2012/3/30
Sequestration of organic matter (OM) in sediments is a fundamental biogeochemical process that regulates planetary temperature, the flux of free oxygen to the atmosphere and oceans, and the distributi...
Role of colloidal particles for hydrogeochemistry in As-affected aquifers of the Hetao Basin, Inner Mongolia
aqueous geochemistry arsenic colloid shallow groundwater
2017/8/9
High As groundwater was found in shallow aquifers of the Hetao Basin, Inner Mongolia, which has caused serious chronic arsenism. Groundwater particles are ubiquitous in natural aquifers, and significa...
Crystallization Processes and Role of Compositional Convection in the Macrolayer Formation in a Small Layered Complex
quartz-gabbro Crystallization Processes Macrolayer Formation
2009/7/8
The Peloso complex is a 1000m thick gabbroic body composed of two main layered zones (ZA and ZB) that are made up of cyclic macrolayers of olivine gabbro, leucogabbronorite and anorthosite cumulates, ...
Linking allochthonous dissolved organic matter and boreal lake sediment carbon sequestration: The role of light-mediated flocculation
Linking allochthonous dissolved organic matter boreal lake sediment carbon sequestration The role of light-mediated flocculation
2014/4/21
We measured flocculation of dissolved organic carbon (DOC) in the water from a humic lake (DOC = 14.9 mg C L-1) and from an adjacent mire (DOC = 25.7 mg C L-1), in in situ enclosure experiments with d...
