Slab in the wrong place: lower lithospheric mantle delamination in the last stage of the Eastern Carpathian subduction retreat: comment and reply

Article Abstract:

A novel tectonic model for the Eastern Carpathian Mountains was developed in an attempt to determine the cause of the Sinaia fault in the region. The proposed framework, based on structural results derived from Pliocene Brasov and Gheorghieni basins, identifies gliding gravitational nappe, mantle upwelling and lithospheric delamination as the potent causes of the fault. Such a conclusion, however, may be deemed argumentative since the use of small-scale inferred displacement in explaining regional tectonic covering hundreds of kilometers is erroneous.

Pleistocene relief production in Laramide mountain ranges, western United States: comment and reply

Article Abstract:

Eric E. Small and Robert S. Anderson suggested that glacial erosion of valleys caused significant isostatic uplift of summit areas in the Laramide mountain ranges during the Pleistocene period. However, the credibility of their theory is questionable due to existing evidence proving the contrary. The study failed to establish direct evidence to constrain valley erosion. They presumed that uplift did not occur before glaciation. However, several studies have proven otherwise.
