[1] The water solubility in pyrope-rich garnet was determined between pressures of 5–9 GPa and temperatures of 1373– 1473 K under silica activity and oxygen fugacity similar to those expected in the Earth’s upper mantle. We found that pyrope-rich garnet has substantial water solubility up to 0.1 wt% under these conditions. In addition, the water content in garnet varied as a function of chemica...

Minerals recovered from the deep mantle provide a rare glimpse into deep Earth processes. We report the first discovery of ferric iron-rich majoritic garnet found as inclusions in a host garnet within an eclogite xenolith originating in the deep mantle. The composition of the host garnet indicates an ultrahigh-pressure metamorphic origin, probably at a depth of ~200 km. More importantly, the fe...

In Cameroon, most of the iron formation occurrences reported are found within Nyong and Ntem Complexes. The Anyouzok deposit is located in Complex greenstone belts, which represent NW margin this Congo craton. main lithological units comprise formations (IFs) unit, consisting banded IFs (BIFs) sheared BIFs (SBIFs), associated metavolcanic rocks unit mafic granulite, garnet amphibolite, biotite ...

The 465 Ma Svarthopen pluton in northcentral Norway was emplaced under middle-crustal conditions (~700 MPa) into metasedimentary rocks of the Helgeland Nappe Complex. The pluton is characterized by zones of mingling and mixing of gabbro/ diorite with peraluminous, garnet-bearing biotite granite. Variation in bulk-rock Sr and Nd isotope ratios are consistent with simple mixing; however, nonunifo...

Introduction: The presence of garnet in the lunar mantle has been debated from many years (e.g., [1-3]). Data from the Apollo seismic network were unable to unambiguously resolve a garnet signature in the lower mantle. For example, higher seismic velocities in the lunar mantle (>500 km) could be indicative of an increased proportion of Mg-rich olivine [2,4], or be due to the presence of garnet ...

This paper presents Garnet, a novel spatial hypertext interface to a digital library. Garnet supports both information structuring – via spatial hypertext – and traditional information seeking – via a digital library. A user study of Garnet is reported, together with an analysis of how the organizing work done by users in a spatial hypertext workspace could support later information seeking. Th...

In 1975, Social Security beneficiaries were given the option of having their monthly benefit payments sent directly to their banks through an electronic funds transfer system. Since then, beneficiaries have been enrolling in this program in rapidly increasing numbers. At the end of 1976, fewer than 5 million beneficiaries--14 percent of the total--were enrolled in the program. By the end of 198...
