Both show effects of subduction and of the Quaternary collision of Izu Peninsula with Central Honshu. Westward from Suruga Bay, deformation is greatest near the coast, decreases markedly towards the uplifting Akaishi Mountains, and then increases again in the conjugate block-faulted terranes of Chubu district. Quaternary faults, historic earthquakes, and the distribution of horizontal shear straining since ∼1880 all reflect this deformation pattern. Since 1900 the west coast of Suruga Bay has undergone secular subsidence, horizontal contraction and tilting towards Suruga Trough, all typical of the strain buildup process that occurs landward of subduction zones. However, futher westward, active mountain building is occuring, and the Akaishi Ranges are rising 3 mm/a. Unlike the episodic aseismic uplift of the Transverse Ranges of southern California, movements here have been relatively uniform. It seems likely that an increase in the tilt rate of the Suruga coast recognized since ∼1973 is part of a long-term readjustment to the great 1944 Tonankai earthquake. Data show that a monotonic increase has occurred since at least 1949, and similar effects are seen adjacent to the 1944 rupture zone over 200 km southwest along the Nankai Trough.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB086iB10p09237","issn":"01480227","usgsCitation":"Thatcher, W., and Matsuda, T., 1981, Quaternary and geodetically measured crustal movements in the Tokai District, Central Honshu, Japan: Journal of Geophysical Research Solid Earth, v. 86, no.

Although we found no evidence for nuclides characteristic of a ruptured fuel element, we did find nuclides characteristic of routine operations. Despite the TMI incident, more than 95% of the total 134Cs input to the Susquehanna has been a result of controlled low-level releases from the PB site. 134Cs activity released into the river is effectively trapped by sediments with the major zones of reactor-nuclide accumulation behind Conowingo Dam and in the upper portions of Chesapeake Bay.

Cellulose and other carbohydrates, the major components of Holocene wood, have been shown to be gradually hydrolyzed or otherwise lost under the conditions of burial. Lignin structures, however, are preserved relatively unchanged and become concentrated by difference as the carbohydrates disappear. Thus, a fragment of coalified wood isolated from a Miocene brown coal was found to be still composed of approximately 75% lignin and 25% cellulose.

Correlations of valley presence with other surface features show that almost all valleys are in the old cratered terrain. preferentially in areas of low albedo, low violet/red ratios, and high elevation. The networks are open, the individual drainage basins are small relative to Earth, and large distances separate the basins, features which all suggest an immature drainage system. The simplest explanation of the correlations and the restriction of valley networks to old terrain is that the channels themselves are old, and that the climatic conditions necessary for their formation did not prevail for long after the decline in the cratering rate around 3.9 billion years ago. Two types of outflow channel are distinguished: unconfined, in which broad swaths of terrain are scoured, and confined, in which flow is restricted to discrete channels. The outflow channels have a wide range of ages and may form under present climatic conditions. Fretted channels are largely restrited to two latitude belts centered on 40°N and 45°S, where relatively rapid erosion along escarpments results from mass wasting.

The associated megaflora, plants from coal balls, and vertebrate and invertebrate faunas demonstrate that the material is Famennian; the microflora indicates a more specific Fa2c age. Consequently, these seeds predate Archaeosperma arnoldii1 from the Fa2d of northeastern Pennsylvania, the oldest previously reported seed. By applying precision fracture, transfer, de??gagement, and thin-section techniques to selected cupules from the more than 100 specimens on hand, we have determined the three-dimensional morphology and histology of the seeds (Fig. 2a-h, k) and cupule systems.

Optimization of conditions in the chromatographic systems to attain desirable baseline separations of the components of interest is described. The minimum detectable quantities as determined are in the neighborhood of 10 ng for the quaternary ammonium salts by HPLC-UV detection, 0.1 ng for the cyanamide derivatives of the salts by GC-alkaline flame-ionization detection and 1–2 pg for the trichloroethyl carbamate derivatives of the salts by GC-electron-capture detection. In conjunction with cation-exchange chromatography for sample enrichment and purification, the glass capillary GC and ion-pair reversed-phase HPLC methods presented here are particularly suitable to separate and simultaneously analyze for the aryloxyethoxyethyl benzyl dimethyl ammonium compounds concerned in environmental samples.

Allelic variability at isocitrate dehydrogenase and glycerol-3-phosphate dehydrogenase loci was recorded for samples of lake herring (<i>Coregonus artedii</i>), bloater (<i>C. hoyi</i>), kiyi (<i>C. kiyi</i>), and shortjaw cisco (<i>C. zenithicus</i>) from five Lake Superior localities. The observed frequencies of genotypes within each subsample did not differ significantly from those expected on the basis of random mating, and suggested that each subsample represented either a random sample from a larger randomly mating population or an independent and isolated subpopulation within which mating was random. Significant contingency X<sup>2</sup> values for comparisons between both localities and species suggested that more than one randomly mating population occurred among the Lake Superior ciscoes, but did not reveal how many such populations there were. In contrast to the genetic results of this study, morphology seems to be a better descriptor of cisco stocks, and identification of cisco stocks and species will still have to be based on morphological criteria until more data are forthcoming. Where several species are sympatric, management should strive to preserve the least abundant. Failure to do so could result in the extinction or depletion of the rarer forms.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Canadian Journal of Fisheries and Aquatic Sciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"NRC Research Press","publisherLocation":"Ottawa, Ontario","doi":"10.1139/f81-227","usgsCitation":"Todd, T.N., 1981, Allelic variability in species and stocks of Lake Superior ciscoes (Coregoninae): Canadian Journal of Fisheries and Aquatic Sciences, v. 38, no. 12, p. 1808-1813, https://doi.org/10.1139/f81-227.","productDescription":"p. 1808-1813","startPage":"1808","endPage":"1813","numberOfPages":"5","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":133296,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":266958,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1139/f81-227"}],"volume":"38","issue":"12","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae0e4b07f02db687e9f","contributors":{"authors":[{"text":"Todd, Thomas N.","contributorId":42547,"corporation":false,"usgs":true,"family":"Todd","given":"Thomas","email":"","middleInitial":"N.","affiliations":[],"preferred":false,"id":308495,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
