Geochronology, Dating, and Precambrian Time: The Beginning of the World as We Know It: summary, description and annotation

We offer to read an annotation, description, summary or preface (depends on what the author of the book "Geochronology, Dating, and Precambrian Time: The Beginning of the World as We Know It" wrote himself). If you haven't found the necessary information about the book — write in the comments, we will try to find it.

Though it encompasses the majority of the Earths history, much about Precambrian time still remains unknown to us. With its climate extremes and unstable surfaces, Precambrian Earth hardly resembled the planet we see today. Yet for all its differences, it made the existence of future generations possible. This volume helps unlock the mysteries of prehistory by considering available geologic evidence while providing a deep dive into the finesses of geochronology.

P lanet Earth was formed roughly 4.6 billion years ago. For human beingsused to measuring time in terms of days, weeks, and monthssuch an enormous span of time can be a difficult concept to grasp. Geologists, scientists who study the Earth and the processes that continue to shape it, have broken up this vast expanse of deep time into major divisions based on what they have learned from the study of ancient rocks and fossils. The first of these divisionsfrom approximately 4.6 billion until 542 million years agois known as the Precambrian, meaning everything that happened before the Cambrian period. (Today some people prefer to call this period the Cryptozoic, which means hidden life.) Almost all of planet Earths history is Precambrian. Until recently, however, it has remained the most unknown, the strangest, and most perplexing period in all geologic historywhat some have referred to as the Dark Ages of Earths existence.

For centuries, the Earth yielded no fossil record to help humans envision Precambrian time. Discoveries of rich caches of fossils from the Cambrian period enabled scientists to assemble a vivid picture of the creatures that inhabited the planet during that time, but the Precambrian Earth remained largely unimaginable. What was known as the missing fossil record of the Precambrian period stood for more than a century as one of the great unsolved mysteries of the natural sciences. This mystery perplexed Charles Darwin and many other scientists who followed in his footsteps. Humans had not yet developed the various methods to accurately determine the age of rocks formed during this interval of geologic time. They had not yet identified and interpreted the remains of the microscopic bacteria that formed in the earliest oceans. The story scientists were beginning to piece together was full of gaps and inconsistencies. It offered glimpses of an alien Earth with an unstable, roiling surface, rocked by volcanic events and cosmic collisions, alternated between extremes of ice and fire, and an atmosphere that would poison most life as we know it today. How did such a hellish place give riseover the course of an almost unimaginable span of yearsto all the familiar features of our planet: oceans, mountains, and valleys, and an oxygen-rich atmosphere that sustains the flowering of plant and animal life in all its countless forms?
