Abstract The Lantian formation, located in eastern South China block (SCB), forms the lower sequence of the Ediacaran period, at the transition from Proterozoic to Paleozoic. The fossils of Lantian formation have been proposed to predate the Avalon biota (about 579∼565 Ma), the earliest known fossil assemblages with complex morphologies, based largely on stratigraphy. Mineral chemistry and in-situ U–Pb dating of monazites, xenotimes, and zircons from the black shale in fossil-rich zone are studi...

Abstract This study reports zirconium-in-rutile thermometry data from the Himalayan ultrahigh-pressure eclogites and their retrogressed counterparts. The Zr contents of three textural varieties of rutile i.e. matrix rutile, inclusion phase, and overgrown by ilmenite/titanite from coesite-bearing eclogites, slightly retrogressed eclogites, highly retrogressed eclogites, and amphibolites were analyzed for Zr contents using the electron probe micro-analyser. Majority of the rutile grains exhibited ...

Abstract Glass ceramics have demonstrated excellent millimeter-wave dielectric properties for low-temperature-co-fired-ceramic (LTCC) devices applied in the 5G communication. This study highlights silver (Ag)-diffusion mechanism and millimeter-wave dielectric properties of CaO-MgO-SiO2 glass ceramics co-fired with Ag electrode near nucleation temperatures. Ag diffusion and elemental inter-diffusion occur during the endothermic-exothermic process near nucleation temperatures (~820 °C), where Ag d...

We present integrated in-situ zircon U-Pb and Hf isotope, with whole-rock Sr-Nd isotope and geochemical data for plutonic rocks of the Lohit Plutonic Complex (LPC) of eastern Himalayan in order to understand the age distribution and petrogenetic-tectonic evolution of the Transhimalayan batholiths in the eastern Himalaya, The plutonic rocks are gabbro, diorite and quartz-diorite in composition, have calc-alkaline signatures with metaluminous character and have an affinity with Gangdese I-type gra...

The Japanese eel Anguilla japonica is an important aquaculture fish species in the East Asian countries of Japan, China, Korea, and Taiwan. All glass eel fry are captured from the wild and understanding the recruitment patterns of the glass eel is important. The larvae of A. japonica are passively transported to the East Asian Continental Shelf by the North Equatorial Current, the Kuroshio, the Kuroshio intrusion currents, and coastal currents. In each location, recruitment time is diverse: It i...

Glass beads and beadmaking waste have been excavated at the Iron Age site of Jiuxianglan (ca. third century BC–eighth century AD) in southeastern Taiwan. It was suggested that this site may be a production and exchange centre of glass beads in Iron Age Taiwan. This paper presents the analysis of 44 samples, to explore the relationship between glass beads and waste and the nature of bead production at Jiuxianglan. The analysis combines data on style, chemical composition, microstructure and distr...
