The U–Pb (249 to 1 Ma) and zircon fission track (ZFT) ages (65 to 1 Ma) suggest thermal annealing during later basalt transport, with < 1 to 203 Ma gaps between the U–Pb and ZFT ages.
Given the wide distribution of mafic rocks (especially basalt) on the continental surface, basalt weathering is of global significance to the inputs of Ni to rivers. Studies on Ni isotopes have demonstrated differences in δ 60 Ni values between the upper continental crust (0.12 ± 0.15‰, Wu et al., 2022 ) and rivers (0.12–1.35‰, Cameron ...

Basalt dusts contain several agricultural essential elements (Ca, Mg, K, P, S and Fe) and beneficial elements (Na and Si) for crops. Basalt dusts are naturally obtainable (Gillman et al., 2002, Klein, 2002) and are environmentally sound as a soil amendment.Curiosity in the efficiency of crushed basalt to amend poor soils (especially …
The 40Ar–39Ar dating reveals three episodes of basaltic volcanism in eastern Guangdong of SE China since the late Eocene (i.e., 35.5, ~20 and 6.6 Ma). The …
This study examines the spatial distribution of vegetation and its elevation relationship in central China's salt marsh wetlands, aiming to improve our understanding of biomass distribution. Using a combination of remote sensing modeling and field observations ( Berner et al., 2018 ; Byrd et al., 2018 ; Chen and Kirwan, 2022 ), we …

The length of basalt fiber produced by the company is usually set to a multiple of 3 mm. Hence, the frequency distribution of the skeleton gap axis length in the range of 0 ∼ 3 mm, 3 ∼ 6 mm and 6 ∼ 9 mm can be used to characterize the frequency distribution of basalt fibers with 3 mm, 6 mm and 9 mm, respectively.
Basalt fiber (BF), one of the four major high-tech fibers used in China, plays a reinforcing role and enhances the properties of composite materials [10]. These properties include natural compatibility, superior mechanical performance, stable chemical characteristics, and outstanding high temperature performance [11].
