Seismic and thermal measurements on the Nova Scotia slope

根据岩石圈伸展期间发生的火山活动的数量，裂谷大陆边缘主要分为火山和非火山两类。新斯科舍省边缘位于一个独特的位置，南部是火山边缘，北部是非火山边缘，这为研究两种边缘类型之间过渡的性质提供了机会。新斯科舍近海结晶基底的主要结构已经在最近提供给我们的多通道地震反射剖面上成像，这可能与这种转变有关。此外，火山与非火山边缘的界线与沉积构造的显著变化是一致的。为了更好地了解过渡性构造的性质及其对油气资源生成的潜在影响，我们建议在新斯科舍省大陆斜坡的剖面上进行地球物理测量，包括两条地震折射线和完成四条海洋热流样带。这些数据与我们的发现基金研究奖励直接相关，并且是另外两个已获得资助的联合研究项目所特别需要的。

Two primary classes of rifted continental margins, volcanic and non-volcanic, have been recognized based on the amount of volcanism that occurs during lithospheric extension. The Nova Scotia margin is located in a unique position bounding volcanic margins to its south and non-volcanic margins to its north, providing an opportunity to study the nature of the transition between the two margin types. Major structures within crystalline basement offshore Nova Scotia have been imaged on multi-channel seismic reflection profiles, recently made available to us, that may be related to this transition. The volcanic to non-volcanic margin boundaries, in addition, are coincident with significant changes in sedimentary structures. We propose to conduct geophysical measurements, including two seismic refraction lines and the completion of four marine heat flow transects, on profiles across and along the Nova Scotia continental slope to better understand the nature of the transitional structures, including their potential influence on the generation of hydrocarbon resources. These data are directly related to our Discovery Grant research awards and are specifically required by two other joint research projects that have been funded.
