This radioactive decay is like the ticking of a clock, except instead of seconds these radioactive-decay “clocks” are said to measure in millions of years.
By analyzing these parent and daughter elements in a rock and applying today’s measured rates of radioactive decay, geologists confidently claim they can calculate how long it took the radioactive decay of the parents to produce the measured quantities of daughters.
(The number after the ± symbol refers to the error margins in the “age” determination so that 1,103±66 million years means that the age is between 1,037 and 1,169 million years.) So it would seem!
However, a closer examination of the results from all such studies reveals the fallacies of the radioactive dating methods.
The claimed age of 1,103±66 million years was obtained using the rubidium-strontium isochron method with 10 samples and has been regarded as the best radioactive dating result for any Grand Canyon rock unit.
These were once molten lavas that were successively erupted onto the earth’s surface through volcanic vents and fissures and flowed over already deposited layers of siltstones.
They quickly hardened into the dense, black rock called basalt .
Further thick sediment layers were soon deposited on top of them.The position of the Cardenas Basalt lava flows in the overall succession of rock layers in Grand Canyon can be seen in the generalized geologic “block” diagram of Grand Canyon .This article explores the fallacious assumptions used by most secular geologists who apply a uniformitarian belief system (slow-and-gradual geologic processes) when “dating” the rocks of Grand Canyon.Can the exact age of these basalt lavas be determined by their position in the Grand Canyon sequence of rock layers or by physically examining them? However, most geologists classify the Cardenas Basalt as Precambrian; that is, it is older than the so-called Cambrian rock layers such as the Tapeats Sandstone and Bright Angel Shale that contain fossils of marine creatures such as trilobites Figure 2 Grand Canyon map showing the location of outcrops of the Cardenas Basalt lavas.Molten lavas, which successively erupted onto the earth’s surface through volcanic vents and fissures, flowed over already deposited layers of siltstones.They quickly hardened to the dense, black rock called basalt Certain “parent” elements such as potassium, rubidium, uranium and samarium are radioactive and change by decay over time (very slowly according to today’s laboratory measurements) into “daughter” elements argon, strontium, lead and neodymium, respectively.
