Crustal extension and formation of the Mineral Mountains core complex, Utah, involved tilting of the Mineral Mountains batholith and associated faults during hanging wall and footwall deformation. The batholith was folded in the hanging wall of the Beaver Valley fault between 11 and 9 million years ago yielding about 45 degrees of tilt. Subsequently, the batholith was unroofed along the Cave Canyon detachment fault, and the batholith and fault were tilted approximately 40 degrees during footwall uplift. Recognition of deformed dikes beneath the detachment fault establishes the importance of footwall tilt during formation of extensional core complexes and demonstrates that footwall rebound can be an important process during extension.
犹他州矿山区核心杂岩的地壳伸展与形成过程中，在悬挂壁和下盘变形期间，矿山区岩基及相关断层发生了倾斜。1100万至900万年前，岩基在比弗谷断层的悬挂壁发生褶皱，产生了约45度的倾斜。随后，岩基沿着洞穴峡谷拆离断层被剥露，在下盘隆升过程中，岩基和断层又倾斜了约40度。对拆离断层下方变形岩脉的识别，确立了下盘倾斜在伸展核杂岩形成过程中的重要性，并表明下盘回弹可能是伸展过程中的一个重要过程。
