Surface Water–groundwater Interaction in the Fractured Sandstone Aquifer Impacted by Mining-induced Subsidence: 2. Hydrogeochemistry
Water quality along the Waratah Rivulet in the Woronora Lake Catchment, New South Wales (NSW), Australia, has been monitored during the last three years by the Sydney Catchment Authority. Water quality data shows changes in chemical composition due to cracking of streambeds and rockbars, and diversion of surface water into subsurface routes in the Hawkesbury Sandstone aquifer. Water quality ups...
متن کاملFailure mechanisms and surface roughness statistics of fractured Fontainebleau sandstone.
In an effort to investigate the link between failure mechanisms and the geometry of fractures of compacted grains materials, a detailed statistical analysis of the surfaces of fractured Fontainebleau sandstones has been achieved. The roughness of samples of different widths W is shown to be self-affine with an exponent zeta=0.46+/-0.05 over a range of length scales ranging from the grain size d...
متن کاملPore Length Scales and Pore Surface Relaxivity of Sandstone Determined by Internal Magnetic Fields Modulation at 2 MHz NMR
Pore length scales and pore surface relaxivities of sandstone were studied on a 2 MHz Rock Core Analyzer in this work. To determine the pore length scales of rock cores, high eigenmodes of diffusion equation were detected with optimized encoding periods in the presence of internal magnetic fields Bin. The results were confirmed by a 64 MHz NMR system. Furthermore, this methodology was combined ...
متن کاملDiagenesis of Luxembourg Sandstone
Research has been conducted into the diagenesis of the Luxembourg Sandstone. Literature studies were followed by a visit to the outcrop, after which thin sections were studied. The Luxembourg Sandstone Formation has been deposited in the Hettangian and Sinemurian, both lower Jurassic ages. A sea strait connecting the Northern German Basin and the Paris Basin was located in present day Luxembour...
متن کاملAnisotropy of sandstone permeability
Small-scale probe permeability measurements on differently oriented faces of highly compacted and quartz-cemented Viking Formation sandstones yield detailed permeability distributions that appear to be diagnostic of the grainand lamina-scale fabric of the samples. Permeability anisotropy of a single structureless'-appearing sample is low, reflected by a kV / kH-ratio of 0.7; corresponding k-di...
