This research will analyze earthquake data collected on portable seismometers during the APT89 experiment along a line from the Wyoming craton to the Western Superior Province of the Canadian Shield (Western Ontario). Shear-wave splitting will be used to investigate anisotropy, travel times of body waves will be mapped, and phase interaction with boundaries such as the Moho and core- mantle interface will be used to map lateral variations. Spanning two major geologic boundaries, the experiment was designed to study the seismological properties of the crust, upper mantle and core- mantle boundary along the traverse.

这项研究将分析便携式地震仪上收集的地震数据， 地震仪在APT 89实验沿着从 怀俄明州克拉通至加拿大西部上级省 地盾（西安大略）。 剪切波分裂将用于 研究各向异性，将绘制体波旅行时间， 与边界的相位相互作用，如莫霍面和核心， 地幔界面将用于绘制横向变化。 跨越 两个主要的地质边界，实验的目的是研究 地壳、上地幔和地核的地震学性质， 地幔边界沿着导线。
