利用S接收函数对南美大陆及其邻区壳幔岩石圈的结构和厚度进行了研究。在所有站点都检测到莫霍不连续，从大陆海岸以下18公里到安第斯地区的80公里。岩石圈-软流圈边界深度可以在位于50 ~ 160 km稳定区域的台站下方清晰地探测到。当测量站位于俯冲带附近时，这一阶段的识别变得更加困难。我们还观察了俯冲到220公里深处的海洋岩石圈的底部。
We make use of S receiver function to investigate the structure and thickness of the crust and mantle lithosphere in the South American continent and adjacent areas. The Moho discontinuity has been detected at all stations and goes from 18 km beneath the coast of the continent to 80 km in the Andean region. The depth of the lithosphere‐asthenosphere boundary can be clearly detected below those stations that are located on stable areas from 50 km to 160 km. The identification of this phase becomes more difficult when the stations are located near subduction zones. We also observed the base of the subducted oceanic lithosphere down to depths of 220 km.
