FIXATION OF SULPHUR DURING FRAMBOIDAL PYRITE DEVELOPMENT IN A PETROLEUM RESERVOIR IN CRETACEOUS VOLCANICS IN THE ANDES: IMPLICATIONS FOR CU METALLOGENESIS
(2002-04-15)
El Soldado, Chile, is a giant strata-bound copper deposit hosted in Lower Cretaceous basalt and rhyodacite. Previous work suggested that copper was concentrated preferentially where hydrothermal copper-rich solutions ...
DISTRIBUTION, MINERALOGY, AND POTENTIAL RECOVERY OF RUTILE FROM THE CHUQUICAMATA PORPHYRY COPPER DEPOSIT OF NORTHERN CHILE
(2002-04-15)
Rutile is a common accessory phase in altered porphyry copper ores (up to 1 wt. % of the host rock), yet it is generally lost to tailings, despite its relatively high price. Ti metal (sponge) is about 5 times the price of ...
DISTRIBUTION OF MN IN THE ENVIRONMENT; AN EXAMPLE FROM GEOLOGY, SURFACE WATER, LAKE SEDIMENT AND TILL IN CENTRAL NOVA SCOTIA
(2002-04-15)
This study involves an examination of Mn in the environment in central Nova Scotia. Since Mn has been mined and occurs in many localities, the study was initiated in order to determine whether Mn could possibly pose an ...
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 ...
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 ...
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. ...
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 ...
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, ...
MERCURY IN TILL AND BEDROCK, KEJIMKUJIK NATIONAL PARK AREA, NOVA SCOTIA
(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 ...
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 ...
