In the past, interactions between the land and the sea in the southern part had initiated continental and marine deposition, creating mineral resources. Among them, coal and limestone occur in an east-west direction in Meghalaya’s south, and the coal has a high sulphur content. This is because, unlike most of the coal in India, which is deposited in the large basins of the Permo-Carboniferous age (299 to 359 million years ago), Meghalayan coal was formed in lagoons much later (50 to 33 million years ago). As a result, the coal seams are lensoidal: thick in the middle but pinching out laterally, and with a scattered distribution. And because of these reasons, it is not possible to use the same mining plan that engineers use to mine coal in other parts of the country. In other words, and professionally speaking, Meghalayan coal is not a mineable asset.
This might seem like a remote debate of little significance to most people. But names have power. There is a huge difference to the story of humanity if we are living in the Meghalayan Age that makes no mention of the human impact on the environment – or in the Anthropocene Epoch which says human actions constitute a new force of nature. The Meghalayan Age says the present is just more of the same as the past. The Anthropocene rewrites the human story, highlighting the need for planetary stewardship.
