_Thanks a lot for the quotes you gave me about crustal shortening etc.
_I asked Robert to discuss our disagreements on catastrophism, because I think it would settle our differences.
_I also started a paper on Impact-Flood Catastrophism on the CNPS forum at http://forums.naturalphilosophy.org/forumdisplay.php?fid=127
_Here's what I wrote. Do you suggest any corrections or additions to the list?
_IMPACT-FLOOD CATASTROPHISM: ESSENTIAL ELEMENTS & DEFINITIONS
_Planetoid: any rocky body in outer space: i.e. meteor, comet, asteroid, moon, rocky planet
_Recent Planetoidal Near-Collision/s: planetoid/s coming close enough to Earth to raise high tides
_Megatides/Megatsunamis: tides/tsunamis high enough to deposit sedimentary rock strata
_Impacts: fall of planetoids on Earth's surface
_Megasequence: conforming strata between unconforming strata
_Megasequences Deposition: deposition of conforming strata
_Supercontinent: large continent composed of smaller continents
_Supercontinent Breakup: breakup of a supercontinent into smaller continents due to impact/s
_Impact Orogeny: mountain uplift caused by continent breakup
_Impact Volcanism: volcanic eruptions caused by impacts
_Radiometric Dating: using radioactive decay in rock to estimate the time it formed
_Radiometric Dating Errors: errors in estimating ages of rock due to changing decay rates
_Gradualism: the theory that large-scale geological features change very gradually, not rapidly
_Gradualism Errors: overlooking the fact that large-scale cataclysms can cause rapid geological changes
_Fossilization: formation of fossils during strata deposition
_Atmosphere Shrinkage: shrinkage of the atmosphere due to rapid losses to space
_Gigantism: tendency of plants and animals to grow to giant size
_End of Gigantism: loss of conditions favoring gigantism
_Ice Age: time of widespread glaciation
_Ancient Myths: ancient anthropomorphic reports about celestial conditions before, during and after cataclysms
_Advanced Ancient Civilization: high tech civilization in ancient times, destroyed by cataclysms

_You are taking real initiative in this project.  As requested, my wording of your list is below.
_IMPACT GENERATED FLOOD CATASTROPHISM - ESSENTIAL ELEMENTS & DEFINITIONS
_Planetoid: any rocky body in outer space: i.e. meteor, comet, asteroid, moon, rocky planet
_Planetoid Near-Collision/s: the possibility that one or more planetoids came close enough to Earth to raise high tides
_Megatides/Megatsunamis: tides/tsunamis large enough to deposit sedimentary rock strata
_Impacts: fall of planetoids onto Earth's surface
_Megasequence: conforming strata between unconformities
_Megasequence Deposition: deposition of conforming strata
_Supercontinent: large continent composed of smaller landmasses
_Supercontinent Breakup: breakup of a supercontinent into separate continents
_Impact Orogeny: mountain uplift caused by rapid continent breakup following a giant planetoid impact
_Impact Volcanism: volcanic eruption caused directly or indirectly by planetoid impact
_Radiometric Dating: using radioactive decay and its products to determine age
_Radiometric Dating Errors: errors due to invalid assumptions in radiometric dating
_Gradualism: the theory that large-scale geological features change very gradually, not rapidly; the present is the key to the past
_Gradualism Errors: overlooking the influence of cataclysms on geology
_Fossilization: burial of organisms and/or evidence of their activity during strata deposition
_Atmosphere Shrinkage: dissipation of the atmosphere due to rapid loss of gas into outer space
_Gigantism: tendency of plants and animals to grow to giant size
_End of Gigantism: loss of conditions favoring gigantism
_Ice Age: period of extensive glaciation
_Ancient Celestial Catastrophic Myths: ancient human stories about celestial conditions before, during and after cataclysms
_Advanced Ancient Civilization: proposed high tech civilization in ancient times, allegedly destroyed by cataclysm

_Hi Mike. Robert Farrar was discussing granite a couple weeks ago. I lived in New Hampshire a few years ago and noticed that their granite seems to be metamorphosed sedimentary rock. Do you know why sometimes the sedimentary rocks in mountain ranges metamorphosed, while most of the time, I think, they remained sedimentary? Where the strata are folded in mountain ranges, would those be metamorphosed, or not? My impression was that they're sedimentary, but I'm starting to suspect that they must metamorphose. Do you agree or not? Could most or all granites be metamorphosed sedimentary rock?
_Following are passages from a recent post by Robert in a different thread. Could you comment on what you agree and disagree with? He seems to contradict himself a little regarding sedimentary rock.

