About this book

Framboids may be the most astonishing and abundant natural features you've never heard of. These microscopic spherules of golden pyrite consist of thousands of even smaller microcrystals often arranged in stunning geometric arrays. They are rarely more than twenty micrometres across and often look like minuscule raspberries under the microscope.

The formation of a framboid is the result of the self-assembly of pyrite micro- and nano-crystals under the influence of surface forces. They can be found all around us in rocks of all ages and present-day sediments, soils, and natural waters. Our planet makes billions every second and has been doing so for most of recorded geologic time. As a result, there are more framboids on our planet than there are sand grains on Earth or stars in the observable universe.

The microscopic size of framboids belies their importance to contemporary science. They help us better understand inorganic self-assembly and self-organization, and studying them illuminates Earth's evolutionary history.

In Framboids, David Rickard explains what framboids are, how they are formed, and what we can learn from them. The book's thirteen chapters trace everything from their basic attributes and mineralogy to their biogeochemistry and paleoenvironmental significance. Rickard expands on the most updated research and recent developments in geology, chemistry, biology, materials science, biogeochemistry, mineralogy, and crystallography, making this a must-have guide for researchers.

Media reviews

"Framboidal pyrite; a riddle wrapped in a mystery inside an enigma. An engaging text on mineral morphology seems a contradiction in terms, but Rickard's superbly crafted book will surprise and inform readers at all levels. Popular audiences will be awestruck by the sheer profligacy of framboid formation: more than ten thousand billion framboids are formed every second, giving a worldwide abundance a billion times larger than the number of sand grains on Earth. Professionals will get a closer look into the physio-chemical controls of burst nucleation that produce the exquisite architecture of framboidal pyrite"
– Rob Raiswell, School of Earth and Environment, University of Leeds

"There is a mystery behind framboids. They represent fool's gold, many compare their appearance to that of a tasty raspberry, and they're invisible to the naked eye. In this book, Dave Rickard expertly provides readers with the most recent data about framboids, and he also delves into the history and future of framboids. This is a must-have for Earth scientists, chemists, and materials scientists."
– Zbigniew Sawlowicz, Institute of Geological Sciences, Jagiellonian University

"I found Framboids to be a fun and highly educational read. Ever since I first saw a pyrite framboid, I wondered how these entities could arrange themselves in such beautiful symmetries. In this book, David Rickard documents how other compounds generate framboids and that these materials are everywhere even though they cannot easily be seen. Rickard does a spectacular job in providing the history of their discovery, starting with optical microscopy through more advanced electron microscopy methods. For the scientist who wishes to understand the physical and chemical forces that align microcrystals into framboids, he provides an exquisite step-by-step dissertation regarding their formation, growth mechanisms, nucleation, self-assembly, and self-organization."
– George W. Luther, III, School of Marine Science and Policy, University of Delaware and author of Inorganic Chemistry for Geochemistry and Environmental Sciences
