To many of us, the Earth’s crust is a relic of ancient, unknowable history. But to a geologist, stones are richly illustrated narratives, telling gothic tales of cataclysm and reincarnation. For more than four billion years, in beach sand, granite, and garnet schists, the planet has kept a rich and idiosyncratic journal of its past. Fulbright Scholar Marcia Bjornerud takes the reader along on an eye-opening tour of Deep Time, explaining in elegant prose what we see and feel beneath our feet. Both scientist and storyteller, Bjornerud uses anecdotes and metaphors to remind us that our home is a living thing with lessons to teach. Containing a glossary and detailed timescale, as well as vivid descriptions and historic accounts,
Reading the Rocks
is literally a history of the world, for all friends of the Earth.

A good intro to earth sciences. Despite the title, this book is only partly about rocks. The reason I got it was to get an introduction to geology, and it gave me a little of that, but not as much as I was looking for.
But it does an admirable job of overview not only geology, but also covers the evolution of life, the origins of the solar system, and other far-flung subjects--all in 200 pages.

The sections on subjects I already knew well were still interesting, but I'm not sure how well the geology I learned in the book will stick, since those parts sometimes read more like a laundry list of facts than like a flowing narrative.

This gal can really write. Among books in the genre "Science Not For Dummies." it's a standout. I had no background in geological earth science to speak of so I found the material rather dense (sorry, we're talking rocks here) but Prof. Bjornerud explains her terms and uses parallels from common experience to help the reader relate.

There's a glossary worth using. I've started reading this again. It's worth it, and I expect by the second time through I'll have learned enough to take on other works about this subject that's so often pushed aside in our scientific schooling. After returning a copy to the library, I've bought two, one for myself and one as a gift. Budget well spent.

When the author focuses on geology, I liked it very much. Good attempt to find homely metaphors for geological processes. When she start on how we're running everything into the ground, I got bored
My dear most brilliant man,
I can see why you are using this book with your students. It reminds me very much of your own teaching style. I love her use of analogy to common, well-known, everyday situations, events and things to explain these concepts of science. That is so you. I particularly liked the analogy she used when explaining radioactivity. That was helpful. And I loved how detailed she got in explaining the problems and difficulties of the process. It was all most interesting.

My dear most brilliant man,
I can see why you are using this book with your students. It reminds me very much of your own teaching style.

I particularly liked the analogy she used when explaining radioactivity. That was helpful. And I loved how detailed she got in explaining the problems and difficulties of the process. It was all most interesting.
Once I hit chapter 4 where she begins to focus more on the ideas where biology ties into geology, the analogies abruptly stopped and everything became very technical. At that point I had a hard time remaining focused. It was all so confusing, and I didn’t feel like I was learning the things I needed and wanted to know about it all. It seemed she was assuming her readers had a knowledge that I didn’t feel I had.
Overall I think this is a good book. The assumptions weren’t as clearly stated as I would have liked, but they were fairly easy to pick out. While she seemed to rely pretty heavily on her assumptions in the middle, the beginning chapters were quite good. And I really liked some of her conclusions toward the end.
Thanks again for helping me expand my horizons.
Your Constance

Reading the Rocks is a perfect book for me, since its two themes, geology and humanity's atrocities against the planet, are both things that fascinate me more than most things. And as a pop geology book, Bjornerud makes a contribution worth reading alongside books that are perhaps better written or give more information, like Richard Fortey's Earth, or Bill Bryson's A Short History of Nearly Everything. She does give information that is still new and fascinating after reading those two books.

She does give information that is still new and fascinating after reading those two books.
However, the latter issue, which seems to be the major theme of the book and her personal preoccupation, is given very little treatment in the book. It is simply stated that we should change our attitude towards the Earth, that we should be less presumptuous and more respectful, and that we should consider our actions more before we take them. She offers no analysis of what humans have done so far, nor does she give any suggestions for the reader about what they can do. She treats the whole of humanity as one individual, with particular attitudes towards the environment and an overarching consciousness and cohesive decision-making process, and then acts as though this unified human consciousness is her audience. This all ignores the fact that human actions collectively are determined as a result of natural social selection and emergence, not of conscious group decisions. And thus the problems we face will not be solved by mere attitude change. The social forces that are destroying our planet operate at a much deeper level than our personal ideologies and attitudes.
P.S. - This afternoon I went to a Q&A session with the author, who made it clear that the things I found fault with above. She apparently wanted to avoid being preachy or proselytizing, and instead merely present the evidence and her sentiment and let the reader judge for itself.
It is overall worth reading for its science value, but it is not particularly deep.

