The rock formations process below the earth surface had created gaps resulting in creation of a weak zone in the Dolorite rocks. Explaining the phenomenon, Mohan Rao maintained that an inorganic compound solution had oozed out of the lithosphere. The lava substance is being sent to geological laboratory for a thorough study. –The Hindu
Decompression melting creates the ocean crust at mid-ocean ridges. It also causes volcanism in intraplate regions such as Europe, Africa and the Pacific sea floor. There, it is variously attributed either to the rise of mantle plumes (the "Plume hypothesis") or to intraplate extension (the "Plate hypothesis")

coal is organic and basically carbon, coal tar smells nice and is similarly mostly hydrocarbon and organic.

mantle plume is plausible and fits well with the also plausible expanding earth theory, which seems to be being realised and more likely than pangea theory.
extending over areas of more than a million square kilometres. Flood basalts are one type of large igneous province (LIP) that characterise the Earth's surface and have been formed at various times in the geological past - some in a submarine environment and some on land (see LIP map below). Notable examples are the Siberian Traps and the Deccan Traps (trap is a Sanskrit word meaning 'step', referring to the step-like topography produced by the stacked layers of lava). The Columbia River province featured in the above photograph is minute in comparison to the size of these enormous outpourings of lava.
If there is a causal link between flood basalt events and mass extinctions, it may lie in the environmental impact of the gases released, because basalt eruptions are not particularly explosive. Several kinds of environmental effects have been suggested, including climatic cooling from sulphuric acid aerosols, greenhouse warming from CO2 and SO2 gases, and acid rain. Basaltic magmas are often very rich in dissolved sulphur, and sulphuric acid aerosols formed from sulphur volatiles (largely SO2) are injected into the stratosphere by convective plumes rising above volcanic vents and fissures.
Flood basalt episodes have been attributed to mantle plume activity, and thus may represent one facet of a host of related global geological factors (eg, changes in sea-floor spreading rates, rifting events, increased tectonism and volcanism, sea-level variations) that tend to be correlated, and may be associated with unusual climatic and environmental fluctuations that could lead to significant faunal changes. It has also been suggested that a coincidence of both a large impact and a flood basalt eruption might be necessary in causing severe mass extinctions.

on the mantle plume link there's a location hypothesis map half way down the page, it isn't detailed but could be relevant.

this link details some recent Indian continent tectonic activity:

The estimated dates of the younger continental flood basalts compiled from recent sources are shown in Table 1. Several lines of evidence suggest that in most instances the greatest number of individual eruptions and the largest volumes of lava probably occurred within a million years or less.
