Magmatic rocks containing economic concentrations of iron, titanium, vanadium and
phosphorous are commonly associated with massif-type anorthosites and related rocks. This …

Compared with present-day global plate tectonics, Archaean and Palaeoproterozoic plate
tectonics may have involved faster moving, hotter plates that accumulated less sediment and …

In this paper we classify the range of feldspathic igneous rocks using five geochemical
variables: the FeO/(FeO+ MgO) ratio or Fe-index, the modified alkali–lime index, the …

The Nain Plutonic Suite (NPS), about 1.30 Ga, underlies some 19,000 km², intruding the
boundary between Middle to Late Archean rocks in the east (Nain Province) and Late …

High-resolution genetic markers have revolutionized our understanding of vertebrate mating
systems, but have so far yielded few comparable surprises about kinship in social insects …

The Rogaland anorthosite province (S. Norway) contains numerous Fe-Ti oxide deposits,
including the second most important ilmenite deposit in the world, the Tellnes deposit. The …

Experimental data in the range of 1 bar to 13 kbar enable us to map the liquidus equilibria
relevant to Proterozoic (massif) anorthosites and related mafic rocks. Massif anorthosites are …

The~ 1.74-Ga Damiao complex in the North China Craton consists of anorthosite (85%),
norite (10%), mangerite (4%) and minor troctolite (< 1%), all of which are cut by gabbroic …

The Red Mountain pluton, the youngest intrusion in the Laramie anorthosite complex, is one
of five monzonitic to granitic A-type plutons intruded at 1.43 Ga in the Laramie Mountains of …

Equilibrium melt trace element contents are calculated from Proterozoic Nain Plutonic Suite
(NPS) mafic and anorthositic cumulates, and from plagioclase and orthopyroxene …
