Lacustrine deposit...... it's not shield rock.
The fastest isostatic rebound is experienced on the Island of Igloolik. Your internet intellect falls short of reality. CM "Bob Crantz" wrote in message link.net... http://www.state.nd.us/ndgs/Rebound/...%20Rebound.htm Says: "The greatest measured rates of isostatic or postglacial rebound in North America occur in the Richmond Gulf area of southeastern Hudson Bay (presumably where the ice was thickest). There, a kind of "staircase" of 185 Holocene (postglacial) strandlines (former shorelines) provide a continuous record of emergence from about 8,000 years ago until the present. At least 935 feet of recovery (isostatic rebound) has been recorded by these strandlines. By determining the age of these strand lines, and by subtracting the apparent component of uplift due to relative sea level fluctuations, geologists have been able to measure rates of isostatic rebound. The rates of uplift have declined from a maximum of 33 to 39 feet per 100 years immediately following deglaciation (8,000 years ago at Hudson Bay - in North Dakota deglaciation occurred about 5,000 years earlier) to a current rate of about 4.3 feet/100 years. In other words, the shoreline at Churchill, Manitoba on the shore of Hudson Bay is currently rising about 4.3 feet per century." Not only are you remarkably wrong in your statements, the fastest North American rebound on record is right under your own two feet! And you've shot both of them! You are not even a barstool geologist! The only rocks you've ever encountered are in your head! Is that enough of a beating or do you want some more? Amen! Bob Crantz "Overproof" wrote in message news:PBKAd.35229$dv1.16823@edtnps89... Isostatic rebound is not uniform.... it is the result of removal of pressure from Glacial encroachment. It is entirely subject to underlying geomorphology No accurate data exists beyond about 50 years ago.... the data is interpolated from archeological investigation is based on proximity to water of ancient campsites. The Laurentian Shield is not undergoing isostatic rebound at the rate you posted. If this were so...... we could buy sea frontage and expect our investment to gain a meter every hundred years. I can assure you nobody has reported such gains in the last 3 centuries. The mid Atlantic Ridge is the opposing the subduction of the Pacific plates. Now cry to your God about how unfair life is and that Creationism is still a viable explanation of mankind's evolution. Fanatics!... Phffft! CM "Bob Crantz" wrote in message link.net... You fool! The isostatic rebound of the Laurentian Shield is quoted as 1-2 cm/yr: http://travesti.eps.mcgill.ca/~olivi...es/node43.html Plus there's other rebounds of at least 2 inches per year!

I just love it when they start researching on the internet...... when they
find something to back their argument it's a factual statement.... when it fails to back their claims it's just more internet crap. BTW - I'm not a Geologist... I'm a Geotechnical Technician. CM "Scout" wrote in message ... ROFLMAO - Ya gotta just love it when the debate gets around to this! For my money, there's never been a funnier line. "Bob Crantz" wrote: You fool! |

That seems a whole lot more plausible Peter. Plate subduction can be extreme
at times of failure..... but what will be most interesting is the cause of the massive plate movement in the first place. Tectonic Plate subduction is the primary cause of "Earthquakes" as well as volcanic formations. Fault line slip is not the culprit... it's the weakpoint effected by amassing pressure due to tectonic plate movement. I'm certain our lovable Bible Toting Bob will provide us with further proof that his assumptions as researched on the internet are correct...... even though he should admit it was God's Will that this occurred. Next thing we know he'll be questioning "Creationism" CM "Aniculapeter" wrote in message ... I just read in today's paper that the source seems to be Ken Hudnut from the US-GS. He has been quoted for saying something like: "The earthquake changed the world map" "Small islands in the Indian Ocean has been moved up to 20 meters, while the north-western tip of Sumatra may have moved up to 36 meter." (my translation from the Danish translation). Erik Schou Jensen, from The Geological Museum at the University of Copenhagen, thinks that Ken Hudnut has been misquoted, and says: "What he (KH) is talking about, is a small splinter (?) of a plate located on the sea-bottom north of Sumatra. This, he (KH) thinks, can have moved up to 36 meter" "It has not been possible to perform the necessary measurements, since the Indonesian authorities has closed the whole area down (?) but the island can have moved a few centimeters..." "During the earthquake, it was the Indian plate that slid down under the plate with Sumatra, so it would not have been Sumatra that moved, but the sea-bottom under the Indian ocean and not more than five to six meter at one time." So it looks like it was just another example of the press not being able to present the facts. Peter S/Y Anicula Overproof skrev i en nyhedsmeddelelse:SBHAd.24735$Y72.23238@edtnps91...

