First Direct Evidence of Pan-African Orogeny Associated with Gondwana Assembly in the Cathaysia Block of Southern China [PDF]
Scientific Reports, 2017 Metamorphic zircon from a hornblendite in the South China Block (SCB) yield U-Pb age of 533 ± 7 Ma and Hf model ages from 900 to 1200 Ma. Geochemical and isotopic characteristics indicate that primary magma of the hornblendites was probably derived from ...

P-T conditions of Pan-African orogeny in southeastern Nigeria [PDF]
Central European Geology, 2008 Abstract Different rock types from the area northeast of Obudu, southeastern Nigeria were investigated in order to place constraints on their metamorphic conditions. Detailed petrographic studies indicate four main rock groups in the studied area, namely migmatitic gneiss, migmatitic schist, granite gneiss and a minor amount of amphibolite, metagabbro ...

Decratonization by rifting enables orogenic reworking and transcurrent dispersal of old terranes in NE Brazil [PDF]
Scientific Reports, 2021 Dispersion and deformation of cratonic fragments within orogens require weakening of the craton margins in a process of decratonization. The orogenic Borborema Province, in NE Brazil, is one of several Brasiliano/Pan-African late Neoproterozoic orogens ...

Seismic signatures of the Pan-African orogeny: implications for southern Indian high-grade terranes [PDF]
Geophysical Journal International, 2009 We present the results of a study designed to investigate and compare the seismic characteristics of the once contiguous terranes of eastern Gondwanaland, now incorporated in five separated continental masses, which, during the Neoproterozoic (223C600 Ma) Pan-African orogeny, suffered a high degree of thermal stress and deformation.

Landsat-8 OLI/SRTM and gravity characteristics of the Pan-African fracture aquifers of the north central Cameroon region (central Africa) [PDF]
HeliyonFinding drinking water in a Precambrian (Pan-African) basement context is a major concern for many Central African countries. For example, most groundwater is in fissured or fractured basement aquifers.
