It is important for interpretation of the seismic responses of a sedimentary basin to distinguish S and surface waves on strong-motion seismograms. A vertical array analysis method that decomposes S and surface waves from a set of surface and borehole seismic records (horizontal components) is proposed. Each of horizontal components of the array records assumed to consist of S wave and only one...

The population structure and mitochondrial (mt) DNA diversity of southern right whales (Eubalaena australis) are described from 146 individuals sampled on 4 winter calving grounds (Argentina, South Africa, Western Australia, and the New Zealand sub-Antarctic) and 2 summer feeding grounds (South Georgia and south of Western Australia). Based on a consensus region of 275 base pairs of the mtDNA c...

The block and basin tectonostratigraphic framework for the northern Pennine (rift) Basin, within which buoyant granite intrusions core intra-basin fault-bounded blocks, has long held traction. However, many of elements this are rooted in primitive tectonic models and, perhaps unsurprisingly, corresponding depositional often reflect this. Using sedimentological sedimentary provenance approaches,...

Despite the heavy regional rainfall and considerable discharge of many rivers into the Colombian Basin, there have been few detailed studies about the dilution of Caribbean Surface Water and the variability of salinity in the southwestern Caribbean. An analysis of the precipitation, evaporation and runoff in relation to the climate variability demonstrates that although the salt balance in the ...

large benthic foraminifera and dasycladalean green algae are the most common and important (micro) fossils in lower cretaceous shallow-water sediments of the tethyan realm. in this paper, we introduced such taxa and their importance in age dating of lower cretaceous strata in the kopet-dagh sedimentary basin. also, according to determinations of index taxa (fauna and flora) in this period, the ...

The term "Carlin-type" deposit has been applied to a number of low-grade, sedimentary rock-hosted gold deposits that have been discovered and brought into production in the western United States since the 1960s. Carlin-type deposits are characterized by replacement of carbonate and silty carbonate rocks by silica, pyrite, barite, various arsenic, mercury, antimony, and thallium minerals and by ...
