Episodic crustal growth in the Tanzania Craton: evidence from Nd isotope compositions

Experimental Investigation of Soapstone and Granite Rocks as Energy-Storage Materials for Concentrated Solar Power Generation and Solar Drying Technology

“…Their dominance in the composition is caused by the dominance of talc >90%, a mineral with hydrated magnesium silicate, i.e., Mg 3 Si 4 O 10 (OH) 2 . , The most dominant elements in granite samples are silicon dioxide and aluminum oxide also resembling the findings in Srivastava et al The SiO 2 content is >65% verifying that the igneous rocks UG and CG fall in the granite rocks group; this corresponds to the observation in Maqsood et al The granite rocks are peraluminous since Al 2 O 3 content is greater than the summation of Na 2 O, K 2 O, and CaO. This relationship corresponds to the granite compositions in Srivastava et al Sun et al also report on the presence of peraluminous granite in the Tanzania craton. Bouvry et al observed that high amounts of silicon oxides contribute to higher strength properties.…”

“…Biotite was marked to be common in the magmatic rocks of the Dodoma supergroup Craton. 25 The XRD images of soapstone rocks in Figure 4(c),(d) show that both rocks CS and US have peaks of talc, magnesite (MgCO 3 with iron impurities), magnesioferrite (Mg-(Fe3+) 2 O 4 ), magnetite and clinochlore ((Mg,Fe 2+ ) 5 Al(Si 3 Al) O 10 (OH) 8 ). US rock also has albite in its composition.…”

“…Muscovite and biotite are hydrothermal compounds and are thus susceptible to dehydration, causing the CG rock to be unstable at elevated temperatures. Biotite was marked to be common in the magmatic rocks of the Dodoma supergroup Craton …”

“…The Tanzanian Craton comprises the Kavirondian, Nyanzian, and Dodoma supergroups, the latter supergroup being the craton basement containing the oldest rocks . The Dodoma supergroup comprises granitoids including granite rocks accompanied by high and low grade metamorphic rocks including soapstone . The Proterozoic geo-tectonic setting is a mobile belt as opposed to the stationery craton belt .…”

“… 24 The Dodoma supergroup comprises granitoids including granite rocks accompanied by high and low grade metamorphic rocks including soapstone. 25 The Proterozoic geo-tectonic setting is a mobile belt as opposed to the stationery craton belt. 22 It is divided into three types; the Palaeoproterozoic mobile belts comprising Usagaran and Ubendian; Mesoproterozoic mobile belt of Karagwe-Ankolean, and the Neoproterozoic mobile belts of Mozambique and the Malagarasi supergroup.…”
