During the last decade, considerable progress has been made to understand the cause and nature of electromagnetic emission anomalies that precede major earthquakes1,2. Based on field measurements using a portable instrument, the preferred orientations of geogenic electromagnetic radiation (EMR), especially the principal directions of radiation have been proved to be reproducible and are related to the stress field of the lithosphere3– 6.Full Text

Dhuadhar Falls in Bhedaghat near Jabalpur, one of the most sought after tourist destinations in Madhya Pradesh, India, attracts thousands of tourists throughout the year. The mighty River Narmada drops (Figure 1 a) 30 m down into a deep gorge of marble rocks, creating one of the most beautiful natural sites. Although there is a lot of literature available describing the surrounding rocks like marbles and schists of Precambrian Mahakoshal group, Lamheta Formation of the Cretaceous and the Deccan Traps1–3, there is hardly any work explaining the genesis of the Falls itself. The River Narmada flows almost in a straight line along the Narmada–Son Lineament (NSL) marking the boundaries of some of the important basins of India4.Full Text

There are rising concerns about the robustness of interpretation from Anisotropy of Magnetic Susceptibility (AMS) studies, because often correlation between AMS and geological fabric is not properly established before a wide regional- scale interpretation is made. Here, we document case studies on two dykes from the Nandurbar–Dhule dyke swarm (western India) of Deccan Volcanic Province (Figure 1 a), where we have tested if shape-preferred orientation of the elongated mineral grains (flow fabric) is actually represented by AMS fabric. In one of the dykes, we observed that AMS fabric is coplanar with the fabric of major constituent silicate minerals; hence it represents magma flow fabric. In the other dyke, AMS fabric largely represents the shape fabric of the opaque minerals which were deposited in the interstitial spaces of the mineral grains after the dyke was emplaced; hence it does not correspond to the primary magma flow fabric. These findings reinforce the need for detailed understanding of rock fabric in order to make robust interpretation of AMS data.Full Text
