Dating the rocks of the grand canyon
Also in Part Two, we are introduced to relative and absolute dating methods.
Relative dating methods include fossil assemblages (groupings of various fossils commonly associated with each other) found in various localities not physically connected.
Having tried to extract microscopic seeds from sedimentary rock, I know a little of the tedious methods that are applied.
Strong chemicals, such as hydrofluoric acid (HF), are used.
Radiometric dating techniques provide the absolute dates.Opening with a Foreword that discusses the recent history of the Grand Canyon, the reader is drawn into a journey of time, beginning with the first humans to witness its grandeur, "Humans have interacted with this deep gorge since prehistoric times," to modern geologists deciphering its history.In an introduction to the coming discussions on the age of the Earth, the authors explain that it "was not until the beginning of the twentieth century that religious opposition began to be voiced against the antiquity of the Earth." Part One discusses "Two Views" concerning the origin of the Grand Canyon - the YEC view and the modern, or conventional, geologic view.The illustrations are professional and would fit well into any modern geology textbook.Part Two would serve well as a primer for any college geology course.Here again, the authors expertise in geology stand out.The modern geologic model for the formation of the Grand Canyon is laid out.In 1995, the Institute for Creation Research (ICR) published a book by Stephen A. Specifically, they, along with a host of other scientists (mostly geologists), wanted to address the way Dr.Austin presented the geologic record of the Grand Canyon, which was misleading.This book, , by Carol Hill et al., is a journey through rock and time, from the bottom of the Grand Canyon to the top of the Grand Staircase.Meant for the Christian non-scientist, you'll find answers to questions, such as "How old are the rocks in the Canyon? " They also discuss whether Noah's Flood carved the Grand Canyon.
