Rare metals, such as lithium and cobalt used in rechargeable batteries, have increased value demands for them escalates. Concentrations of lithium-bearing minerals are found closed-basin brines, granitic pegmatites, associated rocks containing spodumene (LiAl(SiO 3 ) 2 various other economic minerals. The recently discovered Dahongliutan Li mineral occurrences hosted by a pegmatite dyke swarm NW China, an area that is also prospective Be, Rb, Nb, Ta mineralisation. However, the high altitude...
Abstract The search for new phases is an important direction in materials science. phase transition of sulfides results significant changes catalytic performance, such as MoS 2 and WS . Cubic pentlandite [cPn, (Fe, Ni) 9 S 8 ] can be a functional material batteries, solar cells, fields. However, no report about the properties other exists. In this study, unit‐cell parameters pentlandite, sulfur‐vacancy enriched hexagonal (hPn), boundary between cPn hPn are determined first time. Compared to...

It is well known that a genetic link exists between the formation of ultramafic-rocks-hosted PGE-Cu–Ni sulfide deposits and eruption associated continental flood basalts. We here present new model for relationship Cu–Ni located along northeastern margin Tarim internal basalt. Sr–Nd isotope Hf two-stage crust ages TDMc indicate whereas have Neoproterozoic Mesoproterozoic lithology contamination, surrounding rocks in Beishan (Pobei) Central Tianshan do not lithologies. propose this result...
Natural remanent magnetization and self-demagnetization on high-susceptibility bodies are two important factors affecting magnetic data inversion. We propose a framework for the inversion interpretation of anomalies, in which significant present simultaneously. The is based assumptions that external applied field internal uniform deflection total direction negligible. First, vector distributions obtained from by estimating direction, then inverting intensity distribution, using inferred as...
In the solar system, oldhamite (CaS) is generally considered to be formed by condensation of nebula gas. Enstatite chondrites, one most important repositories oldhamite, are believed representative material that Earth. Thus, formation mechanism and evolution process great significance deep understanding nebula, meteorites, origin Earth, C-O-S-Ca cycles Until now, has not been reported occur in mantle rock. However, here we show through reaction between sulfide-bearing orthopyroxenite molten...

The Gayahedonggou magmatic Cu-Ni sulfide deposit was recently discovered in the East Kunlun orogenic belt (Northern Tibetan Plateau, China). mineralization this region is associated with mafic–ultramafic intrusions. To date, formation age and metallogenic model of these ore-bearing intrusions have not been studied systematically. In paper, petrology, zircon U-Pb chronology, geochemistry wehrlite quartz diorite are investigated. results show that isotopic 419.9 ± 1.5 Ma an average εHf(t)...

The phase transitions among the high-pressure polymorphic forms of CaCO 3 (cc-I, cc-II, cc-III, and cc-IIIb) are investigated by dynamic diamond anvil cell (dDAC) in situ Raman spectroscopy. Experiments carried out at room temperature high pressures up to 12.8 GPa with pressurizing rate varying from 0.006 GPa/s 0.056 GPa/s. In observation shows that increase pressure, calcite transforms cc-I cc-II ∼ 1.5 cc-III 2.5 GPa, independent rate. Further, as pressure continues increase, cc-IIIb begins...
Tridacna squamosa, Lamarck, 1819 (Bivalvia Cardiida Cardiidae, known as the fluted giant clam) is one of largest-sized bivalve shells, which equipped with a strong and tough bioceramic shell to effectively protect itself from attack predators. To better understand mechanical defense mechanism, relationship between microstructure, composition, properties squamosa was investigated. We find that composed aragonite CaCO3 small portion organic matter, are well-arranged, assembling multiscale,...
Zircon (ZrSiO4) provides a good pressure-holding environment for ultra-high-pressure metamorphic minerals during crust exhumation due to its high incompressibility and chemical stability. At pressure, the zircon can transform reidite. Previous studies show much higher phase-transition pressures at room temperature than those (>1000 K) kinetic hindrance. To further investigate kinetics of zircon–reidite phase transition relatively low temperatures, boundary 298–800 K was determined using...
