Size of branch was defined by branch order, or its position in the hierarchy of tributaries. It was found that, as in river drainage nets, there is a definite logarithmic relation between branch order and lengths and numbers. This definite relation is quantitatively comparable, within limits, among river networks, tree branching systems, and several random-walk models in both two and three dimensions. Such a relation appears to be the most probable under the applicable constraints. Moreover the most probable arrangement appears to minimize the total length of all stems in the branching system within other constraints and so, to that extent, achieves a certain efficiency.</p>","largerWorkTitle":"Journal of Theoretical Biology","language":"English","publisher":"Elsevier","doi":"10.1016/0022-5193(71)90192-5","issn":"00225193","usgsCitation":"Leopold, L.B., 1971, Trees and streams: The efficiency of branching patterns: Journal of Theoretical Biology, v. 31, no. 2, p. 339-354, https://doi.org/10.1016/0022-5193(71)90192-5.","productDescription":"16 p.","startPage":"339","endPage":"354","costCenters":[],"links":[{"id":219004,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"31","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb7a9e4b08c986b3273f1","contributors":{"authors":[{"text":"Leopold, Luna Bergere","contributorId":93884,"corporation":false,"usgs":true,"family":"Leopold","given":"Luna","email":"","middleInitial":"Bergere","affiliations":[],"preferred":false,"id":358819,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Calcite has compositions from CaCO<sub>3</sub><span>&nbsp;</span>to Ca<sub>0.5</sub>Mg<sub>0.5</sub>CO<sub>3</sub>.

The Ca-Mg carbonates form in isotopic equilibrium and thermodynamic disequilibrium from dispersion of Ca<sup>2+</sup>-rich water into CO<sub>3</sub><sup>2−</sup>-rich water within the alluvium.

The fossil flora is of great biogeographic interest because of its position (Fig. 1) in a tundra region about 250 km east of Bering Strait, 75 km south of the Arctic Circle, and 65 km west of the northwestern limit of spruce-birch forest. It provides insight into the history of the development of the circumpolar boreal forest (taiga). A rich arthropod fauna casts light on the phylogeny of several modern insect genera and on the origin of modern tundra faunas.

Smoothed depth-diameter curves for 41 large martian craters photographed by Mariner IV inflect at a crater diameter of 10–20km in a manner similar to curves for lunar craters. Below 10–20km, both depth-diameter curves are linear with a slope of roughly 1.0; above this threshold range, the curves assume a much lower slope. Diminution of lunar crater depth-diameter ratios with age indicates that the shapes of lunar and, by inference, martian craters have changed systematically since formation. Martian craters sampled here are shallower than most pre-Imbrian lunar craters. By analogy with the Moon, martian craters seem both to vary in initial shape according to the energy of the impact that formed them and to have been modified subsequently by endogenic and surface processes. A proposed model for the geologic development of large martian and lunar craters outlines a time- dependent sequence of events. Craters which have undergone rapid isostatic adjustment on the Moon have distinctive morphologies and occur preferentially along mare basin-upland margins.</p></div></div></div><ul id=\"issue-navigation\" class=\"issue-navigation u-margin-s-bottom u-bg-grey1\"></ul>","language":"English","publisher":"Elsevier","doi":"10.1016/0019-1035(71)90117-5","issn":"00191035","usgsCitation":"Pike, R., 1971, Genetic implications of the shapes of martian and lunar craters: Icarus, v. 15, no. 3, p. 384-395, https://doi.org/10.1016/0019-1035(71)90117-5.","productDescription":"12 p.","startPage":"384","endPage":"395","numberOfPages":"12","costCenters":[],"links":[{"id":218791,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"15","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a157ae4b0c8380cd54e2c","contributors":{"authors":[{"text":"Pike, R.J.","contributorId":72814,"corporation":false,"usgs":true,"family":"Pike","given":"R.J.","email":"","affiliations":[],"preferred":false,"id":358660,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The supernatant solutions were removed from the clay minerals and analyzed for SiO<sub>2</sub>, Al<sub>2</sub>O<sub>3</sub>, CaO, MgO, Na<sub>2</sub>O, and K<sub>2</sub>O. All the solutions removed some SiO<sub>2</sub>, Al<sub>2</sub>O<sub>3</sub>, and Fe<sub>2</sub>O<sub>3</sub> from the samples, but the quantities were small. Sodium hydroxide attacked the kaolin group minerals more strongly than it did montmorillonite, metabentonite, or illite. Halloysite was more strongly attacked by hydrochloric acid than was any of the other experimental minerals. Hydrochloric acid removed iron oxide coatings from soil clay minerals, but acetic acid did not remove them completely. The samples most strongly attacked by HCl and NaOH were examined by X-ray diffraction. Acid treatment did not destroy the structure of the clays, but the halloysite structure was partially destroyed. Sodium hydroxide attacked the halloysite structure, as shown by chemical analysis and X-ray diffraction. These experiments show that treatment in dilute acids has no harmful effect in the preparation of clays for X-ray diffraction. Acetic acid is preferred to hydrochloric acid for this purpose. Hydrochloric acid cleans clay minerals by removing free iron oxide from the surface; acetic acid is less effective.</p>","language":"English","publisher":"The Clay Minerals Society","doi":"10.1346/CCMN.1971.0190508","usgsCitation":"Carroll, D., and Starkey, H.C., 1971, Reactivity of clay minerals with acids and alkalies: Clays and Clay Minerals, v. 19, no. 5, p. 321-333, https://doi.org/10.1346/CCMN.1971.0190508.","productDescription":"13 p.","startPage":"321","endPage":"333","costCenters":[],"links":[{"id":219754,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"19","issue":"5","noUsgsAuthors":false,"publicationDate":"2024-07-01","publicationStatus":"PW","scienceBaseUri":"505a958fe4b0c8380cd81ac5","contributors":{"authors":[{"text":"Carroll, Dorothy","contributorId":38534,"corporation":false,"usgs":true,"family":"Carroll","given":"Dorothy","email":"","affiliations":[],"preferred":false,"id":358757,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Starkey, Harry C.","contributorId":175349,"corporation":false,"usgs":false,"family":"Starkey","given":"Harry","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":358758,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

To save time in washing samples, a washing 'basket' was designed which accomadates a Ponar dredge.
