Available in PDF, EPUB and Kindle. Book excerpt: In its long and rocky past, the place we call Ontario has traveled across the equator, been peppered and pockmarked by meteorites, seen the rise and decline of towering mountains, and gave rise to some very strange and now extinct organisms. In fact, what seems like a changeless landscape was once covered by vast seas and huge, continent-wide ice sheets which measured 2 kilometres thick, leaving in their wake, the Great Lakes. Ontario Rocks tells this fascinating 3 billion year long story of Ontario's geological evolution, from its beginnings as part of an early landmass called Arctica, its incorporation into enormous supercontinents, through to the repeated ice ages and abrupt climatic changes of the last few thousand years. Merging Canadian geology with global evolution, this highly illustrated survey also touches on the development of Ontario's mining and oil industries, and the commercial use of rocks as building material. Ontario Rocks concludes with an exploration of the "artificial" urban landscape, and how geologists use their knowledge to safeguard groundwater and rivers, dispose of wastes and understand the hazards posed by earthquakes and erosion. Ontario Rocks is a highly accessible sourcebook, perfect for students and all those intrigued by the history and formation of the land under us.

Book excerpt: The Early Proterozoic Michigamme Formation of northern Michigan was deposited in the southeastern part of the Animikie basin. The formation conformably overlies the Goodrich Quartzite and comprises three widespread members a lower member of thin-bedded shale, siltstone, and sandstone; the Bijiki Iron-formation Member; and an upper member of tur- biditic graywacke, siltstone, and mudstone and a few local members. The Goodrich Quartzite is interpreted as having been deposited in a tidally influenced shallow marine environ- ment. The lower member of the Michigamme is interpreted as having been deposited in a tidally influenced environment, the iron-formation member as having been deposited below wave base in somewhat deeper water, and the upper member as having been deposited in still deeper water with turbidity currents being a major depositional mechanism. Several lines of evidence including paleocurrents, paleo- geographic setting, and neodymium isotopes suggest that the graywacke of the southern part of the outcrop area was derived from the south (Early Proterozoic Wisconsin magmatic terranes, Archean miniplates, and older Early Proterozoic sedimentary units formed on the continental margin), and that the graywacke in the northern area was derived from an Archean terrane to the north. The tectonic model that best fits the available data is a northward-migrating foreland basin.
