Hirapur is mainly known in India and elsewhere for its phosphorite reserves preserved exclusively in fine ferruginous clastic facies of Palaeoproterozoic age. These rocks belong to the Bijawar Group and have been mapped several times by the Geological Survey of India and others along with the granitic basement. In some of the maps, granites have been shown to be intersected by basic dykes, yet post-Bijawar dykes have not been mapped so far. Here, we present an updated map of the Hirapur and the adjoining areas where the post-Bijawar dykes are mapped.

摘要

Hirapur is mainly known in India and elsewhere for its phosphorite reserves preserved exclusively in fine ferruginous clastic facies of Palaeoproterozoic age. These rocks belong to the Bijawar Group and have been mapped several times by the Geological Survey of India and others along with the granitic basement. In some of the maps, granites have been shown to be intersected by basic dykes, yet post-Bijawar dykes have not been mapped so far. Here, we present an updated map of the Hirapur and the adjoining areas where the post-Bijawar dykes are mapped.