I liked
Reading the Rocks
. It has lots of little (often amusing) comments in parentheses, which is a lot like the way I think (and it comes out in my writing). I liked reading about geology and prehistory, and it was interesting to see all of the writing techniques I've been learning in Language Arts and English finally pop up in my reading. I would recommend this book to anyone who is curios about geology.
The title, Reading the Rocks, made me think this would have more to do with actual rocks than it did. There was some bits about rocks but more of it was on a much bigger scale. Thus the sub-title. Definitely a book chock full of information without getting overly technical. It was very consistent throughout making it relatively easy to follow. I say relatively, because it will definitely make you pause and think. At least it did for me, because the information was so far beyond what I previously

I say relatively, because it will definitely make you pause and think. At least it did for me, because the information was so far beyond what I previously understood. And I've read books on geology before. Still, the ending was a bit of a let down for me, since it didn't really add anything compared to the contents of the meatier chapters. And the title reads a little better for me as first an autobiography of the earth. But overall, she explains quite well how they came to know these things by reading the rocks. Highly recommended!

This was a very accessible and enjoyable read about the major geologic events shaping Earth's history. I definitely learned some new things (a time before plate tectonics???) and was thoroughly engrossed in discovering exactly how delicate the balance truly has to be in order for our planet to sustain life.
This book is a good overview/intro about how geologists use rocks to make educated guesses about the earth's climatological and biological history - a very difficult topic to explain to an average citizen with a vague recollection of high school science class. Because the subject is so huge (history of the planet Earth) and the science so technical (chemistry of how rocks change over time), it felt at times that the author had to simplify many concepts and that I was not fully understanding what

However the author does come up with some clever metaphors and the concepts were certainly interesting enough to hold my attention.

This is one of the most important books I have read. It has given me a deep appreciation for the thin biosphere that is covering our orbiting rock planet. The depth of awareness offered by Marcia Bjornerud, if truly perceived, is the essence of enlightenment. What more is there to be said, except, read this book.
Bjornerud loves her metaphors and analogies! This book all in all, was a great piece of work. Since I'm a geology major, some of the ideas presented (mainly in the first few chapters) were all review, but she talked about rock types in a clear, interesting manor - enough so that I believe anyone with a small background of rocks would really learn from and enjoy this book. My only frustration with it is that it's more of an intro to geology, which I wasn't really looking for.
This book was really about a 3.5. Generally a good semi-basic book about Earth's biogeochemical history. The author did a good job explaining concepts in biology, geology and in environmental science in clear and concise ways. Generally, her explanations were entertaining and enjoyable. There were some times, however, when (even knowing a fair amount of geology) I had to reread to ensure I was understanding where she was going with her explanation.
I'm only 1/3 of the way into this today but I'm delighted. Bjornerud explains what seems like capricious indecisiveness of geological terms for naming/describing rocks. Every definintion comes with her clear cautionary commentary. She's a born teacher. I'm finding after my 5 years of geology lectures and field trips,she's finally pulling it together for me. This book is my platinum-find.
I liked the first part of the book a great deal but the last 30 pages or so, I could have done without. I don't feel like the added content to the book at all. While the prose was interesting and the topics with interesting for the first part, the last didn't interest me and I felt like it was even written differently.
I learned a lot about geology from this book. It was a surprisingly easy read, but there were way too many metaphors, and some were really awkward. She should have stuck to geology though. When she touched on biology her lack of understanding was a bit embarassing and I didn't appreciate the preachy tone.
An excellent introduction to geology that made me think I would have enjoyed majoring in it in college. The author knows her stuff and knows beginners, challenging us to learn terms and processes early on so that we can understand the more complex ideas later on. Well worth reading.
Brilliant and lyrical account of how the earth functions (machine, organism, neither/both) through the lens of geology and mysteries it unlocks. This is the second time I've read this and will read it again at some point.
“With each integer on the Richter scale, there is a tenfold increase in the number of earthquakes that occur annually. On average, there is one magnitude 8 event, ten magnitude 7 events, a hundred magnitude 6 events, and so on, each year. If we consider this from an energy standpoint, the smaller earthquakes account for a significant fraction of the total seismic energy released each year. The one million magnitude 2 events (which are too small to be felt except instrumentally) collectively release as much energy as does one magnitude 6 earthquake. Although the larger events are certainly more devastating from a human perspective, they are geologically no more important than the myriad less newsworthy small ones.”

“If we extrapolate this rate of overturn back in geologic time, the ocean floor has apparently been rejuvenated at least two dozen times since the Earth formed. When Earth was younger and hotter, however, the pace of convection may have been faster, and the ocean floor may have been resurfaced more frequently. But this leads to a conundrum: If convection had been faster in the past, as most geoscientists think it was, ocean crust would have arrived at subduction zones at a younger average age, still too hot and buoyant to be assimilated back into the mantle. This suggests that true plate tectonics, with rigid crustal slabs, efficient recycling of ocean crust via subduction, and water-assisted production of low-temperature melts, may not have occurred on the early Earth. Instead, plate tectonics could begin only when the Earth had reached a degree of thermal maturity, probably about 2.5 billion years ago (around the close of the Archean eon and the beginning of the Proterozoic). Before this, Earth's mixer settings—and the extent to which surface water was stirred back into the interior—were probably different. We can look to rocks formed in these distant times, Earth's record of its childhood and youth, for clues.”
