temporary or permanent—of cold dense MORB-eclogite sinkers (Wen and
Anderson, 1997). Cold slabs will displace the surrounding mantle, which may
melt (Fig. 2). FATE OF ECLOGITE IN THE MANTLE A series of papers (see below

Plates, Plumes, and Paradigms
Partition coefficients for eclogite have been obtained on only a subset of their full
range in composition and mineralogy (e.g., Stracke et al., 1999). Most eclogites
studied experimentally (e.g., Ito and Kennedy, 1974; Yasuda et al., 1994; Perter-

The terrain was then metamorphosed to eclogite facies during the Caledonian
Orogeny and was exposed to a temperature close to 670 C and pressure > 1500
MPa (Boundy et al., 1997) (Figure 2). During this second event, eclogites formed
...

Coesite was found also from eclogite (group II) in western Norway (Smith 1984)
and China. The occurrence of coesite in eclogite xenoliths in a kimberlite pipe
was first discovered from the Roberts Victor Mine, South Africa (Smyth & Hatton ...

Ultrahigh-pressure Metamorphism: Deep Continental Subduction
best preserved in type II lawsonite eclogite and garnet-bearing lawsonite
blueschist. Glaucophane and lawsonite containing rutile or omphacite inclusions
are interpreted to be part of this stage. The post–eclogite-stage blueschist-facies

Some investigators infer that all andesites and dacites with extreme light REE
enrichment, very high Sr/Y ratios, and low yttrium and heavy REE concentrations
formed via partial melting of subducted basalt in eclogite facies, and use the term
...
Eclogite is appreciably denser than garnet peridotite and should therefore occur
deeper in a gravitationally stable mantle. I have suggested that the Lehmann
discontinuity at 220 km is the boundary between garnet peridotite and eclogite,
and ...

The Making of a Land: Geology of Norway
Geology of Norway Ivar B. Ramberg. ECLOGITE Eclogite, the county stone of
Sogn & Fjordane, is a comparatively uncommon rock characteristically composed
of two minerals, reddish-brown to pink garnet and omphacite (green pyroxene).

Geology of Titanium-mineral Deposits
ECONOMIC PROGNOSIS The eclogite type of rutile deposit can yield hundreds
of millions of tons of ore containing up to about 6 percent rutile. The rutile
reportedly has a composition that would allow chloride processing, and it is not
too ...
