Extending the western North American Proterozoic and Paleozoic continental crust through the Mojave Desert: comment and reply

Article Abstract:

The presence of rocks from the Proterozoic and early Paleozoic ages in the Mojave Desert, CA, is not proof that there is a miogeoclinal-cratonal hingeline in the area. This is the contention of some observers who maintain that stratigraphic data shows that no such hingeline exists in the region. On the other hand, observers say that the hingeline in the area applies to those areas of the Mojave Desert that are not properly preserved. Furthermore, these same observers interpret the stratigraphic data for the region as sufficient evidence that a hingeline is present in the area.

Timing of collision of the North and South China blocks: controvesy and reconciliation

Article Abstract:

The time of integration of the North and South China blocks has been debated for years. Different reconstructions of the integration seem to yield contrasting results, mostly pointing to either the Paleozoic age or the Late Triassic age. A new model based on the Qinling tectonic evolution is proposed to reconcile conflicting research yields. Studies that have used this model indicate that the gradual drifting away of the South Qinling orogen occurred during the middle to late Paleozoic period.
