The Bangweulu Block is a cratonic unit that forms part of the Congo craton of central Africa. The Bangweulu Block however consists of Palaeoproterozoic granitoids and volcanics, and is overlain by a Palaeoproterozoic continental sedimentary succession, the Mporokoso Group, and does not preserve much direct evidence of Archaean protoliths.
Indirect evidence of an Archaean ancestry for the Bangweulu Block is provided by detrital zircons within the Mporokoso Group, which indicate a local source area with zircons of 3.2, 3.0. 2.7 and 2.5 Ga, but more importantly, by xenocrystic zircon found in volcanic and granitic lithologies of the Bangweulu Block, and the area to the West, the Central African Copperbelt (Rainaud et al., 2003), which indicate the presence of a ca. 3.2 Ga terrane called the Likasi Terrane.
Famous quotes containing the word block:
“It is, in both cases, that a spiritual life has been imparted to nature; that the solid seeming block of matter has been pervaded and dissolved by a thought; that this feeble human being has penetrated the vast masses of nature with an informing soul, and recognised itself in their harmony, that is, seized their law. In physics, when this is attained, the memory disburthens itself of its cumbrous catalogues of particulars, and carries centuries of observation in a single formula.”
—Ralph Waldo Emerson (1803–1882)
