crustal scale reflection seismic investigations in the bathurst mining camp new Brunswick canada
Tectonophysics, 2011Co-Authors: Saeid Cheraghi, Alireza Malehmir, Gilles BellefleurAbstract:Abstract The Bathurst Mining Camp, northern New Brunswick, Canada contains the super giant Brunswick No. 12 massive sulphide deposit and the smaller, now abandoned, Brunswick No. 6 deposit. Discoveries of additional base metal deposits in the camp require a better understanding of geological structures at depth. To this end, reflection seismic data in the Brunswick No. 6 area were acquired along three 2D profiles in 1999, with a total length of about 30 km. We have recovered, processed and interpreted these seismic data in conjunction with petrophysical and geological data from the study area. The seismic data and the borehole geophysical data allow a better understanding of both the shallow and deep structures (to 9 km depth) in the area. The seismic data show steeply dipping structures of the Brunswick No. 6 area, many of which reach the surface and allow for correlation with the surface and borehole geological information. Finite-difference modeling of major geological formations constrained with borehole petrophysical measurements indicates good correlation between the observed seismic and the synthetic data. A sequence of seismically reflective and transparent zones indicates a thrust stack in the Brunswick No. 6 area. The contact between the reflective and transparent zones is a series of faults bringing the two units over each other. A reflective package is observed in all three profiles and correlates well with the Brunswick horizon, the key mineralized zone in the study area. The Brunswick horizon extends down to depth greater than 3 km, increasing the hope for discovery of deeper base metal deposits. Two other sets of reflections are also observed in all three profiles in the depth range of about 5–8 km. We interpret them as two sets of thrusted sheets, which could be an indication that the Brunswick belt extends down to a maximum depth of 8 km.

reflection seismic imaging and physical properties of base metal and associated iron deposits in the bathurst mining camp new Brunswick canada
Ore Geology Reviews, 2010Co-Authors: Alireza Malehmir, Gilles BellefleurAbstract:The Bathurst Mining Camp, northern New Brunswick, Canada is a major base-metal producing region that includes the Brunswick No. 12 and smaller past-producing Brunswick No. 6 deposit. Sustaining mining activity in the camp requires exploration of orebodies near and adjacent to existing mines. In this paper, we recovered, re-processed, modeled and interpreted a 2D high-resolution reflection seismic profile in the vicinity of the Brunswick No. 6 open pit with the aim of providing key information on the geological structures associated with mineral deposits at depth. The seismic data quality is good to excellent with numerous strong reflections in raw shot gathers, resulting from a careful survey design that included test shots and a priori considerations for the geological environment. Physical properties of lithological units and mineralized zones including gamma–gamma, conductivity, magnetic susceptibility, density and sonic data were studied from borehole geophysical measurements conducted near the mine. This helped to correlate seismic data and shows that the Brunswick Horizon, a key ore-prospecting horizon, and associated lithological contacts are strongly reflective. The results demonstrate that reflection seismic imaging has been particularly effective for imaging steeply dipping structures of the Brunswick No. 6 deposit many of which intersect the surface and thus allow for correlation with surface geology. Massive sulfides and iron formation of the Brunswick Horizon are identifiable locally within a distinctive reflective package that can be used as a broad guide in the region for the exploration of deep base-metal deposits. In several locations, a change from highly reflective to semi-transparent seismic character is explained by the presence of faults that juxtapose highly reflective lithological units with seismically transparent lithologies.

relation between physician characteristics and prescribing for elderly people in new Brunswick
Canadian Medical Association Journal, 1994Co-Authors: W Davidson, D W Molloy, G Somers, Michel BedardAbstract:OBJECTIVE: To determine whether there is a relation between physician characteristics and prescribing for elderly patients. DESIGN: Descriptive study linking two provincial databases. SETTING: New Brunswick. PARTICIPANTS: All general practitioners (GPs) in New Brunswick who ordered at least 200 prescriptions for elderly beneficiaries of the New Brunswick Prescription Drug Program between Apr. 1, 1990, and Mar. 31, 1991; eligible GPs accounted for 376 (40%) of all physicians with a general licence in New Brunswick. MAIN OUTCOME MEASURES: GPs9 personal and professional characteristics (age, sex, family practice accreditation, country of training and number of years in practice), practice characteristics (number of practice days, number of patients seen and medical services provided per day, average amount of billing per patient, total number of patients seen and their average age, and total amount of billings) and number of prescriptions by category of drug. RESULTS: High prescribers and low prescribers did not differ significantly in age, number of years in practice, mean practice size or patient age. Compared with the low prescribers the high prescribers were more likely to be male, have been trained in Canada and be qualified by the Canadian College of Family Physicians. Also, they had more practice days, saw more patients per day, performed more services per day, billed more per patient and billed on average 30% more during the study period. Overall, the high prescribers ordered on average 45% more prescriptions than the low prescribers. CONCLUSION: There is a significant relation between certain physician characteristics and prescribing behaviour. Further study is required to examine the relation between these variables and patient outcomes.
