Special Issue Information

Dear Colleagues,

The basaltic rocks from the oldest oceanic crust in today’s oceans can only provide evidence of the geological evolution of oceanic crust younger than ca. 200 Ma; however, such igneous rocks, found, for instance, in ophiolitic complexes and in many paleo-sutures/orogens, can provide key clues for the evolution of oceanic crust (e.g., Tethys oceans) or for the multiple assembly and dispersal history of supercontinents during several billion years. Basalts, used as a ‘probe’ for igneous processes, play a key role in understanding regional and global tectonic evolution, deciphering deep magmatic processes, developing global tectonic theories (e.g., plate tectonics and mantle plumes), and exploring mineral resources. Over the past decade, there have been advances in global ocean investigations performed by some international drilling programs (e.g., IODP, ICDP, InterRidge, etc.) and many other cruises and field sampling campaigns in numerous paleo-sutures/orogens, and more volcanic rock samples have been collected from various oceanic crusts and paleo-sutures in land. This Special Issue welcomes manuscripts that present research progress in any of these aspects, including the age and mineralogical, petrological, and geochemical compositions of volcanic rocks (basalts and more differentiated rocks) from key tectonic settings frommid-oceanic ridges via intraplate setting (LIP and seamounts/guyots) to subduction zones.

The Altyn Tagh Fault plays a critical role in understanding the tectonic evolution of the northern margin of the Tibetan Plateau. However, considerable debate persists regarding its activity and deformation history. This study investigates volcanic rocks from the Beidayao-Jianquanzi-Hanxia-Hongliuxia area in the eastern segment of the fault. By employing zircon U-Pb dating, whole-rock geochemistry, and Sr-Nd isotope analysis, we aim to elucidate their petrogenesis and tectonic setting, thereby providing new insights into the crustal evolution of the eastern Altyn Tagh Fault. Zircon U-Pb dating of the Hongliuxia rhyolite yields a weighted mean 206Pb/238U age of 106.6 ± 0.6 Ma, indicating an Early Cretaceous eruption. Geochemically, the western part of the study area (Beidayao and Jianquanzi) is dominated by basalts that exhibit significant enrichment in large ion lithophile elements and light rare earth elements, together with high Nb concentrations (>20 ppm), as well as high Nb/La (0.64–1.12) and Nb/U (29.8–35.42) ratios, consistent with the characteristics of high-Nb basalt. In contrast, the eastern area (Hanxia and Hongliuxia) is characterized by andesitic rocks that display typical continental arc affinities, marked by enrichment in Th, U, and Pb and depletion in Nb, Ta, and Ti. Isotopically, the basalts show initial 87Sr/86Sr ratios of 0.706–0.707 and εNd (t) values ranging from −3.2 to 0.8, whereas the andesites possess more radiogenic Sr isotopic compositions, with (87Sr/86Sr)i ratios of 0.710–0.717, and more negative εNd (t) values from −11.4 to −1.5, suggesting derivation from an enriched mantle source. Integrating geochemical data with regional geological records, we propose that the eastern part of the Altyn Fault experienced a significant intracontinental extensional setting during the Early Cretaceous, where asthenospheric mantle upwelling played a key role in the generation of the volcanic rocks. This study provides key petrological and geochemical constraints on Early Cretaceous deformation and activity along the Altyn Tagh Fault, and also offers a valuable reference for understanding the evolution of similar fault systems.
