As part of this project, more than 3500 gravimetric observations were acquired in the Bathurst Mining Camp, with an average spacing of 1-2 km, in 2006. The gravimetric data was reduced for an average crustal density value of 2.77 g/cm3 to obtain the Bouguer anomaly, which was analyzed and used to obtain 2.5D gravity models along five transects crossing the Bathurst Mining Camp. As a result of gravity modeling, a model of the general geometry of the main geological groups of the Bathurst Mining Camp (Fournier, California Lake, Tetagouche, and Miramichi) was obtained, which suggests that the Nine Mile Syncline is an open fold, and the Tetagouche Anticline is a gentle fold. Both folds are non-cylindrical and inclined, with their axial planes dipping in the 293° N direction: the angle of vergence of the folds increases towards the northeast of their axes. The structures under the Tetagouche Anticline axis gradually get deeper towards the Northeast reaching a maximum depth of 4 km. The depth of the structures modeled under the axis of the Nine Mile Syncline varies between 2 and 9 km, the deepest part being towards the center of the Bathurst Mining Camp; towards the northeast of its axis, the structures reach an intermediate depth of 4 km while towards the southwest they are 2 km deep on average.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen El Campo Minero de Bathurst es un importante distrito minero de metales básicos en Nuevo Brunswick, Canadá, que fue un área de interés para el proyecto de la Fase 3 de la Iniciativa de Geociencias Dirigidas del Servicio Geológico de Canadá. Como parte de este proyecto, en 2006 se adquirieron más de 3.500 observaciones gravimétricas en el campo minero de Bathurst, con una separación media de 1 a 2 km. Los datos gravimétricos se redujeron a un valor medio de densidad de la corteza de 2,77 g/cm3 para obtener la anomalía de Bouguer, que se analizó y utilizó para obtener modelos gravimétricos en 2,5D a lo largo de cinco transectos que cruzan el campo minero. Como resultado del modelo gravimétrico, se obtuvo un modelo de la geometría general de los principales grupos geológicos del campo (Fournier, California Lake, Tetagouche y Miramichi), que sugiere que el Sinclinal de Nine Mile es un pliegue abierto, y el Anticlinal de Tetagouche es un pliegue suave. Ambos pliegues son no cilíndricos e inclinados, con sus planos axiales sumergidos en la dirección 293° N: el ángulo de vergencia de los pliegues aumenta hacia el noreste de sus ejes. Las estructuras bajo el eje del anticlinal de Tetagouche se hacen gradualmente más profundas hacia el noreste, alcanzando una profundidad máxima de 4 km. La profundidad de las estructuras modeladas bajo el eje del Sinclinal de las Nueve Millas varía entre 2 y 9 km, siendo la parte más profunda hacia el centro del campo Minero de Bathurst; hacia el noreste de su eje, las estructuras alcanzan una profundidad intermedia de 4 km mientras que hacia el suroeste tienen una profundidad media de 2 km.]]></p></abstract>
