The Rejection of Continental Drift: Theory and Method in American Earth Science Reviews

Product Overview

In the early twentieth century, American earth scientists were united in their opposition to the new--and highly radical--notion of continental drift, even going so far as to label the theory "unscientific." Some fifty years later, however, continental drift was heralded as a major scientific breakthrough and today it is accepted as scientific fact. Why did American geologists reject so adamantly an idea that is now considered a cornerstone of the discipline? And why were their European colleagues receptive to it so much earlier? This book, based on extensive archival research on three continents, provides important new answers while giving the first detailed account of the American geological community in the first half of the century. Challenging previous historical work on this episode, Naomi Oreskes shows that continental drift was not rejected for the lack of a causal mechanism, but because it seemed to conflict with the basic standards of practice in American geology. This account provides a compelling look at how scientific ideas are made and unmade.

Precambrian continental freeboard and geological evolution: A time perspective [An article from: Earth Science Reviews] | | Reviews

Product Overview

This digital document is a journal article from Earth Science Reviews, published by Elsevier in 2006. The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser.

Description:
Continental crustal growth rates, crustal volumes/thicknesses, and continental freeboard are considered to be intimately related; however none are easy to quantify, least of all in the Precambrian. Additionally, crustal volumes/thicknesses and isostasy are related to changing mantle heat and the concomitant variation in thickness of ocean crust. Another set of variables would be the interaction of plate tectonics (and the onset of plate tectonics, a contentious issue in itself) and mantle plumes/superplumes. Further complication is provided by the ranges of freeboard elevations and eustatic sea level changes overlapping in scale, and sharing common genetic causes. The ''constant freeboard model'' suggests that the net results of the interaction of this complex set of variables has been that continental elevation relative to sea level, has remained essentially similar, on a global average basis, over much of geological time, assuming an essentially constant ocean volume since c. 3.8 Ga. Application of this model to the Precambrian geological record suggests that sigmoidal crustal growth rate models are probably the most reliable. A conundrum of the constant freeboard model would be that freeboard would tend to become lowered towards mean sea level for any specific craton over time; this ''freeboard-equilibrium'' would be interrupted for a particular craton by active geodynamic processes resulting from the interplay of plate tectonics and mantle thermal instabilities. In this paper we test the validity of this thesis of alternating approximate freeboard-equilibrium and active geodynamics, by examining the volcano-sedimentary record of a number of cratons: Kaapvaal, Singhbhum and Pilbara. For the Singhbhum craton (and bearing in mind its poor chronological data base), freeboard-equilibrium appears to have prevailed until c. 2.1 Ga, but for Kaapvaal and Pilbara, until c. 1.8 Ga, the geodynamic processes largely outweighed the tendency towards equilibrium, except for c. 200 My from c. 2.6 to 2.4 Ga when global sea level appears to have remained high and transgression was the norm. We thus tentatively add the plate tectonic cycle and mantle-thermal processes to the already complex association of concepts controlling continental freeboard over time.
