假快速岩被认为是岩石记录中古地震活动的记录。然而，基于假速石生成的断层力学解释常常受到阻碍，因为它们形成的深度很少受到限制。在这里，我们使用热年代学来确定加利福尼亚州内华达山脉假速石形成的深度。假速石形成于
Pseudotachylytes are accepted as recording paleo-seismicity in the rock record. However, the interpretation of the mechanics of faulting based on pseudotachylyte generation is often hindered because the depth at which they form is poorly constrained. Here, we use thermochronology to determine the depth at which pseudotachylytes in the Sierra Nevada, California, formed. The pseudotachylytes formed in
