We are
developing and testing a new model for the ~ 1.1 Ga collisional orogen
along the southern margin of Laurentia with specific emphasis on the
Llano uplift of central Texas that exposes the core of the orogen and
the Sierra Diablo foothills of west Texas where the metamorphic core is
thrust over foreland sedimentary rocks in a narrow, Grenville-age
transpressional belt. |
