Himalayas ... how fast did they rise?

Himalayas ... how fast did they rise? · Himalayas, bis ... and Pyrenees · ter · quater · quinquies ... double-checked

I bought a booklet in the collection "que sais-je?" about this. That is, about the Himalayas, only first short chapter involving "millions of years" - the rest being presumably fairly accurate. L'Himalâya, Jacques Dupuis.

Now, according to this booklet, Himalayas rose mainly after Cretaceous. I look for another source, and yes, Indian landmass is supposed to have started moving 71 million years ago, and the collision to have happened 55 million years ago. It would have ended at the onset of the Pleistocene, according to uniformitarians starting 2.5 million years ago. This leaves 52.5 million years for a rise of - for Mount Everest - theoretically 11 000 meters, but in fact, due to ongoing erosion, only 9000 meters.

8848 meters. This means 1152 meters eroded in 2.5 million years.

1 152 000 mm : 2 500 000 years = 0.461 mm per year.

During the rise, 2000 meters eroded in 52.5 million years, since it ended at 9000 instead of 11 000 meters.

2 000 000 mm : 52 500 000 years = 0.038 mm per year.

How come erosion changed speed so much? I mean, it was not a question of actual lowering, since it is about an erosion that compensates a much bigger rise ...

How much would the rise have been, by the way? I'll be unrealistic and have it start out a 0 meters ... now, this means a rise of 11 000 meters in 52.5 million years.

11 000 000 mm : 52 500 000 years = 0.00021 mm or 0.21 μm per year.

Maybe that is supposed to be realistic if you suppose that it was all solid before getting to collide and rise.

I suppose, on the contrary, the Himalayas rose after the Flood, with the added verticality as part of God's way to drain flood waters down into deep sea basins and generally oceans, unless one takes the wind drying around the landing place (Genesis 8 verses 1 and 14) as applying to all of the earth, equally.

This means, they started rising in 2957 BC, the year of the Flood. I'll not suppose Mount Everest was higher or would have risen 2000 meters higher. I'll suppose also that Himalayas were in place by ... Exodus, perhaps birth of Abraham, perhaps that of Peleg. 1510, 2015, perhaps 2556 BC, or 1447, 942 down to 401 years after the Flood.

8848 m : 1447 years = 6.115 meters per year
8848 m : 942 years = 9.393 meters per year
8848 m : 401 years = 22.065 meters per year.

6 115 mm : 365.2425 days = 16.742 mm / day = 1.395 mm / hour
9 393 mm : 365.2425 days = 25.717 mm / day = 2.143 mm / hour
22 065 mm : 365.2425 days = 60.412 mm / day = 5.034 mm / hour

Still a very strong uplift, considering all the cubic meters needed for each mm higher of Mount Everest ... probably too shaky to live on, but we do not have evidence of human post-Flood settlement in Himalayas before the ... wait, we do have the Patu industry in Nepal* carbon dated to c. 7000 BP, meaning before Genesis 14 in 1935 BC, perhaps even before the birth of Abraham.** I am supposing the Soanian culture was pre-Flood, dated by K-Ar and therefore getting high ages from rapid lava cooling during the Flood.

This means, the quakes, if any, may have been irrelevant to where mankind were mainly living.

This means, Himalayas rising after the Flood remains possible, contrary to one of the lines of reasoning leading to Catholics in late 19th C abandoning in certain countries and social strata*** the Biblical timescale.

** According to this table extract it would be somewhere between or around deaths of Peleg and Eber:

2249 BC

67.347 pmc, 5499 BC

Peleg +

2217 BC

Eber +

2186 BC

2170 BC

72.031 pmc, 4870 BC

Last entry doesn't read as anything being actually 4870 BC, but "in 2170 BC [according to this model] carbon level had risen to 72.031 pmc making for 2700 extra years of instant age, meaning the carbon date, which adds the extra years to the real years while initial pmc is compounded by - in this case 56.498 % of - the actual decay, meaning we now have 40.696 pmc leading to it's carbon date as 7450 years ago or 5430 ... 4870 BC". The recalculations didn't quite match up, but near enough? I used this to do them:

The original calculations for the table did not try to involve directly the modern pmc in the objects from back then, only to add extra years to real years .... 2170 BC augmented by 2700 extra years. It's from here:

*** If all Catholics had abandoned it, even 1 day, either Old Age would be acceptably as true, or question irrelevant, or Christ would have lied or promised too much in Mt 28:20. If only some did, this leaves Young Earth a per se obliging position, and Catholicism the true Church.
