We demonstrate successful crustal imaging via teleseismic P‐wave coda autocorrelation, using data recorded on a 261 station array of vertical‐component high‐frequency geophones in the area of the Bighorn Mountains, Wyoming, U.S.A. We autocorrelate the P‐wave coda of 30 teleseismic events and use phase‐weighted stacking to yield seismic profiles comparable to low‐passed versions of those produced via controlled‐source vertical seismic reflection. Our process recovers reflections from the bottoms of the Bighorn and Powder River basins that flank the Bighorn Mountains. We also identify a mid‐crustal reflector that aligns with a region of increased reflectivity, previously interpreted as a Precambrian province boundary. Our results demonstrate the utility of crustal imaging with teleseismic P‐wave coda energy using modern large‐array seismic data, and they corroborate previous interpretations of crustal structures in the study area.

美国怀俄明州大角山地区地壳和盆地结构的远震P波尾波自相关成像

我们使用在美国怀俄明州比格霍恩地区的261个垂直分量高频地震检波器的261站阵列上记录的数据，通过远震P波尾波自相关演示了成功的地壳成像我们对30个远震P波尾波进行了自动相关地震并使用相位加权叠加来产生地震剖面，该剖面与通过受控源垂直地震反射产生的地震剖面的低通版本相当。我们的过程从比格霍恩山脉两侧的比格霍恩河和粉河盆地的底部恢复反射。我们还确定了与反射率增加的区域对齐的中地壳反射器，该区域以前被解释为前寒武纪的边界。我们的结果证明了使用现代大阵列地震数据利用远震P波尾波能量进行地壳成像的实用性，
