Biogenic productivity of Lake Tanganyika is highly dependent on seasonal upwellings of anoxic deep waters. We investigated the shell of freshwater bivalve Pleiodon spekii as a geochemical archive of these periodic hydrological changes tuned by the monsoon regime. The results of a 2-years-long geochemical survey of the coastal waters 5 performed on the dissolved and particulate fractions were pu...

The Cretaceous Western Interior Seaway Drilling Project was begun in 1991 under the auspices of the U.S. Continental Scientific Drilling Program. It was intended to be a multidisciplinary study of Cretaceous carbonate and silicicl.tic rocks in cores from bore holes along a transect across the Cretaceous Western Interior Seaway. The study focuses on middle Cretaceous (Cenomanian to Campanian) st...

This report discusses the geology and mineral potential of a segment of the Coast Mountains, east of Princess Royal Island (in NTS area 103H) termed the Khutze River area. The information presented is based on public domain reports and old staking records. In 1999, a regional stream sediment survey was conducted in the area by the Ministry of Energy and Mines. The results of the geochemical sur...

REASONS FOR PERFORMING STUDY We hypothesised that the apparent geographical distribution of equine grass sickness (EGS) is partly attributable to suboptimal levels of soil macro- and trace elements in fields where EGS occurs. If proven, altering levels of particular elements could be used to reduce the risk of EGS. OBJECTIVES To determine whether the geographical distribution of EGS cases in ...
