How can the very top, volcanic rock be older than the very bottom layer basalt rock?
Then they ALWAYS come back dated at 100,000s to millions of years old. NEVER do they come back from the lab, with the note: Too young to measure. If you know the date of the source of the rock, they say you don’t have to accept this dating technique’s numbers… But recently, the RATE research team has conclusively demonstrated (with independent lines of evidence) that radioactive decay rates, widely used to bolster deep time, were dramatically accelerated in the past.
but if its an unknown sample, then they say: “Oh, you can trust the lab dates! You see, the radiometric dating technique’s do not work when you can check the dates, but you should trust them when you can’t check them. RATE found 3 indicators that strongly indicate decay rates changed in the past, all pointing to a young age for the rocks and the earth.
To assume the rock starts with only U and no Pb is a big assumption.
(Isochron dating, which relies on multiple rock samples, is an attempt to correct this, but still has underlying assumptions based on 1 and 2 above.) Examples of Problems with Radiometric dating of rocks: Grand Canyon Lava flows: Sedimentary rocks make up the layers of the Grand Canyon and these are not dateable by radiometric dating.
How do we know that there wasn’t lead in the rock when it was first formed?
What is the real initial percentages of the U parent and Pb (lead) daughter elements?All the canyon layers are ocean bottom sediments, filled with fossils of ocean-dwelling creatures and plants almost a mile high from top to bottom.The Cardenas Basalt bottom layer (below the Cambrian explosion) is usually dated with Rhobidium -Strontium and calculated to be about 1 billion years old.Since the early 20th century, Radioisotope dating has been used to bolster the vast time spans ascribed to the geologic record.However, research by geologist John Woodmorappe (a pen name) revealed that the radiometric methods used today were actually hand-picked to coincide with the dates previously assumed for the geologic column diagrams.Also remember that modern disasters (on a smaller scale) like Mount St.
