densitystructureThe Emeishan large igneous province(hereafter named by its acronym ELIP)is the first accepted large igneous region in China.The current study tries to reconstruct the density structure of the crust in this region.For this purpose,we conducted the gravity survey along an 800-km-long...
The density structure and average density of the oceanic crust have implications for various geological and geophysical problems, including interpretations of gravity data, the variation of lithospheric bouyancy in relation to age and role and fate of the crust in subduction. But no systematic evaluatio...
The stress redistribution along the brittle, velocity-weakening, part of the crust triggers the occurrence of other earthquakes, the aftershocks. They follow well established empirical laws that can be put in the form of power laws with quite universal values for the exponents2. In particular, ...
and also byAdamia et al., 1980,Adamia et al., 1991,Yılmaz et al. (2010), it is possible to infer the thickness of the crust, density of the rocks,seismic velocityand inclusions with velocity along the geotraverse. The designed cross-sections are the interpretations of these ...
how much pressure may be put upon water its volume is little decreased and its density little changed. So it happens that substances which readily sink in the upper part of the sea sink to the bottom no matter how deep the water may be, as the bottom is so little denser than the top...
In fact aluminum is famous for not occurring natively: Despite being the third most abundant element in the earth's crust, accounting for over 8% of the total weight of the crust, it was completely unknown as a metal until 1825 when small, precious samples were first isolated from ore. ...
whereg0is the mean surface gravity,athe mean Earth’s radius,ρthe mean density of the crust, andGthe gravitational constant. The first term in right hand side of Eq.1is usually called the free air correction and amounts to about – 0.31 μGal/mm; the second term is the effect of an...

density model via 3D inversion18,19. The density cross-section was extracted from the final inverted 3D density model to match the seismic transect (Fig.2C). An isosurface was extracted using the density contrast value of 0.07 g/cm3(Fig.S2). At the southern margin of the density section,...
39. Characteristics of Water. Experiment 35. —Place in a dish of fresh water a density hydrometer, or stick loaded with lead at one end, so that it will float upright. Mark with a rubber band the point to which the hydrometer sinks in the water. In a dish sufficiently deep for the ...
