United States Geological Survey Professional Paper
Where the noritic and associated rocks are not in contact with the Magaliesberg
quartzite, they are floored by the Dull- strom volcanic formation, which overlies
the quartzite at some localities, and is the youngest of the three volcanic
formations ...

Petrological Evolution of the European Lithospheric Mantle
Gabbro- noritic veins and dykelets are formed that are rooted in the dunites and
intrude the host peridotite (Fig. 3c). These dunites are, accordingly, interpreted as
the products of reactive and focused percolation through spinel and plagioclase ...

Geological Survey of Canada, Open File 2162
In places, minor disseminated sulphides occur also in the noritic rocks overlying
the Sublayer, but elsewhere the noritic rocks do not carry any significant
quantities of sulphides (Duke and Naldrett, 1976). The relationships between the
...

The Earth's Magnetic Interior
Petrographic, geochemical and isotopic studies classify the swarms as basic-
noritic, basic and metamorphic suites (Pinese et al. 1995, 1997). The basic-noritic
swarm is the oldest with a model Sm- Nd age ∼2.65 Ga, whereas the basic and ...

Large Meteorite Impacts and Planetary Evolution II
Rapidly this compositional heterogeneity becomes stabilized through the
development of two layers, an upper "granophyric" layer and a lower "noritic"
layer, which convect independently. Once this occurs, continued melting of the
breccias of ...

Many workers (Hall & Hughes 1986, 1987, 1990a, Hall et al. 1987, Kuehner 1989
) have suggested that noritic intrusions are derived from a boninitic magma.
Srivastava (2006) studied boninitic-noritic dykes from the southern Bastar craton.
