Rhyolite lavas and xenoliths from the Salton Sea geothermal field (Southern California) provide insights into crustal compositions and processes during continental rupture and incipient formation of oceanic crust. Salton Buttes rhyolite lavas contain xenoliths that include granophyres, fine-grained altered rhyolites (“felsite”), and amphibole-bearing basalts. Zircon is present in lavas and xeno...

It is important for human society to continuously monitor the sea level, since more than 50% of the world’s population live within 60 km of the coast [1]. Moreover, global climate change is believed to result in the melting of large masses of ice in Polar Regions. This will bring freshwater into the ocean [2] and thus change the sea level [3]. The traditional way to observe sea level is with ti...

In the process of continuous casting, the melted steel from the melting pot is passed, through the intermediary of the distributor, in the water-cooled crystallizer tank. In this way, a crust forms here which is solidified at the exterior, and one of the great problems is its cracking or even its tearing, due to several factors. This phenomenon determines the stopping of the technologic process...

The initial isotopic compositions of Nd and Sr in basalts from the Central Siberian Plateau and other major continental flood basalts are reported. The continental flood basalts appear to be the product of partial melting of mantle sources that consist of relatively primitive undifferentiated material and are clearly distinct from midocean ridge basalts, which sample mantle reservoirs that have...

The combination of UPb zircon ages with Hf-Sr-Pb isotopes different intrusive and extrusive felsic sedimentary rocks provides constraints on the petrogenetic evolution continental crust in western Dharwar Craton, India. oldest detrital preserved formed at ?3.6 Ga represents a relic crustal material region. dominant granitoid units Craton contain grains magmatic between 3.4 3.0 that indicate for...
