Uncertainty in Geology

At ... the American Geophysical Union (see also have published a paper on the Zagros fold and thrust belt that stretches from the Persian Gulf into eastern Turkey (Anatolia), a region of crustal deformation and seismic activity which is interpreted, by necessity, to uniformitarian parameters.

Now we have the leftovers of continental crust in the South Atlantic

It's getting weird from the consensus Plate Tectonics angle,  weirder and weirder. At ... Brazilian geologists have dug a rock out of the ocean bottom, 900 miles east of Rio de Janiero, that appears to be a piece of continental crust that was submerged when the South Atlantic was formed as Africa and South America moved apart. Basically, it is granite and all granites are perceived to be continental rock.


Soemtimes called a rock, sometimes a mineral, flint is usually grey or black (but can also be red or brown when affected by iron oxides, in Aylesbury Vale for example) or even blueish hues. Flint is one of the few rocks or minerals mentioned in the Bible (the Book of Psalms for example, Deuteronomy, Isaiah, etc). In Ireland it is only found in situ in the NE, in the chalk of Co Antrim. However, flint (transported by water and ice) also crops up as far south as Leinster (and as pebbles on the beaches near Dublin).

Crust where it shouldn't be

In Down to Earth issue 83 (May 2013), a geological magazine published by Geosupplies of Chapeltown, Sheffield) there is an interesting take on the Indian Ocean discovery recently published, tagged on the end of the news section. It concerns a piece of continental crust centred around the islands of Reunion and Mauritius and it is suspected it is a strip of crust once attached to Madagascar, the Seychelles, and India. What caught my eye was it then said, the discovery added to the growing debate as to the existence of so-called mantle plumes.

Folding of Mountains

At (March issue) there is also a letter by Peter M James of Tasmania, and he updates some of the information and data pertaining to his article in a previous issue of the journal. Basically, his theory is that the equatorial bulge causes mountain building - and geosyncline activity. This is quite apposite to plate tectonics but this is the primary focus of New Concepts in Global Tectonics. It is a forum for alternative geological scenarios. However, whether they are real or mistaken is for the reader to judge.

Plate Tectonics - why it was adopted

In a letter to the NCGT journal of March 2013, see, Karsten Storetvedt describes his experiences trying to get geology articles published that do not follow the consensus preferred line. Facts and concepts that discredit Plate Tectonics theory, he claims, are either ignored or explained away and papers exposing critical problems with the favoured doctrine are rejected - but the reasons given for not publishing are often non-specific or just patently biased. Sounds familiar.

NCGT Journal March 2013

In the latest issue of the New Concepts in Global Tectonics journal which can be accessed at and the articles are well worth browsing. In the letters section Vidyadhar Raiverman describes the treatment his two books have received from mainstream. These are about Himalayan mountain building processes. They have largely been ignored as his ideas do not fit into the consensus view. One editor in the US openly admitted four specialists refused to review the books as they did not want to upset the Plate Tectonics applecart.

Salt glaciers

In the Zagros mountains of Iran salt domes, a quite common geological oddity, break the surface - see

A forest on the Caribbean sea floor

At ... an underwater forest has been found ten miles off shore of Alabama - and scuba divers have come up with pieces of wood that have apparently been dated, but how sea water might affect those dates is unclear for the moment and what methodology was used. The commenters at the end of the article claimed it was C14 methodology and others claim it was evidence of a Biblical flood event.

Saltier than the Dead Sea

The Weather Eye column in The Times informed its readers of a shallow pond basin, 3300 feet by 1300 feet, in a valley between steep cliffs, on Antarctica (in the McMurdo dry valley system). However, the pond feature is just a few inches deep. The water seems to be sucked out of the atmosphere and it is so salty, some 8 times saltier than the Dead Sea, that it never freezes (Nature, Scientific Reports). The big question that has occurred to space scientists is ... could water behave somewhat like this on Mars?
