Mobility of radioisotopes in marine surface sediments
Transport of a radioisotope in a sediment-water system can be retarded by sorption of the isotope to solid; which is controlled by the affinity of the radioisotope for the sediment particles. In order to study trace metal and ra- dionuclide mobility on the sea floor, the following measurements were carried out: (1)effective diffusion rates in sediments in the laboratory and on the sea floor, (2) l

Modelling passive margin sequence stratigraphy
We have modelled stratigraphic sequences to aid in deciphering the sedimentary response to sea-level change. Sequence geometry is found to be most sensitive to sea level, but other factors, including subsidence rate and sediment supply, can produce similar changes. Sediment loading and compaction also play a major role in generating accommodation, a factor often neglected in sequence-stratigraphic

Seasonal variations of Zn/Cu ratios in acid mine water from Iron Mountain, California
Time-series data on Zn/Cu weight ratios from portal effluent compositions [(Zn/Cu)water] at Iron Mountain, California, show seasonal variations that can be related to the precipitation and dissolution of melanterite [(FeII,Zn,Cu)SO4·7H2O]. Mine water and actively forming melanterite were collected from underground mine workings and chemically analyzed. The temperature-dependent solubility of Zn-Cu

Transport and natural attenuation of Cu, Zn, As, and Fe in the acid mine drainage of Leviathan and Bryant Creeks
The Leviathan and Bryant Creek (LBC) drainage system, on the border of California and Nevada, flows through overburden and waste from a former open-pit sulfur mine. The drainage contains acid mine waters with high concentrations of several trace elements, including Cu, Zn, and As, derived from oxidative weathering of sulfides in the wastes and altered bedrock. In June and October, 1982, the mainst
