analysis. Most water production occurred from two fractured and weathered zones which are separated by an interval of unweathered granite. The fractures identified in the drilling reports show various depth ...
ratios of stream water at baseflow periods were uniform regardless of location and time, and were indistinguishable from those of the weathered andesite bedrock . The Sr isotopic and elemental data indicate ...
weathering ) from near-surface rocks annually, nearly tripling previous estimates of global rock-derived N fluxes. In N-limited mountainous watersheds, bedrock -derived N may represent a majority of N available ...
/ weathered zone ; a possible storage and migration of underground water in the surveyed area. In addition, the saturated alluvium deposit base (sand/gravel) combined with the weathered /fractured bedrock surface ...
[34,37,69,70,73,74]. Plant and water samples were collected between December 2015 and June 2017 from a total of 13 archaeological and agricultural sites from distinct ecological zones throughout the Basin of Mexico ...
with significant weathering and oxidation were inferred to be most important to the groundwater flow system. Using the fluid saturation method, bedrock matrix porosities were calculated based on 89 hand samples from ...
on the local topography, availability of moisture would lead to the denser vegetation. The kind of bedrock could also contribute to differences in plant production [8, 9]. To extrapolate from the vegetation ...
, and the river tends to meander. The mixed-energy zone is the lowest-energy zone in the estuary and therefore is the site of the deposition of finest-grained sediments from both marine and fluvial sediment loads ...
produced by its parent Actinium by emitting an alpha particle. Upon alpha recoiling mechanism 222Rn is effectively transferred to the water -filled pore spaces and fracture zones from the solid matrix(2 ...
the lower permeability core, respectively). With the relatively thin vadose zone beneath P6, recharge reaches the water table relatively quickly; from here it is transported laterally rather than stored ...
