Structural Inputs of Quartz Veins on the Precambrian Basement Rocks form Ludjo, Birava, Eastern DR Congo: General Overview

Mupenge M Parfait*, Adbourahamane D Barry

The present study was made on the quartz veins of Precambrian rocks basement of the hill of Ludjo, eastern DR Congo in order to determine their preferential orientation and to compare this orientation with the different orientations of other different structures in the region. To achieve this, the field investigations were carried out with care, the veins were described; estimated vein thicknesses, and structural measurements were taken and processed for the determination of preferential orientation. The results of the research have shown that the quartz veins on the hill of Ludjo are either of micro-thickness (5-10 cm) or macro-thickness (10-20 cm). Macro-veins are most often found in quartzites which are abundant in the study area. These quartz veins exhibit an NNE-SSW preferential orientation that intersects with the Meta-Kibara formations and the quartz veins of Precambrian Numbi formations.