_... how ... do we explain the dual nature of the Earth’s crust?
_... I have suggested that Earth may well contain a hollow
_such a hollow would serve as a reservoir for hydrogen, methane, ammonia, silane etc.
_Results from the Kola Super-deep borehole show a counter-intuitive exponential increase of rock porosity with depth.
_Such porosity would enable elements from deep within the Earth to migrate to the surface.
_Near the surface upwelling methane is gradually oxidised CH4 + O2 = 2H2O + C, leaving behind vast deposits of oil and coal.
_... Clearly upwelling methane contributes to Earth’s water budget.
_The principal ... volcanic gases ... are H2O, H2,CH4 (and other hydrocarbons), O2, CO, CO2" [etc].
_It would seem that most volcanic eruptions have less to do with the popular picture of molten rock and more to do with upwelling methane reacting with plentiful amounts of oxygen in the Earth’s crust.
_Upwelling silane too, is oxidised as it approaches the surface....

_The origin of the ‘continental crust’
_Basalt is one of the most common rock types found on Earth and ... on all the terrestrial planets.
_... On Earth the largest occurrences of basalt are on the ocean floor which is almost completely made up of basalt.
_On the continents themselves we find outpourings of rock normally associated with the ocean floor - basalt is the rock most typical of large igneous provinces.
_... “Ancient Precambrian basalts are usually only found in fold and thrust belts, and are often heavily metamorphosed.”
_... Upon the Earth’s basaltic foundation we find features not found on the other terrestrial planets, the continents.
_We have previously seen that a product of the silane - oxygen reaction is silica
_is it possible that the continents themselves formed from the outgassing of silicon dioxide?
_We could picture the early Earth as being Venus-like in its topographic appearance with very little relief.
_Over time outpourings of silica collected, perhaps around localised elevated regions of the basaltic ‘primary’ crust or areas undergoing outgassing.
_Water collected initially in depressions in the basaltic ‘primary’ crust.
_... Modern day analogous processes would include deep sea vents, particularly ‘white smokers’ which emit minerals comprising barium, calcium and silicon.
_Such vents are known to develop ‘chimneys’,
_geomorphic and geologic structures on Earth today show a resemblance to ‘chimneys’ formed long-ago;
_they are variously described as ‘Limestone pillars’, ’Sand-columns’, ’Sandstone pillars’, ‘Pipes’, and perhaps we could include ‘Monadnocks’ and ‘Inselbergs’.
_On land we find geysers leave similar silica deposits.
_In North Africa today we find a geological feature known as the ‘Richat Structure’.
_... Its centre consists of a siliceous breccia covering an area that is at least 30 kilometres (19 mi) in diameter.
_“Exposed within the interior of the Richat Structure are a variety of intrusive and extrusive igneous rocks.
_They include rhyolitic volcanic rocks, gabbros, carbonatites and kimberlites. The rhyolitic rocks consist of lava flows and hydrothermally altered tuffaceous rocks that are part of two distinct eruptive centers, which are interpreted to be the eroded remains of two maars.
_... These intrusive igneous rocks are interpreted as indicating the presence of a large alkaline igneous intrusion that currently underlies the Richat Structure and created it by uplifting the overlying rock.

_... Sedimentary Basins and the Precambrian
_... In light of what I have suggested above is it possible that sedimentary basins are not ‘sedimentary’ at all, rather they are ‘outgassing’ or ‘eruptive’ basins?
_... Lowermost ‘sedimentary’ rocks in such basins we can reclassify as ‘pre-sedimentary’ rocks, lacking fossils geologists would assign them to the Precambrian.
_Upper layers would consist of re-worked ‘pre-sedimentary’ rocks, as sedimentary rocks that contain fossils geologists would assign these rock formations to the Phanerozoic.

_... Greenstone Belts
_... “Greenstone belts are primarily formed of volcanic rocks, dominated by basalt, with minor sedimentary rocks inter-leaving the volcanic formations.
_Through time, the degree of sediment contained within greenstone belts has risen, and the amount of ultramafic rock (either as layered intrusions or as volcanic komatiite) has decreased.
_“Sedimentary sequences within greenstone belts comprise both clastic (e.g., conglomerate, quartz arenite, shale and graywacke) and chemically precipitated (e.g., banded iron formation and chert) components.
_... The observed increase in sediment and decrease in basalt type rocks “through time” is explained by what I have proposed here i.e. accumulated silica outgassing.
