Provenance of the Lower Jurassic Badaowan and Sangonghe Formations in Dongdaohaizi Depression, Junggar Basin, and Its Constraint on the Karamaili Ocean by Yangjun Gao, Guanlong Zhang, Songtao Li, Ruichao Guo, Zhiping Zeng, Shiwei Cheng, Zelei Xue, Ling Li, Huilian Zhou, Shengqian Liu, Furong Li

“…During the Early Jurassic, the consistent subduction of the residual East Junggar Ocean induced continuous uplift in the Karamaili region, resulting in an increasing exposure of deep-seated rocks to provide sedimentary material. According to the tectonic background of the Junggar region, the results indicate that the Karamaili Ocean, as part of the Paleo-Asian Ocean, experienced three evolutionary stages: Cambrian-Early Silurian (460–540 Ma), Late Silurian-Early Carboniferous (360–440 Ma), and Late Carboniferous–Triassic (240–340 Ma).…”

Very rapid cooling of the energetic pyroclastic density currents associated with the 5 November 2010 Merapi eruption (Indonesia) by Trolese, M., Giordano, G., Komorowski, J. C., Jenkins, Susanna F., Baxter, P. J., Cholik, N., Raditya, P., Corrado, S.

“…Charring temperatures show no major differences between proximal and distal PDC deposits and are significantly lower than those that may be associated with a fast growing dome dominated by dense and vitric non-vesicular rocks. We therefore infer that the decrease in temperature from that at fragmentation (>900 °C) occurred in the very initial part of the current, <2 km from source. …”

Editorial : volumes, timescales, and frequency of magmatic processes in the earth's lithosphere by Pistone, Mattia, Taisne, Benoît, Dobson, Katherine J.

“…Thecontinental crust covers 41% of Earth’s surface (Cogley, 1984) and sits at higher elevation comparedto the oceanic crust that tends to be largely subducted. The SiO2-rich rocks that dominate the upperportions of Earth’s crust are unique in the Solar System (e.g.,Taylor, 1989) and are ultimately linkedto the presence of liquid water on Earth (Bowen, 1928; Campbell and Taylor, 1985). …”

Experimentally induced volumetric re-equilibration of plagioclase-hosted melt inclusions by Drignon, Mélissa J., Arbaret, Laurent, Cluzel, Nicolas, Nielsen, Roger L., Bodnar, Robert J.

“…Although the re-equilibration behavior MI in quartz and olivine has been studied in some detail, the process is less understood for other MI host phases such as plagioclase, a common phase in igneous rocks. A MI can re-equilibrate when it experiences pressure and temperature (PT) conditions that differ from formation PT conditions. …”

P-wave velocity structure in the crust and the uppermost mantle of Chao Lake region of the Tan-Lu Fault inferred from teleseismic arrival time tomography by Bem Shadrach Terhemba, Huajian Yao, Song Luo, Lei Gao, Haijiang Zhang, Junlun Li

“…Magmatic material in Chao Lake is likely connected to the partial melting, assimilation, storage, and homogenization of the uppermost mantle and the lower crustal rocks. The intrusions, however, seem to have suffered severe regional extension along the Tan-Lu fault driven by the eastward Paleo-Pacific plate subduction, thereby losing its deep trail due to extensional erosion.…”

Mode of Occurrence and Distribution of Critical Metal Lithium and Other Trace Elements during Coal Preparation from Jiashun High-Sulfur Coal in Guizhou Province, China by Yuxuan Zhu, Piaopiao Duan, Wenfeng Wang, Aleksei Kholodov

“…The trace elements that occurred both in the minerals and organic matters had low removal rates (<25%) using two coal preparation methods. (4) Li was more enriched in the middlings from gravity separation (98 μg/g) and in flotation tailings (102 μg/g), reaching the marginal grade (80 μg/g) of Li in coal. (5) Li in Jiashun coal may be derived from intermediate-felsic rocks at the top of the Kangdian Upland and late hydrothermal solutions.…”
