Instead, basement morphology typical of the Murray fracture zone ends where its known magnetic and bathymetric expression dies out. Similarly, east-west Transverse Range structures change direction so that they are parallel to the northwest trend of the coast rather than crossing the continental shelf and slope. The lack of continuity suggests an independent development of the Transverse Ranges since at least mid-Tertiary time along an older structural trend continuous with the Murray fracture zone. Possibly a fundamental lineament in the crust, an extension of the Murray, inactive since at least the mid-Tertiary, provided a convenient trend for development of the Transverse Ranges in response to deformation along the San Andreas fault system. The Murray fracture zone is thought by some authors to be a transform-fault. The transform-fault hypothesis alleviates some difficulties that arise in explaining the origin of the zone by transcurrent faulting but equivalent uncertainties seem to accompany the newer explanation.</p></div></div></div><ul id=\"issue-navigation\" class=\"issue-navigation u-margin-s-bottom u-bg-grey1\"></ul>","language":"English","publisher":"Elsevier","doi":"10.1016/0025-3227(69)90020-6","issn":"00253227","usgsCitation":"von Huene, R.E., 1969, Geologic structure between the Murray fracture zone and the Transverse Ranges: Marine Geology, v. 7, no. 6, 23 p., https://doi.org/10.1016/0025-3227(69)90020-6.","productDescription":"23 p.","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":219329,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"7","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a21e8e4b0c8380cd56bc4","contributors":{"authors":[{"text":"von Huene, Roland E. 0000-0003-1301-3866 rvonhuene@usgs.gov","orcid":"https://orcid.org/0000-0003-1301-3866","contributorId":191070,"corporation":false,"usgs":true,"family":"von Huene","given":"Roland","email":"rvonhuene@usgs.gov","middleInitial":"E.","affiliations":[{"id":7065,"text":"USGS emeritus","active":true,"usgs":false},{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":false,"id":357087,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The observed isotope ratios can be explained by mixing of surface water and diagenetically modified sea water, accompanied by a process which enriches the heavy oxygen isotope. Mass balances for deuterium and total dissolved solids in the western Canada sedimentary basin demonstrate that the present distribution of deuterium in formation waters of the basin can be derived through mixing of the diagenetically modified sea water with not more than 2.9 times as much fresh water at the same latitude, and that the movement of fresh water through the basin has redistributed the dissolved solids of the modified sea water into the observed salinity variations. Statistical analysis of the isotope data indicates that although exchange of deuterium between water and hydrogen sulphide takes place within the basin, the effect is minimized because of an insignificant mass of hydrogen sulphide compared to the mass of formation water. Conversely, exchange of oxygen isotopes between water and carbonate minerals causes a major oxygen-18 enrichment of formation waters, depending on the relative masses of water and carbonate. Qualitative evidence confirms the isotopic fractionation of deuterium on passage of water through micropores in shales.</p></div></div></div>","language":"English","publisher":"Elsevier","doi":"10.1016/0016-7037(69)90178-1","issn":"00167037","usgsCitation":"Hitchon, B., and Friedman, I., 1969, Geochemistry and origin of formation waters in the western Canada sedimentary basin-I.

Injection of insulin concurrently with refeeding also failed to alter the specific activity of the enzyme in trout. The absence of a dietary or insulin influence on the teleost enzyme system is to be contrasted with studies in mammals in which the activity of hepatic glucose 6-P dehydrogenase was markedly stimulated after refeeding starved animals or injection of insulin.Ingestion of the pesticide DDT by juvenile coho salmon or adult rainbow trout also had no effect on the specific activity of liver glucose 6-P dehydrogenase and DDT failed to inhibit the rainbow trout enzyme in vitro. These results also differ considerably from those found in higher animals.These results suggest that the glucose 6-P dehydrogenase enzyme in teleosts may be under a different type of regulatory control from that found in mammals.</span></p>","language":"English","publisher":"NRC Research Press","doi":"10.1139/f69-302","usgsCitation":"Buhler, D.R., and Benville, P., 1969, Effect of feeding and of DDT on the activity of hepatic glucose 6- phosphate dehydrogenase in two salmonids: Journal of the Fisheries Research Board of Canada, v. 26, no. 12, p. 3209-3216, https://doi.org/10.1139/f69-302.","productDescription":"8 p.","startPage":"3209","endPage":"3216","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"links":[{"id":321700,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"26","issue":"12","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5746ccb7e4b07e28b662dc95","contributors":{"authors":[{"text":"Buhler, Donald R.","contributorId":169619,"corporation":false,"usgs":false,"family":"Buhler","given":"Donald","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":630327,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Benville, P.","contributorId":169623,"corporation":false,"usgs":false,"family":"Benville","given":"P.","email":"","affiliations":[],"preferred":false,"id":630328,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

He conceived of three different historical relationships between rivers and structural features: (1) Newly uplifted land surfaces have rivers that flow down the initial slope of the uplift; these relationships he termed consequent. (2) A river may be older than an uplift that it crosses because it has been able to maintain its course by eroding downward as the uplift progresses; this relationship he named antecedent. (3) An uplifted block may have been buried by younger deposits upon which a river becomes established. The river, in cutting downward, uncovers the uplifted block and becomes incised into it; this relationship he called superimposed.</p><p>The geologic history of the Colorado River involves all three relationships. In addition, although the position of the river course through a particular structural barrier may have been the result of superposition, the depth of the canyon at that point may be largely due to renewed uplift of the barrier; such deepening of the canyon, therefore, is due to antecedence. The problem of the Colorado River remains today very much as G. K. Gilbert stated it nearly 100 years ago: \"How much is antecedent and how much is superimposed?\" The question must be asked separately for each stretch of the river. </p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"The Colorado River region and John Wesley Powell (Professional Paper 669)","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"language":"English","publisher":"U.S. Government Printing Office","publisherLocation":"Washington, D.C.","doi":"10.3133/pp669C","usgsCitation":"Hunt, C.B., 1969, Geologic history of the Colorado River: Chapter C in <i>The Colorado River region and John Wesley Powell (Professional Paper 669)</i>: U.S. Geological Survey Professional Paper 669, iv, 72 p., https://doi.org/10.3133/pp669C.","productDescription":"iv, 72 p.","startPage":"59","endPage":"130","costCenters":[],"links":[{"id":338556,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":338554,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/pp/0669/report.pdf#page=71"}],"country":"United States","otherGeospatial":"Colorado River","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58dcc824e4b02ff32c685772","contributors":{"authors":[{"text":"Hunt, Charles B. cdhunt@usgs.gov","contributorId":16079,"corporation":false,"usgs":true,"family":"Hunt","given":"Charles","email":"cdhunt@usgs.gov","middleInitial":"B.","affiliations":[],"preferred":false,"id":686766,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
