another continent (Laurentia) rammed into what is now Scandinavia (the ancient Baltica).

Although such continental collisions (also expected to have occurred in a catastrophic plate tectonics Flood model3) are believed to be capable of metamorphosing crustal rocks, they are considered far too 'docile' for making diamonds. According to Dobrzhinetskaya et al.,4 geothermobarometry, textural studies and fluid-inclusion analyses indicate that the high-pressure phase of metamorphism that produced these Norwegian gneisses involved conditions of 17–21 kbar and approximately 630–820° C. However, this is till not nearly enough to mould carbon into diamond, says Haggerty and conventional wisdom.

Significantly, this Norwegian discovery is not the first, geologists having already reported finding examples of microdiamonds in metamorphic (crustal) rocks twice before, in 1990 in Kazakhstan5 and in 1992 in eastern China.6 While skeptical researchers questioned those earlier reports, this Norwegian discovery makes it harder for the geoscience community to ignore the obvious conclusion that diamonds may also form in crustal rocks.

There are Always Wrinkles

Norwegian micro- diamonds pay no heed to textbooks!! Whereas they should have been in volcanic mantle rocks, they were found in metamorphic rocks.

Originally formed as ancient sedimentary deposits on the Earth's surface, these layers of sediments are believed to have been compacted and cooked (400–450 million years ago!) when

According to Tradition

According to all the geology textbooks, diamonds can only form in the Earth's mantle at depths of more than 120 km (or 75 miles), where the exceedingly high pressures and temperatures — 40 kbar and 900° C — squeeze carbon into the ultracompact crystal structure of diamond. The diamonds then reach the surface when explosive volcanic eruptions force the molten rock containing them up narrow conduits (pipes) through the crust.
