Where on Google Earth # 194

WoGE 194 I have chosen based on the striking convergence of interesting features. I was extremely lucky in finding Ron's WoGE 193 of Mount Usu, knowing immediately where the volcano was located due to just helping my brother-in-law research for a report on various volcanoes over the weekend. That shows how mentoring can pay off for both parties! I'm going to hopefully keep the pace of discovery moving and not invoke the Schott Rule for this feature. Boa Sorte

Got it!

PL means Peter L, I just didn't find a better way to sign in...

I am not sure if I can do this geological splendour much justice, since I am just a mere geophysicist sitting in my lab all day and never touching rocks.

I would presume this is somewhat similar to the fold-thrust-belts found in the Zagros mountains. So what we see in that oval thing is actually the top of the stratigraphic sequence, not the bottom. Furthermore we can spot weird looking salt flats in the top-right corner.

I probably missed 90% of the geology here and would love to see a proper geologist fill in the rest ^^

Oh, I am not the only one, hi Peter :)

Who's next? I was a little quicker but you had more precise explanation faster at hand. Guess that kinda makes it even.

Stryke, as you'd figure, it takes a little time to dig up some geology beyond the obvious... I don't mind making this a tie (and am happy to leave you posting #195), but keep in mind that you're not supposed to post location w/o geological description. I found necessary to stress out this rule in some of my earlier WoGE posts, as this kind of things already happened before.

Dang, too late! Anyways, I found out quite a bit while researching this location. I was only aware of its general location because I had studied the Deccan Traps last semester. Anyhow, this would have been my triumphant post had I been here 5 hours ago!

What we have here is a snapshot of the Makran Coast Range in southeast Pakistan, rotated almost 180 degrees (sneaky!). At first glance, the eye is drawn to the ridge and elliptical structure just south of it (not sure if it's a basin or a dome complex). In the upper right corner (SW) there are what look like longitudinal dunes, and on the bottom (N) of the image there appear to be some ancient river systems (most likely part of the Indus system at some point long ago).

This region is part of what is known as the Makran Accretionary Prism (or Wedge), caused by the subduction of part of the Arabian plate under the Eurasian plate. Page 41 of "The Tectonic and Climatic Evolution of the Arabian Sea Region" (google books) has an image that illustrates this quite nicely.

That was a good one!
Cheers,

Michael

Very true, Peter. I figured that since no one came up with anything in 4 hours, I could post the locality first and write something about the geology immediately after. Finding information on this turned out to be quite hard. Sorry about that, I'll make sure I have a short explanation at hand next time (or even a brilliant one, such as Mike's) :D

I'd like to declare Peter as the winner, since I didnt even get the accretionary prism (shame on me).

I have a neat but insanely hard new WoGE spot tho... :D

Dominion: It seems to me you've forgotten to announce this post on Ron's WoGE#193 comment list (as it is customary in this game). I bet there still are WoGE folks checking Ron's blog for your #194 announcement (for me, bumping into your puzzle was a matter of sheer luck).

Stryke: This is not the first tie win in the WoGE history. So I'd suggest go ahead and post your insanely tough spot, and drop a link here when it's up. It would be nice if you'd place a comment containing a link to your WoGE#195 to Ron Schott's WoGE#193, too.

Ron Schott said...

For what its worth, there is precedent on near simultaneous entries - the first person to submit the correct coordinates (presuming they later submit a geological explanation) has previously been awarded the subsequent WoGE. In this case that would seem to be Stryke.

WoGE 195 is slated for autopost at 10 PM New York EDT, 2 AM UTC (imagine dramatic 24 music, tic toc tic toc tic toc!)

It will appear here:

hopefully.

Cheers!

Sorry I didn't post an announcement, and even get back in time to crown a winner. Excellent work everyone.