"Bob Crantz" wrote in message The Himalayas grow about 1 meter every 100 years as the result of relative movement of tectonic plates. Amen! Bwahahahahahahaaaaa........ Yeah Bob.... India absorbs almost nothing in regards to plate movement..... it's all miraculously transferred to foliating the gneiss of the Himalayas a thousand miles inland! Next you'll be preaching to me how God formed the Rockies! CM |

How about relevant to the established datum... at the time that data was
collected.... and the accuracy of the equipment utilized to derive it. BTW - Lots of people disagree with me.... none that count though. CM "Bob Crantz" wrote in message k.net... http://www.nation.com.pk/daily/dec-2004/29/index2.php Two USGS PhD's seem to disagree with you. Remember, movement is relative - relative to what? |

There, a kind of "staircase" of 185 Holocene (postglacial) strandlines (former shorelines) provide a continuous record of emergence from about 8,000 years ago until the present.

At least 935 feet of recovery (isostatic rebound) has been recorded by these strandlines. By determining the age of these strand lines, and by subtracting the apparent component of uplift due to relative sea level fluctuations, geologists have been able to measure rates of isostatic rebound.

Again ... the local geomorphology has a lot to do with the rate of rebound.

I haven't You are not even a barstool geologist! The only rocks you've ever encountered are in your head! You are mistaken..... I've been involved in a detailed reasearch on the geology of the Northwest Territories.. specifically Glacial Lake McConnell, it's beach ridge deposits and limits of lacustrine impact as well as the Moraine, Alluvial formations. I've worked with Petroleum Geologists and Geological Engineers. Is that enough of a beating or do you want some more? Bring it on Bob.... your current stance on evolution will anger your God when he realizes that you do not believe him to be responsible for such action. Seriously Bob... how can anyone lend credence to an argument of scientific nature presented by someone who believes in "Creationism"??? CM |

You can attack me or my sources all you want. But you can't refute a single
fact. The bottom line is you said isostatic rebound is never more than a few cm/100 yrs. I've found numerous references that show otherwise by a large factor. Every challenge you presented I've met with data published by geologists at Universities. All you've done is reduce the scope of your statement or added qualifications. The bottom line is your statement of fact is wrong. The statement of fact is not altered by your summer job or any other consideration about you. The facts are proven by reality, not the colour of your socks. You've received an efficient and thorough beating from me and you've learned something too, so you won't look so ridiculous staggering around the bar up north next summer. You should thank me. On more note, you won't be going to the lava lakes when you expire. God does not send retards to hell, he has a special place in heaven for people like you. Here, on earth, you are an embarrassment to all who drool. Next time try taking your beating like a man. You'll look less foolish. Amen!

I see you here administering a severe beating to CM with your every post. Who says men of the cloth are narrow-minded and ignorant? You, sir, prove otherwise with your every erudite, factual and insightful post. Your grasp of the physical world is ever so much worldly than a certain, drunken, Nova Scotia, neophyte sailor's ever will be. In spite of being soundly pummeled about the head and shoulders, I see CM remains in total denial. How is it some folks can't seem to accept reality, admit their mistakes and step out of the pyre that consumes them? Could it be they are so possessed by Lucifer that they have come to enjoy ignorance and pain? Surely such as CM will have their immortal souls reincarnated in canine form so they will have two more feet to chew off when they get caught in the inevitable bear trap of their own stupidity.
