We present new laser ablation ICP-MS trace element concentration data for 28 elements in 97 mid-ocean ridge basalt (MORB) glasses that cover all major spreading centers as well as Tl concentration data for all mineral phases in five lherzolites from the Lherz massif, France. The ratio between the elements thallium (Tl) and cerium (Ce) is nearly constant in MORB, providing evidence that the depl...

Abstract Spinel peridotite xenoliths (one plagioclase-bearing) hosted in alkaline basalts from Tallante (southeast Spain) record the mineralogical and geochemical fingerprint of subcontinental lithospheric mantle (SCLM) evolution beneath southern Iberian margin. Mantle metasomatism fertile lherzolites caused crystallization clinopyroxene + orthopyroxene spinel clusters through percolation Mioce...

The Cavezzo meteorite, which fell on January 1, 2020, is the first meteorite detected and recovered by Italian PRISMA Fireball Network. Two specimens, weighing 3.12 g (specimen 1) 52.19 2), were collected 3 days after bolide was observed, thanks to an effective media campaign that encouraged involvement of local people. two specimens this have not only completely different lithological characte...

Abstract Mangrove forests are characterized by a high carbon storage capacity. Anthropogenic activities and the climate change threatening stability of these ecosystems, specially those that surviving on extreme environmental conditions, representing most susceptible groups. This study aims to understand geochemical differences soils mangrove forest with diverse degree development Rhizophora ma...

Abstract Melt storage and supply beneath arc volcanoes may be distributed between a central stratovolcano wider fields of monogenetic cones, indicating complex shallow plumbing systems. However, the impact such spatially variable magma conditions on volatile degassing trace element geochemistry is unclear. This study explores generation processes Tolbachik volcanic field, Kamchatka, Russia, in ...

Introduction: The angrites are an important class of differentiated meteorites, mainly ultramafic rocks, the number of which has grown to over eleven with recent finds from Antarctica and hot deserts [1, 2]. The major chemical characteristics of the angrites include a refractory element enriched, volatile element depleted, oxidized composition. Based on alkali element abundances (e.g., K/La~10x...

ABSTRACT Most of the World's platinum-group element ore deposits occur as thin stratiform layers within layered intrusions. These generally contain disseminated base-metal sulfides or chromite. However, cryptic also without chromite in what are known low-S-high deposits. The origin these is not clearly understood. Luanga Complex hosts largest elements resource South America (i.e., 142 Mt at 1.2...
