| Abstract: |
The five Archean cratons of the Indian subcontinent (Bastar, Dharwar, Bundelkhand, Singhbhum, and Aravalli) preserve various quantities of the Archean sedimentary record at low metamorphic grade; only those of the Singhbhum, the Dharwar, and, to some extent, the Bastar Craton have seen a certain degree of detailed investigation. Herein, we compile their stratigraphic and supracrustal record and attempt a synthesis comparing them to the better-known Kaapvaal Craton. The comparison particularly reveals a lack of published data from the Bundelkhand and the Aravalli cratons.
The Kaapvaal Craton has a long, well-preserved and well-described record of volcano-sedimentary, low-grade metamorphosed sequences (basins), which are separated by regional, long-lasting unconformities, regionally passing into conformities and overlapping relationships. These volcano-sedimentary successions (supergroups and local outliers) may reach several thousand meters thick, whereby those of Meso- and Neoarchean age contain world-class gold deposits (Witwatersrand Supergroup) or continuously grade into Paleoproterozoic basins, which accumulated world-class iron and manganese deposits (Transvaal Supergroup). No sequences of similar scale and stratigraphic continuity across the Archean-Proterozoic transition are known from cratonic blocks of India, except for the Singhbhum, Dharwar, and, to some extent, the Bastar Craton. More detailed geologic mapping and sedimentary facies analysis, coupled with high-resolution age dating from all Indian cratonic blocks (particularly the Bundelkhand and Aravalli cratonic blocks) is necessary to establish meaningful correlations with the Kaapvaal and other Archean cratons. |
