Özet:
In the Roberts Mountains of north-central Nevada, several large masses of the autochthonous carbonate succession overlie the highly deformed siliciclastic succession of the Roberts Mountains allochthon (RMA). These carbonate masses, or tectonic erratics, were plucked from the underlying autochthon and carried in the base of the upper plate of the post-Antler Orogeny Henderson thrust as it ramped structurally upwards and eastwards. Kinematic indicators in the form of folds and fractures within the carbonate masses at Henderson Summit, Vinini Creek, Mineral Hill, and Lone Mountain show a general eastward stress direction. Intense brecciation is observed in the lower parts of the carbonate masses and in the immediately underlying siliciclastic strata of the RMA. Based on observations and kinematic evidence, the carbonate masses at Henderson Summit, Vinini Creek, Mineral Hill, and Lone Mountain are interpreted to be tectonic erratics, which in turn further supports and extends the tectonic erratic hypothesis.
