Stratigraphic Analysis and Possible Tidal Influence in the Thorburn Member and Coal Brook Member, Stellarton Formation, Nova Scotia.
(2000-04-15)The Late Carboniferous Stellarton Basin is located in central Nova Scotia. It is bounded by the Cobequid Fault to the north and the Hollow Fault to the south. Dextral movement on these faults during the Carboniferous formed ... -
MONITORING BIOREMEDIATION AFTER OIL SPILLS, OLD AND NEW, USING MARSH FORAMINIFERA AS INDICATORS
(2002-04-15)Salt marshes of Nova Scotia are highly susceptible to marine oil spills. Removal of oil by natural processes is slow in low-energy environments, allowing oil to remain unaltered for many years. Marsh foraminifera, microfossils ... -
WHITE MICAS IN THE LAKE LEWIS LEUCOGRANITE, NOVA SCOTIA
(2001-04-15)The South Mountain Batholith, a peraluminous granitic complex, ranges in composition from biotite granodiorite to muscovite-topaz leucogranite. Leucogranitic rocks form minor and late components of the batholith. The Lake ... -
BEDFORM SEDIMENTOLOGY AND MORPHODYNAMICS OF SABLE ISLAND BANK
(2001-04-15)A series of shoreface-connected sand ridges occur on Sable Island Bank adjacent to Sable Island, are best developed to its south and southwest and extend as far as 23 km south of the island in water depths up to 45m. In ... -
THICKNESS AND FACIES VARIATION OF THE CARBONIFEROUS SYDNEY MINES FORMATION IN THE MORIEN SYNCLINE, CAPE BRETON ISLAND
(2001-04-15)Thirty-six drill holes from the Morien Syncline, Cape Breton Island have been analyzed to study the thickness and facies variation of the lower Sydney Mines Formation (Westphalian D). Drill holes are of the Cape Breton ... -
LATE CENOZOIC PALEOCEANOGRAPHIC CHANGES IN THE NORTHWEST PACIFIC USING RADIOLARIAN BIOSTRATIGRAPHY OF ODP SITE 1179 AND OTHERS
(2001-04-15)The radiolarian zonation of ODP Site 1179 was accessed using core-catcher samples. The data indicate that the soft sediments analyzed range from late Miocene to Recent. The radiolaria biostratigraphy of ODP Site 1179 yielded ... -
EVIDENCE OF PRECURSOR EVENTS FOR MEGA-THRUST EARTHQUAKES ON THE WEST COAST OF NORTH AMERICA
(2001-04-15)In May 1964 a 9.2 magnitude (on the Richter scale) earthquake occurred on the coast of Alaska. Since then, research has shown evidence of precursors to the earthquake using both foraminifera and diatoms, thereby detailing ... -
SCHLIEREN IN THE SOUTH MOUNTAIN BATHOLITH AND PORT MOUTON PLUTON, MEGUMA ZONE, NOVA SCOTIA
(2001-04-15)Dynamic interactions between crystals and melt can form schlieren as primary features during the various stages of the crystallization of magmas. The restricted conditions necessary for the formation and preservation of ... -
THE ZEROING PROPERTIES OF QUARTZ WITH RESPECT TO DIFFERENT DEPOSITIONAL ENVIRONMENTS
(2001-04-15)The zeroing of the luminescence signal in quartz grains by exposure to natural light is a key principle in sediment dating using optically stimulated luminescence (OSL) dating. Determination of the "equivalent dose", De, ... -
USE OF FORAMINIFERA AND THECAMOEBIANS AS RELIABLE INDICATORS OF MARINE/FRESHWATER TRANSITION ZONES IN SOUTHERN FLORIDA
(2001-04-15)The mangrove environment of Southern Florida is expansive, dominating the much of the southern coastline, including that of the southwestern Everglades. As such, it is a dynamic environment that is constantly readjusting ... -
SEISMIC VELOCITIES AND REFLECTION SEQUENCES OF WISCONSINAN GLACIAL DEPOSITS IN EMERALD BASIN (SCOTIAN SHELF)
(2001-04-15)Emerald Basin is a 2430 km2 depression located on the central Scotian Shelf approximately 40 kilometers off the coast of Nova Scotia. Sleeve-gun reflection data collected in 1994 and Ocean Bottom Seismometer data collected ... -
MONITORING OIL SPILL BIOREMEDIATION USING MARSH FORAMINIFERA AS INDICATORS
(2001-04-15)A controlled experiment was conducted in June 2000 to identify the impacts of an artificial oil spill on an Atlantic coastal salt marsh and to evaluate in situ biological remediation techniques to help restore the environment. ... -
ANALYSIS OF AQUIFER TESTS IN TWO FRACTURED ROCK WELLS, HALIFAX AREA, NOVA SCOTIA
(2001-04-15)Two drilled wells completed in fractured quartzite bedrock at sites in East Dartmouth and Waverley were tested to determine aquifer properties and well yields. Tests were conducted at different rates for various durations ... -
40Ar/39Ar LASER-PROBE STUDY OF K-FELDSPARS FROM THE NEW ROSS AREA OF THE SOUTH MOUNTAIN BATHOLITH, NOVA SCOTIA
(2001-04-15)The peraluminous South Mountain Batholith (SMB) intruded the metasedimentary rocks of the Meguma Supergroup in the Late Devonian. Mineralization of metals in pegmatite, greisen, and vein deposits are found with K-feldspar ... -
LATEST CRETACEOUS-TERTIARY STRATIGRAPHY ON THE LAHAVE PLATFORM, OFFSHORE NOVA SCOTIA, CANADA
(2002-04-15)The LaHave Platform is a relatively stable segment of the continental margin of Nova Scotia, developed along the flank of the Scotian Basin. The latest Cretaceous through Tertiary part of the succession, designated the ... -

(2002-04-15)Loons in Kejimkujik National Park (KNP), southwestern Nova Scotia, have the highest levels of mercury (Hg) concentration in blood of any loon population in North America. For the past several years, a multi-disciplinary ... -
PALYNOLOGY OF THE LOWER CRETACEOUS CHASWOOD FORMATION, ELMSVALE BASIN AND SHUBENACADIE OUTLIER, NOVA SCOTIA
(2002-04-15)The unconsolidated sand and clay deposits of the Shubenacadie and Musquodoboit basins have been documented in detailed studies since the 1950's. General mapping projects from as early as the 1900's have postulated that the ... -
