The lunar magma ocean volatile signature recorded in chlorine-rich glasses in KREEP basalts 15382 and 15386
chlorine fluorine Moon water glass
2017/4/10
The last liquids of the lunar magma ocean, known as urKREEP, should be highly enriched in volatiles, such as water,
fluorine, and chlorine. We find chlorine-rich glasses in two pristine KREEP basalts...
Source signature processing in deep water, Gulf of Mexico: comparison between deterministic deconvolution and phase conjugation
oversampling source signature deconvolution
2015/9/29
The Center for Marine Resources and Environmental Technology has been developing a new method to improve the resolution of high-resolution seismic profiling. To achieve this the source signature is re...
The electrical signature of rock samples exposed to hydrostatic and triaxial pressures
Electrical impedance spectroscopy fracturing carbonate amphibolite pressure
2015/9/28
The electrical signature of sedimentary (carbonate) and crystalline rock samples was studied in hydrostatic and triaxial pressure experiments up to 300 MPa. The aim was to establish a relation between...
Characterisation of the magmatic signature in gas emissions from Turrialba Volcano, Costa Rica
Volcanic gases superposition lava shallow hydrothermal system magma volcanic gases magma
2015/1/6
The equilibrium composition of volcanic gases with their magma is often overprinted by interaction with a shallow hydrothermal system. Identifying the magmatic signature of volcanic gases is critical ...
Magnetic signature of large exhumed mantle domains of the Southwest Indian Ridge – results from a deep-tow geophysical survey over 0 to 11 Ma old seafloor
Magnetic signature large exhumed mantle domains the Southwest Indian Ridge deep-tow geophysical survey 0 to 11 Ma old seafloor
2015/1/6
We investigate the magnetic signature of ultramafic seafloor in the eastern part of the Southwest Indian Ridge (SWIR). There, detachment faulting, continuous over 11 Myr, exhumed large areas of mantle...
Noble gas signature of the Late Heavy Bombardment in the Earth's atmosphere
Noble gas signature Late Heavy Bombardment Earth's atmosphere
2010/9/28
The Lunar cratering record is consistent with the occurrence of a late heavy bombardment (LHB), which marked the end of terrestrial planet accretion 3.8 billion years ago. However, clear evidence of a...
Localization of the gravity field and the signature of glacial rebound
Localization of the gravity field the signature glacial rebound
2014/4/9
The negative free-air gravity anomaly centred on Hudson Bay, Canada, shows a remarkable correlation with the location of the Laurentide ice sheet, suggesting that this gravity anomaly is the result of...
