Abstract

The structural pattern of Delhi system of rocks around Dariba is dominated by open, asymmetrical folds which occur on both major and minor scales. A set of axial plane cleavages, which grades from discrete fractures to slaty cleavage, is consistently developed with the folds. The axial traces of the major fold range in trend from NNE-SSW to WNW-ESE. Although the fold axes vary both in direction and amount of plunge, the axial planes are consistently inclined westwards. The copper ore bodies which have been explored so far, occur in the eastern ridge of Dariba. Mineralisation is practically confined to phyllites ana schists. The lenticular ore bodies have been explored uptil now on the limbs of major overturned synformal fold in the eastern ridge. The axial plane cleavage has been observed to be the main structural plane controlling the distribution of the disseminated sulphides in the rock.
