The area of northeastern Zambia, between Chama and Lundazi towns, is underlain by rocks belonging to the Irumide Fold Belt, a Mesoproterozoic orogenic belt whose geology is dominated by biotite gneisses, which often show incipient migmatisation, that belong to the Kampemba Group. Less common...

In the Chisamba area, some lithologies hitherto mapped as quartzites and dolomitic marbles are quartz mylonites and interbanded calc-silicate, marble and amphibolites, respectively. Both meso-and microstructural fabrics in the Chisamba area indicate that deformation associated with shearing was...
Download PDF ↓The syenites and quartz feldspar porphyries of the Mumbwa district occur as satellite bodies at the north east margin of the Hook Granite Massif, a large batholith dated 456 Ma, and intrude the pre-Cambrian Katanga metasediments. The composition of syenitic rocks varies from hornblende biotite...

The distribution of As, Cu, Zn, Fe and Mn in different size fractions of both sorted and ur.sorted stream sediments were investigated and compared to bedrock and soil...
Download PDF ↓Syenitic rocks in Eastern Zambia are represented by both oversaturated quartz bearing types and undersaturated nepholine-sodalite varieties.The ,Sinda syenite intrusions are oversaturated potassics which form a petrogenetically related N-S trending string of intrusions at the eastern margin of...
Download PDF ↓Calc-silicate rocks and marbles of Katangan age underlie a significant segment of the Zambezi belt in Southern Province. The calcsilicate rocks are represented by spectacularly banded calc-silicate gneisses, calc-silicate schists, massive calc-silicate rocks and a few mottled varieties. The...
