Quarterly slip history of the Bare Mountain fault (Nevada) from the morphology and distribution of alluvial fan deposits: comment and reply

Article Abstract:

Ferrill et al. (1996) contended that they can generate constraints on the slip history of the Bare Mountain fault other than those included in detailed field studies by examining literature and topographic maps for the age and distribution of alluvial fan sediments around the mountain. However, it is asserted that this approach is flawed because it is founded on misinterpreted data, incomplete assumptions and an unverified sedimentation model. Nevertheless, Ferrill et al. argue that their alternative analysis is useful for evaluating trenching study results.

Paleohydrogeology of the Canadian Rockies and origins of brines, Pb-Zn deposits and dolomitization in the Western Canada Sedimentary Basin: Comment and Reply

Article Abstract:

The dolomitization in the Canadian Rockies and Western Canada Sedimentary Basin originated from the input of syn- to post-Laramide orogenic fluids during the Late Cretaceous to early Tertiary age and was not caused by the flow of meteoric water. However, deltaD values of inclusion fluids from sparry dolomites reveal that the Cretaceous-Tertiary gravity-driven model for Pine Point mineralization origin is inconsistent with existing geochemical and geological research findings.

Tectonic and sediment supply control of deep rift lake turbidite systems: Lake Baisal, Russia

Article Abstract:

Lake Baikal in Russia is the world's deepest lake. It is separated by fault-controlled accommodation ridges that are 200 km long and 300 m deep. Turbidite systems developed during the late Quaternary period, mostly in the active rift basins of the lake. Research findings indicate that these turbidite systems make have been influenced by tectonic movements and that these movement caused the deposition of sediments.
