Desarrollo de calcretas en cavidades cársticas y/o de raíces: Las calcretes Cuaternarias de la Isla Gran Cayman (Calcrete development in root/karstic cavities: Quaternary calcretes from Grand Cayman)Download
The ruggest karst terrain that is developed on the dolostones of the Miocene Caayman Formation on Grand Cayman includes numerous large cavities that formed through the activity of tree roots. The surfaces of those cavities are coated with laminated calcrete crusts that are up to 8 cm thick. These...
Surface mining for bitumen extraction results in production of tailings that are deposited into large ponds. Tailings in the ponds support diverse microbial communities capable of metabolizing organic compounds and producing biogenic gases (methane, CH4 and carbon dioxide, CO2). Because of low...
Surface mining activities cause severe adverse effects on soils. Scientists across the world have used different physical, chemical and biological reclamation techniques to recover mining disturbed areas. The effectiveness and efficiency of reclamation techniques is crucial to reclamation...
