domain to the north and the TIB to the south in the Vastervik area in southeast Sweden, is highly debated. In this study, the Vastervik granitoids to syenitoids have been studied for major and trace element, whole-rock Sm-Nd and U-Pb single zircon isotopic compositions. Field observations, petrography and geochemical composition allow discrimination into five groups ranging from tonalitic to syenogranitic compositions. Geochemical signatures indicate magnesian, metaluminous cordilleran character for three of them, whereas the two most differentiated groups show a transition into ferroan, peraluminous granites with postorogenic or A-type characters. The former three groups may be correlated with the TIB-1 suite at 1.81-1.77 Ga. The older of the A-type groups may be correlated with the TIB-0 suite that intruded at 1.87-1.84 Ga whereas the younger group possibly is related to the so-called granite-pegmatite suite.

The Vastervik area is located between these two major tectonic domains and as such has received much attention. Granitoids of the Vastervik area were recently re-grouped and classified within the context of this larger regional tectonic model, but a discrepancy between previous relative age estimations and the few available granitoid age determinations was noted. To address this issue, we have dated 13 granitoid samples using a high spatial resolution secondary ion mass spectrometry (SIMS) U-Pb technique. Our new results constrain the intrusion of the majority of granitoids to 1819-1795 Ma, thus placing them into the TIB-1 period. This age range also encompasses our new ages from the central granodiorite belt and the Oro-Hamno pluton, demonstrating a previous overestimation of older granitoid generations in the Vastervik area. Nonetheless, it is shown that Askersund/TIB-0 magmatism, represented by an augen gneiss sample dated to 1846 Ma, is unambiguously present as far south as the Vastervik region. The anatectically generated leucogranites reveal TIB-1 ages and, as expected, older inherited zircon derived from the parental metasedimentary Vastervik formation. By simple Sr-Nd isotope modeling it is further possible to deduce that most TIB-1 granitoids follow a simple (assimilation-) fractional crystallization petrogenetic trend. The youngest granitoid generation was produced through low-pressure fluid-absent crustal melting. In conclusion, granitoids of the Vastervik area fit well into the proposed model for south-westward migration of a subduction zone system active in the Svecofennian domain and represent a new tectonic cycle. It is therefore possible to link the Svecofennian domain and the Transscandinavian Igneous Belt within a single evolutionary scenario explaining the observed granitoid petrology, geochemistry and geochronology. The study area is located at the edge of a particularly long-lived active continental margin that started to operate during the supercontinent Columbia at ca. 1.8 Ga and the presented model explains how this margin initiated at its eastern end.
