Foreword: environmental geoscience research in the Atlantic region.(SPECIAL ISSUE)
July 1, 2006... It has been 10 years since Atlantic Geology first published a whole issue dedicated to "environmental" geoscience, at that time concerning problems associated with the Lower Palaeozoic rocks of the Meguma Group (or Supergroup) (Zentilli and Fox, 1997). In the mid-1990s, the label...

Carbonate blocks found in muddy sediment off Cape Breton Island, Nova Scotia: pieces of small authigenic carbonate mounds and vents related to hydrocarbon seeps?
July 1, 2006... ABSTRACT Carbonate blocks brought up from the seafloor during drag fishing in a small restricted area offshore northern Cape Breton Island are irregularly shaped and range in size from 6 [cm.sup.3] to >1 [m.sup.3]. They have smooth to "clinkery", dendritic, or "popcorn-surface"...

Relict seawater as source of stratified groundwater in glaciated estuarine valleys: an example from Fredericton Junction, New Brunswick.
July 1, 2006... ABSTRACT Recent investigations of the local geology and hydrogeological environment for the Village of Fredericton Junction, New Brunswick, identified a lower bedrock aquifer as the main water supply aquifer for both municipal and domestic wells. Within the aquifer, potable water...

Weathering of Devonian monzogranites as recorded in the geochemistry of saprolites from the South Mountain Batholith, Nova Scotia, Canada.
July 1, 2006... ABSTRACT Parent mineralogy, paleoenvironment, and subsequent diagenetic and erosional history contribute to the nature of the paleoweathering profiles (saprolites) developed on the South Mountain Batholith. Saprolites of three different ages (pre-Carboniferous, pre-Triassic, and...

Geoscience at the nanometre scale: review of analytical transmission electron microscopy applications.
July 1, 2006... ABSTRACT This paper describes applications of analytical Transmission Electron Microscopy (TEM) in the geosciences. The topics include: 1) sulphide-mineral oxidation; 2) trace-metal attenuation by secondary Mn oxides; 3) silicate weathering; 4) transition-metal valence in minerals; and...
