Ultrafine - scale magnetostratigraphy of marine 1 ferromanganese crust
12 Hydrogenetic ferromanganese crusts are iron-manganese oxide chemical 13 precipitates on the seafloor that grow over periods of tens of millions of years. Their 14 secular records of chemical, mineralogical, and textural variations are archives of deep15 sea environmental changes. However, environmental reconstruction requires reliable 16 high-resolution age dating. Earlier chronological meth...
متن کاملThe crust of neutron stars
The structure of the crust of a neutron star is completely determined by the experimentally measured nuclear masses up to a density of the order of 1011 g.cm−3. At higher densities, the composition of the crust still remains uncertain, mainly due to the presence of “free” superfluid neutrons which affect the properties of the nuclear “clusters”. After briefly reviewing calculations of the equil...
متن کاملWhen the Continental Crust Melts
The continental crust is 41.4 km thick on average and covers 39% of the Earth’s surface. Information from the isotopic and trace element composition of >4-billion-yearold (Ga) zircon grains and the evolution of mantle isotopic reservoirs indicates that 75%, and possibly more, of the continental crust was created before 2.5 Ga (Harrison 2009; Belousova et al. 2010). Thus, the continental crust i...
متن کاملDurability of Neutron Star Crust
How long do neutron star mountains last? The durability of elastically deformed crust is important for neutron star physics including pulsar glitches, emission of gravitational waves from static mountains, and flares from star quakes. The durability is defined by the strength properties of the Yukawa crystals of ions, which make up the crust. In this paper we extend our previous results [Mon. N...
متن کاملContinental crust beneath southeast Iceland.
The magmatic activity (0-16 Ma) in Iceland is linked to a deep mantle plume that has been active for the past 62 My. Icelandic and northeast Atlantic basalts contain variable proportions of two enriched components, interpreted as recycled oceanic crust supplied by the plume, and subcontinental lithospheric mantle derived from the nearby continental margins. A restricted area in southeast Icelan...
