Moldavite is the same thing as a Tektite, which has a green cast like coke bottle glass. The better quality grade has a distinct fern-like pattern. Most the Moldavite is mined out of the Czech Republic. It is thought to be related to a 15 million year old meteor, but not related to the extinction of the dinosaurs. The meteor responsible for the dinosaurs, hit with such impact, that only granules or dust can be found.
The convergence of time lines between scripture and geological data is nearly impossible verify. I do feel there are some serious gaps in our canon of scripture when it comes to time tables, but I will not say the scriptures are in error. I would say they essentially do not provide much detail in certain areas, leaving MUCH to speculate. The scriptures were gathered more as guide for human kind, not as historical documentation.
I do firmly believe that a asteroid slammed into the earth ending the reign of the dinosaurs. The standard theory states that a giant asteroid about 6 miles wide smashed into the Yucatan Peninsula close to the current Mexican town of Chicxulub about 65 million years ago (time frame exaggerated). The impact raised enough dust and debris to blot out the sun for decades or even centuries. Such a large impact would also have triggered a host of natural disasters, including volcanic eruptions, earthquakes, tsunamis and global firestorms that cooked, starved and suffocated the mammals. Computer modeling studies have shown that within hours of the impact the entire atmosphere would have caught fire due to the ejecta returning to earth - over and over again as the planet rotated, setting off a repeating global firestorm lasting weeks and reaching into the hundred, even thousands of degrees Fahrenheit. Basically, anything that couldn't hide in a burrow was cooked before being burned to a cinder. Animals like the crocodile is a known descendent surviving this event including some birds.
Iridium is a chemical element commonly found in asteroids and comets and the K-T boundary has been touted as the smoking gun linking the dinosaurs' demise to an asteroid impact. Markus Harting of the University of Utrecht in the Netherlands and a small group of scientists thinks the Chicxulub impact happened too early to have been the infamous dinosaur-killer. Harting believes his work supports the theory that the Chicxulub impact occurred roughly 300,000 years earlier than many scientists have commonly assumed which only proves that no one really knows.
Due to the large margins of error involved, Harting could not determine the age of the spherules found in multiple layers of sediments from northeast Mexico, Texas, Guatemala, Belize and Haitibut. Instead relied on studies of sediment deposits performed by Gerta Keller at Princeton University and colleagues.
Keller cites a thick layer of sediment found between the Chicxulub impact layer and the K-T boundary as evidence that the Chicxulub asteroid impact occurred well before the extinction of the dinosaurs. Keller also claims to have found evidence of Cretaceous-era fossils in sediments above layers of rock linked to the asteroid impact.
Keller thinks dinosaurs survived the Chicxulub impact but were finished off by a larger, more catastrophic impact that happened roughly 300,000 years later. It was this later impact, Keller says, that is responsible for the K-T boundary. She believes the asteroid that did kill the dinosaurs probably struck Earth somewhere else and remains undiscovered.
Recent work by other scientists, for example, has shown that fossil records could have been shuffled around by an enormous tsunami that would have followed such a significant asteroid impact. This would explain Keller's anomalous fossils, they argue.
Denton Ebel, assistant curator of meteorites at the American Museum of Natural History, compares Harting's spherule analysis to trying to understand the eruption history of Mount St. Helens by examining a sediment core drilled out of the top of the volcano. Because the Chicxulub impact would have been many orders of magnitude stronger than any volcano eruption, scientists have to travel hundreds or even thousands of miles from ground zero to find sediment layers not disturbed by the impact.
Frank Kyte of the University of California, Los Angeles has done just that. Kyte has analyzed the chemical composition of spherules collected from the K-T boundary layer in places all around the world, including deep ocean basins, where the sediment isn't as churned up as in the Gulf of Mexico. From his studies, Kyte has concluded that there is only one spherule layer, not many as Harting claims, and that this layer is located precisely at the K-T boundary.
Kyte dismisses the idea that an asteroid impact different from the one that occurred at Chicxulub was responsible for the dinosaur's mass extinction. "There is all kinds of evidence that there was one big impact, and virtually no solid, strong evidence that there was more than one," he said.
So for lack of better information in 2008, the last I knew, the Chicxulub impact is highly favored as the big one. Nothing is left of this event to make jewerly from
