 |
|
There is a 40' diameter bullseye-like rock formation at the base of a
mountain above the Lehigh river. The rock looks like it is folded in
many concentric layers. There appears to be two or three different
kinds of rock in this anamoly. Nothing like it can be seen nearby.
Can someone please share with how this could be formed? If
interested, I do have a picture to send. |

If you do send it in, include a google Earth coordinate too (bottom

Would like to see the pic. Try to post to a link site or an upload
site. If its just one pic, then maybe post it here. |

I concur. The top of a folded layer of rocks.
Rocks get laid down flat. Later, continents mash into the rocks, folding
them up. Sometimes the rocks are still only semi-solid (like playdough)
sometimes they are totally rock but still can be warped under steady,
constant intense pressure.
That part of PA is noted for such things.

I grew up near Reading, about an hour southwest of there. The whole
anthracite coal belt from northeast of Harrisburg to the Delaware
water gap is made up (mostly) of Paleozoic rocks - shales and
limestones. As Mr. Schaper pointed out, these rocks are strongly
folded, sometimes through several generations (folds that are
folded). A geologic map of the area or a satellite view reflects this
dramatically.
I suspect the rock itself is a limestone, but I could be wrong. If
you break it open and put hydrochloric acid on it and it fizzes
(bubbles), it is most likely a limestone.

....Like Continent India collided with Continent Asia to mash/ crumple
up the Himalayas. That right Jo? You can see the crumpling and the
folding everywhere this happens
http://users.indigo.net.au/don/to/evrev.html
In fact, you can confirm it right here:-
------------------------------------------------------
Understanding plate motions [This Dynamic Earth, USGS]
"The Himalayan mountain range dramatically demonstrates one of the
most visible and spectacular consequences of plate tectonics. When two
continents meet head-on, neither is subducted because the continental
rocks are relatively light and, like two colliding icebergs, resist
downward motion. Instead, the crust tends to buckle and be pushed
upward or sideways. The collision of India into Asia 50 million years
ago caused the Eurasian Plate to crumple up and override the Indian
Plate."

It>s noted for more than that. Back t>yore knittin' , gran>maw. (till
the children come Tuesday, you can look out the playdo and teach them
a thing or two. )
Christ Jo! .. you>ve learned nothing, ..except that it>s judicious to
stick with the tosser-dosser in-crowd. Well, at least if it gets
articles published, .. I guess. And that, I suppose is the point you
will teach them. GowiththefloJo) ... gowiththeflo.
Well there>s certainly pay-off in that. Only a fool says otherwise.
In fact there>s real money to be made in it, when fools are willing to
give you. And what can be wrong with that? Nothing that I can see.
("The gift that keeps on giving.. .." )
Gee whizz. And that>s just when it comes to the hat-magic that the
Earth Sciences peddles. What then, when it comes to more onerous
things, ..Like should children be allowed to beat up other children in
the playground. And if not why not. Why shouldn>t the strong and the
bullies win? Even if they *are* intellectual bullies. I bet you>d
have been in the front row watching all those bastards burn, the
Church told you were bad people.
(Yup, ..we always end up with Adolph. He knew he was on to something.)
(and he was right.) (about people) Some take the view they need
protected against their excesses, ..but he *knew* there was advantage
in encouraging them. Just watch those children on Tuesday and the
lesson you teach them with your playdo. They>ll use it against you
one day. (knowing what children are like...) |
