James Hutton's Reputation Among Geologists in the Late Eighteenth and Nineteenth Centuries
The Geological Society of America Memoir 216 Revising the Revisions: James Hutton’s Reputation among Geologists in the Late Eighteenth and Nineteenth Centuries A. M. Celâl Şengör* İTÜ Avrasya Yerbilimleri Enstitüsü ve Maden Fakültesi, Jeoloji Bölümü, Ayazağa 34469 İstanbul, Turkey ABSTRACT A recent fad in the historiography of geology is to consider the Scottish polymath James Hutton’s Theory of the Earth the last of the “theories of the earth” genre of publications that had begun developing in the seventeenth century and to regard it as something behind the times already in the late eighteenth century and which was subsequently remembered only because some later geologists, particularly Hutton’s countryman Sir Archibald Geikie, found it convenient to represent it as a precursor of the prevailing opinions of the day. By contrast, the available documentation, pub- lished and unpublished, shows that Hutton’s theory was considered as something completely new by his contemporaries, very different from anything that preceded it, whether they agreed with him or not, and that it was widely discussed both in his own country and abroad—from St. Petersburg through Europe to New York. By the end of the third decade in the nineteenth century, many very respectable geologists began seeing in him “the father of modern geology” even before Sir Archibald was born (in 1835). Before long, even popular books on geology and general encyclopedias began spreading the same conviction. A review of the geological literature of the late eighteenth and the nineteenth centuries shows that Hutton was not only remembered, but his ideas were in fact considered part of the current science and discussed accord- ingly. -

Effects of Atmospheric Breakup on Crater Field Formation 1
ICARUS 42, 211--233 (1980) Effects of Atmospheric Breakup on Crater Field Formation 1 QUINN R. PASSEY AND H. J. MELOSH z Division of Geological and Planetary Sciences, California Institute of Technology, Pasadena, California 91125 Received October 5, 1979; revised February 18, 1980 This paper investigates the physics of meteoroid breakup in the atmosphere and its implications for the observed features of strewn fields. There are several effects which cause dispersion of the meteoroid fragments: gravity, differential lift of the fragments, bow shock interaction just after breakup, centripetal separation by a rotating meteroid, and possibly a dynamical transverse separation resulting from the crushing deceleration in the atmosphere. Of these, we show that gravity alone can produce the common pattern in which the largest crater occurs at the downrange end of the scatter ellipse. The average lift-to-drag ratio of the tumbling fragments must be less than about 10 -3, otherwise small fragments would produce small craters downrange of the main crater, and this is not generally observed. The cross-range dispersion is probably due to the combined effects of bow shock interaction, crushing deceleration, and possibly spinning of the meteoroid. A number of terrestrial strewn fields are discussed in the light of these ideas, which are formulated quantitatively for a range of meteoroid velocities, entry angles, and crushing strengths. It is found that when the crater size exceeds about 1 km, the separation between the fragments upon landing is a fraction of their own diameter, so that the crater formed by such a fragmented meteoroid is almost indistinguishable from that formed by a solid body of the same total mass and velocity. -
Volcaniclastic Aeolian Dunes: Terrestrial Examples and Application to Martian Sands
Volcaniclastic aeolian dunes: Terrestrial examples and application to martian sands K. S. Edgett1 and N. Lancaster2 1 Department of Geology, Arizona State University, Tempe, Arizona 85287–1404, U.S.A. 2 Quaternary Science Center, Desert Research Institute, P.O. Box 60220, Reno, Nevada 89506, U.S.A. Abstract. On Earth, most aeolian dunes are quartz rich; others are composed of evaporites, carbonates, or clay/silt aggregates. Dunes made of wind-reworked volcaniclastic sediment comprise a less-commonly recognized fifth dune composition. Terrestrial volcaniclastic aeolian dunes are found in (1) arid to semi-arid volcanic regions and (2) coastal areas on volcanic islands. Their sediments can be formed by explosive volcanism or by erosion of lava flows and other lithified volcanic material. Commonly, these sediments have been transported by volcanic and/or fluvial processes before being reworked by wind. Their compositions range from mafic to sialic, depending on local volcanic sources. Volcaniclastic dunes, especially those of basaltic composition, may be the best compositional analog for aeolian dunes on Mars. Martian dunes are typically dark- hued and their sands may be derived from erosion of volcanic materials. received 9 June 1992, accepted 21 July 1992, published September 1993 Citation: Edgett, K.

[1] The volcanic plains that fill the Caloris basin, the largest recognized impact basin on Mercury, are deformed by many graben and wrinkle ridges, among which the multitude of radial graben of Pantheon Fossae allow us to resolve variations in the depth extent of associated faulting. Displacement profiles and displacement-to-length scaling both indicate that faults near the basin center are confined to a ~ 4-km-thick mechanical layer, whereas faults far from the center penetrate more deeply. The fault scaling also indicates that the graben formed in mechanically strong material, which we identify with dry basalt-like plains. These plains were also affected by changes in long-wavelength topography, including undulations with wavelengths of up to 1300 km and amplitudes of 2.5 to 3 km. Geographic correlation of the depth extent of faulting with topographic variations allows a first-order interpretation of the subsurface structure and mechanical stratigraphy in the basin. Further, crosscutting and superposition relationships among plains, faults, craters, and topography indicate that development of long-wavelength topographic variations followed plains emplacement, faulting, and much of the cratering within the Caloris basin. -
