Radiometric dating of rocks

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 .Thus, radioactive decay of samarium was faster than that of rubidium, which was faster than that of potassium.

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.

It’s even possible the American Indians may have witnessed some of this awesome spectacle.1 Yet, when applying the widely accepted assumptions of secular geologists, these basalt flows yield potassium-argon model ages of around 500,000–1 million years.

Worse still, their rubidium-strontium isochron age is 1,143±220 million years!

Worse still, the samarium-neodymium isochron “age” obtained using 8 samples is 1,588±170 million years—more than three times the potassium-argon isochron “age” of 516±30 million years!

So what is the correct “age” of the Cardenas Basalt lavas?

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.
