{"product_id":"phanerozoic-paleocontinental-world-maps","title":"Phanerozoic Paleocontinental World Maps","description":"\u003cp\u003eFirst published in 1980, this book shows the positions of the major continental areas during the past 560 million years as four series of computer-drawn maps. The maps have been drawn for the present day, 10 and 20 million years ago, then at 20-million-year intervals back to 240 million years, and finally at 40-million-year intervals to 560 million years ago. All the maps are based on quantitative geophysical or topographic information: paleomagnetic pole positions, ocean floor magnetic anomalies, and best fits of the continental margins. Cylindrical equidistant and Lambert equal-area polar projections are used, with a thirty-degree latitude-longitude grid. Many interesting problems in the Earth Sciences are global. These maps provide a framework on which a wide variety of data may be plotted. Problems in fields as widely separated as palenontology, stratigraphy, geochemistry and tectonics may usefully be displayed on these maps.\u003c\/p\u003e","brand":"Cambridge University Press","offers":[{"title":"Default Title","offer_id":46647152738542,"sku":"9780521232586","price":62.82,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/9612\/7726\/files\/9780521232586.jpg?v=1750166239","url":"https:\/\/bookland.com.au\/products\/phanerozoic-paleocontinental-world-maps","provider":"Book Land AU","version":"1.0","type":"link"}
