Five floor-fractured craters (FFCs), Lavoisier crater and four surrounding it (Lavoisier C, E, F, H), are distributed along the boundary between northwestern part of Oceanus Procellarum highlands. This study examines uplifted or exposed materials on fractured floors these five impact using petrological, mineralogical, morphological analyses. We inferred processes that from subsurface to floor C...

Coal mining originates environmental impacts on soil and water bodies, including the leaching of Potentially Toxic Elements (PTEs) Polycyclic Aromatic Hydrocarbons (PAHs) in mine waste piles. This research aims to identify characterize changes induced by self-burning Technosols from a coal pile means comprehensive hydropedological assessment encompassing geochemical, mineralogical, hydrological...

Historical releases and subsequent migration of toxic metals and radionuclides within the soil and vadose zone at various sites over the DOE Complex pose serious technological challenges, including the design and implementation of cost-effective remediation and/or monitoring strategies. This requires knowledge of the fundamental processes that govern contaminant mobility and reactivity with the...

abstract low molecular weight carboxylic acids (lmw) play an important role in improving the bioavailability of soil nutrients. nonexchangeable soil k, trapped between the interlayers of clay minerals, is an important source of k for plants in many soils. the objectives of this study were to determine the effect of selected lmw organic acids on the release of k from micaceous minerals and to in...
