Abstract Intraplate volcanism initiated shortly after the cessation of Cenozoic seafloor spreading in South China Sea (SCS) region, but full extent its influence on Indochina block has not been well constrained. Here we present major and trace element data Sr-Nd-Pb-Hf isotope ratios late basaltic lavas from Khorat plateau some volcanic centers Paleozoic Sukhothai arc terrane Thailand. These rocks are mainly trachybasalts trachyandesites. Trace patterns isotopic compositions show that these...
Abstract Molybdenum (Mo) isotope ratios provide a potential means of tracing material recycling involved in subduction zone processes. However, the geochemical behavior Mo subducted oceanic crust remains enigmatic. We analyzed arc and back-arc basin lavas from Mariana (western Pacific Ocean), combining newly obtained element Sr-Nd-Pb-Li data to investigate processes involving Mo. The (δ98/95MoNIST3134; U.S. National Institute Standards Technology [NIST] standard) volcanic rocks showed clear...
Abstract Deciphering the Earth's deep carbon cycle, from mantle plumes to mid‐ocean ridges, remains incompletely understood. In this study, we analyze magnesium isotope composition of basalts collected South Mid‐Atlantic Ridge (SMAR), which have been influenced by off‐axis Saint Helena plume originating core‐mantle boundary. The SMAR falls within a similar range (−0.22 −0.32‰; average −0.25‰ ± 0.03‰) that known global oceanic basalts. However, mixing calculations suggest lighter in is due...
Hydrothermal activity on the modern seafloor varies depending tectonic setting. In particular, neovolcanic zones (NVZs) along mid-ocean ridges, where magmatism is intense, generally host high-temperature hydrothermal activities. These activities NVZs can promote development of many polymetallic sulfide deposits. Currently, and accumulations have been discovered major ridges worldwide, but relatively few found in Southern Mid-Atlantic Ridge (SMAR), which limits our understanding...
Biogeochemical mineralization is increasingly recognized as a significant factor in the formation of submarine hydrothermal sulfide deposits. While several mechanisms by which organisms may facilitate metal deposition have been documented many seafloor deposits, potential involvement biogenic processes deposits southern Mid-Atlantic Ridge (SMAR) has largely overlooked until now. In this study, we investigate chimney sample from volcanic-hosted Tongguan field on SMAR and present lines...
In modern seafloor hydrothermal mineralization systems, subseafloor deposits are crucial alongside massive sulfides, consisting mainly of stockwork at the periphery and semi-massive sulfides central ore bodies. These two types exhibit contrasting mineralogical elemental compositions, difference between their formation processes unclear due to sampling challenges. The mafic-hosted Taiji-2 field, located on Southern Mid-Atlantic Ridge, presents pyrite-enriched seafloor, providing a good...
Abstract The West Philippine Basin is not only a back-arc basin resulting from the subduction of paleo-plates, but it has also undergone modification due to intraplate processes. However, interaction between processes and spreading remains unclear. In this study, we present geochemical compositions basaltic lavas various tectonic sites in Basin. Lavas Benham Rise its adjacent seamount, as well basement crust samples Basin, are similar oceanic island basalts mid-oceanic ridge basalts,...
ABSTRACT Our general understanding of mantle composition and dynamics mainly comes from the lavas oceanic intraplate volcanoes. They are generally accepted to originate deep, relatively stationary plumes. Many groups seamounts comprising West Pacific Seamount Province (WPSP), however, do not form long-lived, narrow continuous chains volcanoes with clear age progression; thus, their origin does seem fit this model. Here we show a wide compositional spectrum Pako guyot within Magellan seamount...
The South Mid-Atlantic Ridge (SMAR) 19°S segment, approximately located along the line of Saint Helena volcanic chain (created by mantle plume), is an ideal place to investigate issue whether ridge-hotpot interaction process affected whole MAR. In this study, we present major and trace elemental compositions Sr-Nd-Pb isotopic ratios twenty fresh lava samples concentrated in a relatively small area SMAR segment. Major oxides show that all are tholeiite. Low contents compatible elements (e.g.,...
