Huge chunks of the past have disappeared around the world, a phenomenon known as the “Great Unconformity”. At geological sites where it has occurred, relatively recently formed rocks (according to planetary values) immediately sit much higher, scientists explained last year, blaming “Snowball Earth”, but new evidence contradicts this claim. The Grand Canyon is a geological paradise, creating a kind of layer machine after layer of rock that transforms the past into a lineage. Certain points are characterized by inconsistencies, where there is a sudden leap because no new material was created or some process intermediate stones were snatched from small to high before being deposited.
More than a century ago, geologists noticed that rocks all over North America, about 550 million years old, contained much older material – in some cases up to 3 billion years old. The incident was dubbed as The Great Unconformity and it seems to be worldwide. The period of 550 million years ago is missing everywhere, but it is rarer than expected. Last year, geologists blamed the absence for the time when the planet was almost completely frozen, known as Snowball Earth. Glacier growth and subsequent degradation shattered the rocks below, eventually washing most of it to the sea, they claimed, taking some 60 percent of the Earth’s record to some sort of geological memory.
Dr. of the University of Colorado, Rebecca Flowers has challenged this notion at the National Academy of Sciences Processing. Flowers claims that instead of a single Great Unconformity there was a lot of localized secularism, close enough to confuse geologists, but not all of this could be due to a single global event. The flowers are based on his claim to measurement based on the Colorado Pike Peak, where old rocks were brought to the surface and experienced severe erosion. Flowers dates back to 717 million years ago.
This caused the erosion to create an old imperfection that was the product of Snowball Earth. Instead, Flowers thinks the cause may be a collision between the subcontinent’s Rodiniaand the surrounding tectonic plates, or the subsequent Rodinia separation. Continental collisions create mountain belts, just as India raised the plow Himalayas in Asia, then rapidly eroding.
A similar phenomenon probably happened elsewhere, close enough to create the illusion of being together with our eyes.
Flowers said in a statement, “Researchers have long viewed this as a fundamental boundary of geological history.” “There are many geological records that are missing, but the fact that they are missing means that this history is not easy.”
