The Miaoershan uranium(U)ore field in northeastern Guangxi is one of the important granite-related U deposits in south China and is closely related to the Douzhashan U-bearing *** Douzhashan granite contains primary U-rich accessory minerals,including monazite(UO2=0.98-1.75 wt%)and xenotime(UO2=1.48-6.14 wt%).Primary monazite and xenotime yield chemical ages of 231±28 Ma and 230±38 Ma by electron microprobe analysis and U-Pb isotopic ages of 220±6 Ma and 211±7 Ma by laser ablation-inductively coupled-mass spectrometry *** ages demonstrate that the Douzhashan granite formed during the period of Indosinian magmatic *** scattered electron imaging shows that monazite and xenotime are commonly altered to assemblages of low-U synchisite and apatite,which was associated with loss of U to hydrothermal fluids.U-Th-Pb analyses of secondary apatite yielded a chemical age of 136±17 Ma,which corresponds to the timing of Cretaceous-Tertiary crustal extension in south *** suggest that the heat and CO2required for mineralization was the result of Yanshanian crustal extension,and that this triggered the breakdown of U-rich accessory minerals in the Douzhashan U-bearing *** remobilization from the Douzhashan granite provided materials for mineralization within the granite and/or surrounding country ***,a combination of Indosinian compression and Yanshanian extensional overprint produced the hydrothermal U deposits associated with the Douzhashan granite.

微塑料(Microplastics, MPs)为粒径小于5 mm的塑料碎屑或颗粒。塑料垃圾在海洋中经一系列物理、化学反应或生物作用,分解碎化形成海洋微塑料。渤海为半封闭海域,与外海的交流能力较弱,渤海表层微塑料丰度明显高于黄海、东海和南海等其他开放海域,渤海的莱州湾、渤海湾和辽东湾三个湾区微塑料丰度也要高于其他典型湾区。文章综述了渤海微塑料的丰度、粒径、形状、化学成分、颜色等统计结果,并阐述微塑料在海水中分布会对海洋生态环境带来的危害。最后比较分析了显微镜法、傅里叶变换红外光谱法和拉曼光谱等目前微塑料主流分析方法适用范围。

Lactate is present at a high level in the microenvironment of mammalian preimplantation embryos in vivo and in vitro. However, its role in preimplantation development is unclear. Here, we report that lactate is highly enriched in the nuclei of early embryos when major zygotic genome activation(ZGA) occurs in humans and mice. The inhibition of its production and uptake results in developmental arrest at the 2-cell stage, major ZGA failure, and loss of lactate-derived H3K18lac, which could be rescued by the addition of Lac-Co A and recapitulated by overexpression of H3K18R mutation. By profiling the landscape of H3K18lac during mouse preimplantation development, we show that H3K18lac is enriched on the promoter regions of most major ZGA genes and correlates with their expressions. In humans, H3K18lac is also enriched in ZGA markers and temporally concomitant with their expressions. Taken together, we profile the landscapes of H3K18lac in mouse and human preimplantation embryos, and demonstrate the important role for H3K18lac in major ZGA, showing that a conserved metabolic mechanism underlies preimplantation development of mammalian embryos.
