TL;DR: In this paper, the authors presented new data relating to the tectonic evolution of the Zhonggang ocean island, within the Mesozoic Banggongco-Nujiang suture zone of northern Tibet, and discussed the implications of these data for the evolution of this region.
Abstract: This study presents new data relating to the tectonic evolution of the Zhonggang ocean island, within the Mesozoic Banggongco–Nujiang suture zone of northern Tibet, and discusses the implications of these data for the evolution of this region. Thirteen basalt and ten gabbro samples were collected from a sampling transect through this area; these samples have light rare earth element (LREE)-enriched chondrite-normalized REE patterns, and are enriched in highly incompatible elements, yielding primitive-mantle-normalized trace-element variation patterns that are similar to ocean island basalts (OIB). A gabbro dike intruded into basalt of the Zhonggang ocean island and was overlain by basaltic conglomerate, suggesting that this dike was formed after the basalt, but before the basaltic conglomerate. The gabbro dike yields an LA–ICP–MS zircon U–Pb age of 116.2 ± 4.1 Ma, indicating the timing of formation of the Zhonggang ocean island, and suggesting in turn that the Banggongco–Nujiang Neo-Tethys Ocean remained ...

TL;DR: In this paper, the high magnesian series basalts (HMSB) and the low Magnesian Series basalts were derived from similarly depleted source regions and it was argued that the main petrogenetic difference between these three volcanic suites was the degree of partial melting from which they were derived.

TL;DR: In this article, the authors suggest that the incorporation of high-Cl phases such as saline brine or Cl-rich minerals (halite or iron-hydroxychlorides) can explain the range and magnitude of Cl contents in Loihi glasses, as well as the variance in the ratios of Cl to other incompatible elements.

TL;DR: In this article, the consequences of melting and melt transport for stable trace element geochemistry in open systems are investigated, showing that trace elements are sensitive to mantle dynamics and can readily distinguish between different end-member flow fields.

TL;DR: The Sabatini Volcanic District (SVD) is a large volcanic field characterised by the lack of any major volcanic center as discussed by the authors, and all the volcanic rocks belong to the Roman-type ultrapotassic series (HKS).
