“…The Group 2 dyke samples show a good geochemical correlation with the NW–SE to WNW–ESE trending 2.21 Ga Anantapur‐Kunigal swarm (earlier known as Kunigal swarm by Srivastava et al, ; see Figures b and b) and NW–SE to WNW–ESE trending 2.18 Ga Mahbubnagar–Dandeli swarm (earlier known as Mahbubnagar swarm by Srivastava et al, ; see Figures c and c); however, dyke trends of these two swarms are not similar (cf. Samal et al, ; Söderlund et al, ; see Figure ). Therefore, it is not appropriate to considered them co‐genetic.…”

“…Based on new U–Pb ages together with previously published precise ages on the mafic dykes, Söderlund et al () have identified eight generations of Palaeoproterozoic dyke swarms within the 2.37–1.79 Ga age interval from the Dharwar Craton. These include (a) NE–SW to ESE–WNW trending ~ 2.37 Ga Bangalore–Karimnagar swarm, (b) N–S to NNE–SSW trending ~ 2.25 Ga Ippaguda–Dhiburahalli swarm, (c) N–S to NNW–SSE trending ~ 2.22 Ga Kandlamadugu swarm, (d) NW–SE to WNW–ESE trending ~ 2.21 Ga Anantapur–Kunigal swarm, (e) NW–SE to WNW–ESE trending ~ 2.18 Ga Mahbubnagar–Dandeli swarm, (f) N–S, NW–SE, and NE–SW trending ~ 2.08 Ga Devarabanda swarm, (g) E–W trending ~ 1.88–1.89 Ga Hampi swarm, (h) NW–SE ~ 1.79 Ga Pebbair swarm.…”
