in this paper, the effect of bedrock inclination on seismic performance of slopes is investigated. the study was conducted based on dynamic analysis of different slopes, evaluation of the earthquake acceleration in sliding mass, and calculating the permanent displacement of the slope, using newmark sliding block. the investigation indicates that variation of the bedrock inclination may cause th...

taposed along the north-trending, high-angle Nahlin fault; all three tectonic elements are intruded by the Late Cretaceous Atlin Mountain pluton (Figure 1-19-2). The oldest rocks in the eastern domain are Mississippian to Triassic oceanic; crustal and sedimentary rocks of the Cache Creek Complex. These include ultramafite, basalt, limestone, chert, argillite and wacke, and probably a mixed ultr...

Olivine chemistry as a petrogenetic indicator for origin and formation conditions of Sargaz-Abshur ultramafic-mafic intrusion, SE Baft, Kerman

The age and origin of the quartz-amphibole-pyroxene (qap) gneiss from the island of Akilia, southern West Greenland, have been the subject of intense debate since the light C-isotope composition of graphite inclusions in apatite was interpreted to indicate the presence of Earth's earliest biological activity. Although this claim for biogenic relicts has been vigorously challenged, the possibili...

A new species of skink, Caledoniscincus notialis sp. nov., is described from the ultramafic ranges in southern New Caledonia. It is most similar to, and has previously been referred to Caledoniscincus atropunctatus (Roux), a species with a widespread distribution throughout the Grand Terre and Loyalty Islands. The new species is distinct genetically from all other Caledoniscincus and can be dis...

Particle transport by erosion from ultramafic lands in pristine tropical lagoons is a crucial problem, especially for the benthic and pelagic biodiversity associated with coral reefs. Satellite imagery is useful for assessing particle transport from land to sea. However, in the oligotrophic and shallow waters of tropical lagoons, the bottom reflection of downwelling light usually hampers the us...
