From the foreword: "The Son and Narmada rivers, flowing respectively east and westward from the Amarkantak plateau in Madhya Pradesh, together follow a striking linear feature which extends across the Indian sub-continent from Saurashtra coast to Chotanagpur plateau of Bihar and possibly further east. This lineament is believed to mark the boundary between two regimes of contrasting geological (magmatic, tectonic and sedimentary) history. This feature has received the attention of geoscientists since the middle of nineteenth century and the debate is still on whether the Son-Narmada linearity is a geomorphological coincidence of erosional valleys or a deep structural feature signifying a continental rift."
