Authigenic Carbonates: Carbonate minerals precipitated in place within sedimentary environments as a direct result of geochemical reactions, typically linked to microbial activity at cold seep areas.

Karst-bauxite formation during the Great Oxidation Event indicated by dating of authigenic rutile and its thorium content Alexandre Raphael Cabral Armin Zeh Scientific Reports (2023) ...

Coatings were grown on the AZ31 Mg alloy by a hard anodizing process in the hot glycerol phosphate-containing electrolyte. Anodizing conditions were optimized, maximizing corrosion resistance ...

川西前陆盆地（WSFB）须家河组三段（Xu3 Member）储层埋深普遍超过4500米，其自生高岭石（authigenic kaolinite）的"南北分异"现象长期困扰勘探人员——北部高岭石晶形完整如"书册堆叠"，南部却多见伊利石（illite）和绿泥石（chlorite）的"改头换面"。

Phosphorus (P) is an essential nutrient for living organisms and cannot be replaced or substituted. In this paper, we present a simple yet efficient membrane free electrochemical system for P removal ...

撰文丨王聪 编辑丨王多鱼 排版丨水成文 在海洋中，几乎永不停歇的颗粒流——其中大部分由生物过程产生——从阳光普照的海面沉入深海的黑暗之中，这一过程被称为海洋生物泵，它将化学能和生命所需的元素输送到深海，有助于控制地球气候并为深海生态系统提供能量。 而一篇最新 Nature 论文 ...

In addition, the shallow-water, fossiliferous nature of the sedimentary facies indicates locally well-oxygenated conditions, which is preferable for capturing seawater δ 238 U values without the ...

The cycling of barium (Ba) is closely linked to marine biogeochemical processes. Barium and its isotopes are commonly used as tracers for marine productivity, seawater alkalinity, and ocean ...
