The Namaqualand Metamorphic Complex is a well-exposed, INTRODUCTION Mesoproterozoic, low-pressure, amphibolite–granulite-facies terrane flanking the Archaean Kaapvaal Craton of southern Africa. Previous isotopic dating in the region suggests an ~150 my period of prograde granulite-facies metamorphism and episodic granite emplacement The mid-crustal granulite-facies problem in the mid-crust. In contrast, thermal modelling suggests that Granulite-facies terranes are rocks of the Earth’s lower… 
Lower crustal granulite formation during Mesoproterozoic Namaqua-Natal collisional orogenesis, southern Africa
Single-grain U-Pb zircon and monazite geochronology and whole rock Sm-Nd isotopic systematics constrain the timing of metamorphism and protolith ages for granulitic lower crustal xenoliths from the
Shrimp zircon ages and petrology of lower crustal granulite xenoliths from the letseng-la-terae kimberlite, lesotho: Further evidence for a namaqua-natal connection
Recrystallized zircons extracted from intermediate granulites of the Letseng-la-Terae Diamond Mine in northeastern Lesotho provide evidence that the Tugela Terrane of the Mesoproterozoic high-grade

A new SHRIMP U-Pb zircon age of 1091 ± 9 Ma has been acquired for the gneissic, S-type Glenmore Granite from the Margate Terrane of the Natal Metamorphic Province. The Glenmore Granite contains two
New Insights into the Geology of the Namaqua Tectonic Province, South Africa, from Ion Probe Dating of Detrital and Metamorphic Zircon
An ion microprobe study in the western part of the Namaqua‐Natal Tectonic Province of South Africa provides new insights into ages of sedimentation, magmatism, and metamorphism in the Bushmanland
Long‐lived high‐T, low‐P granulite facies metamorphism in the Arunta Region, central Australia
In situ LA–ICP–MS U–Pb monazite geochronology from the Boothby Hills in the Aileron Province, central Australia, indicates that the region records more than 80 Ma of high‐T, low‐P (HTLP) anatectic
The Aggeneys terrane is a central part of the western Namaqua Metamorphic Complex (NMC) that is most renowned for hosting world-class massive sulphide mineralisation. Peak metamorphism reached upper


Thermal History and Tectonic Setting of the Namaqualand Granulites, Southern Africa: Clues to Proterozoic Crustal Development
The Namaqualand Metamorphic Complex contains granulite facies rocks formed in two or more thermotectonic cycles during the mid-Proterozoic. The latest, most widespread and intense event at c.1150 Ma
