Where On Google Earth #485

On the heels of a tough WOGE #482, Ole took us to Mistaken Point, Newfoundland, in WOGE #484 for a look at the extraordinary fossils found there—some of the oldest complex life known anywhere on the planet.

Here is WOGE 485. I think there should be enough clues in this one to make it fairly fast.

Find the location of the image in Google Earth, and leave a comment with the latitude and longitude with a brief description of the geology/geography/hydrology of the area. The first person to identify it correctly will host the next WOGE (you can ask a regular to host it for you if you don’t have a blog for it).

  1. “.. It all happened nearly 70 million years back.. The mighty Himalayas were just beginning to come up, the great dinosaurs that ruled the earth were disappearing and the crust of the earth in the Western India was fractured. This was a remarkable event – large quantities of molten rock (Lava) were poured out from these fractures filling up valleys and covering the hills. The eruption continued intermittently with periods of quiescence, building up a huge volcanic province…” (West, W.D. 1988)
    17.54°N 73.91°E – Mahabaleshwar, India – One of the places to see the typical “Trappean” topography of the Deccan Plateau!

    The geological world identifies this volcanic province either as the “Deccan Volcanic Province” (DVP) or simply the “Deccan Traps” and recognizes it as one of the Large Igneous Provinces (LIPs) representing high magmatic fluxes involving large amount of thermal energy in short period of geological time. The term “Deccan Trap” was coined by W.H. Sykes in 1833 and it is derived from a Sanskrit word Dakshin meaning south or southern and a Swedish word Trapp/ Trappa meaning Stair. The term was aimed to describe the step like or terrace like topography peculiar to this terrain. (source)

    The Deccan traps, (…), cover almost the whole of the district and constitute the innumerable rugged and bold, flat-topped hills, forming extensive plateaux of the entire Western Ghats. They also constitute the small hill ranges in the eastern and central parts of the district. Besides, lava flows also blanket the plains with a soil covering of varied thickness. (source)

    It’s an area rich in basalts an “All of these basalts are silica-saturated tholeiittes; and the series shows minor gradual variation with the order of eruption.” (source)

    Also, Mahabaleshwar is the source of the Krishna River that flows across Maharashtra, Karnataka, Telangana and Andhra Pradeshis flowing into the Bay of Bengal.


  2. That’s it!

    Unlike the previous WOGE (linked at top of post), there are no fossils here. Also, despite the volcanic nature of the Deccan Traps, there are few high-precision radio-isotopic dates, due to the intense weathering and alteration from the tropical climate.

    With an age similar to that of the Cretaceous-Paleogene extinction, there is some research being done to test for a link between the Chixulub impact event and Deccan Traps volcanism.

    Better geochronology for the Deccan Traps could show whether the volcanism came mainly before, during, or significantly after the impact and extinction. Whether much the huge volume of magma (area of California 1-3 km deep) erupted in 2 Ma or 150 ka makes a big difference for calculating climate impacts and comparing the timing with extinctions seen in the marine and terrestrial fossil records.
