Quartz veins and shear zones occur in a Palaeoproterozoic cratonic-margin setting.
Tanzania gold geology
Public previewUbendian Belt / cratonic margin
Lupa–Chunya Goldfield
The Lupa Goldfield lies at the southwestern margin of the Tanzania Craton in the Ubendian Belt. Academic work describes Palaeoproterozoic orogenic gold in auriferous quartz veins and brittle–ductile to mylonitic shear zones, with a long history of structural reactivation. This setting should not be collapsed into the Archaean Lake Victoria greenstone model.
Updated: 2026-08-13
Long-lived structural weaknesses may record more than one mineralising or remobilisation event.
Age and structural context distinguish Lupa from Lake Victoria district models.
Report overview
01
Geological and chronological setting
Research places the goldfield at the cratonic margin within the NW–SE-trending Ubendian Belt. Archaean granitoid basement and Palaeoproterozoic felsic–mafic intrusions were affected by later metamorphism and deformation.
Goldfield-wide mineralisation is linked in published work to a Palaeoproterozoic orogenic event around 1.88 Ga. The date is a regional research result, not an automatic age assignment for every vein.
