Wind Erosion In The Jerramungup Area 1980-1981, Bryan J. Goddard, M G. Humphry, D J. Carter Jan 1981

Wind Erosion In The Jerramungup Area 1980-1981, Bryan J. Goddard, M G. Humphry, D J. Carter

Resource management technical reports

An investigation of the wind erosion problem at Jerramungup was conducted by on-farm survey and Landsat interpretation from September to November 1981. Sandblasting and wind erosion were estimated to have seriousloy affected some 44,000 ha in 1980 and over 64,000 ha in 1981. The 1981 damage estimate is conservative, because a much greater area of pasture land was affected by erosion in May-July but achieved vegetative cover by later winter.

Federal Lands, Laws and Policies and the Development of Natural Resources: A Short Course (Summer Conference, July 28-August 1)

Even before the [Natural Resources Law] Center was established [in the fall of 1981], the [University of Colorado] School of Law was organizing annual natural resources law summer short courses. To date four programs have been presented:

- July 1980: "Federal Lands, Laws and Policies and the Development of Natural Resources"

- June 1982: "New Sources of Water for Energy Development and Growth: lnterbasin Transfers"

- June 1983: "Groundwater: Allocation, Development and Pollution"

(Reprinted from Resource Law Notes, no. 1, Jan. 1984, at 1.)

A Gering Formation (Miocene) Pumice Conglomerate And Associated Beds From Broadwater, Nebraska, Robert F. Diffendal Jr. Mar 1979

A Gering Formation (Miocene) Pumice Conglomerate And Associated Beds From Broadwater, Nebraska, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

The Mitchell Pass Member of the Gering Formation was defined by Vondra, Schultz, and Stout in 1969 on the basis of exposures in the Wildcat Ridge area of western Nebraska. The basal part of the member in many areas of Wildcat Ridge is a pumice-pebble conglomerate bed. A newly discovered pumice-pebble conglomerate locality occurs north of Broadwater, Nebraska, some twenty miles east of the easternmost previously reported exposure of the pumice conglomerate at Redington Gap on Wildcat Ridge. Pumice samples from Redington Gap and Broadwater have the same index of refraction and similar inclusions. Beds above the conglomerate and below …

The Rush Creek Structure, Garden County, Nebraska, Robert F. Diffendal Jr. Apr 1978

The Rush Creek Structure, Garden County, Nebraska, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

Detailed field mapping of surface outcrops in southern Garden County, Nebraska, has revealed a drop of 200 feet in three miles in the elevation of the contact between the Ogallala and pre-Ogallala (probably Brule) Formations exposed on the east side of Rush Creek. Beds of silt, sand, siltstone, and volcanic ash in the are a locally dip to the northwest at angles of up to 8½°. The contact between the two formations cannot be seen on the west side of Rush Creek but beds in the Ogallala Formation there dip to the north and northeast. The unusually long valley of …

Bulletin 4048: Salt Land And What To Do About It, C V. Malcolm Jan 1978

Bulletin 4048: Salt Land And What To Do About It, C V. Malcolm

Bulletins 4000 -

Since the development of land for agriculture in Western Australia more than 1 600 square kilometres of land has become too saline for normal crops and pasture, and the area is increasing. Much of this land was previously the most fertile crop land and on some farms salinity constitutes a major problem.

The purpose of this booklet is to impart an understanding of the nature and cause of saltland in Western Australia. The methods of treatment are explained in the light of this understanding. The material in the booklet is based on a detailed review 'Soil salinity in South Western …

Preliminary Report On A Pleistocene Pond, Garden County, Nebraska, Robert F. Diffendal Jr. May 1977

Preliminary Report On A Pleistocene Pond, Garden County, Nebraska, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

Discontinuous Pleistocene pond deposits occur along the valley sides of Dankworth Canyon southeast of Lewellen, Nebraska. At one locality the beds exposed in a channel-fill up to six feet thick consist of sand-sized carbonate-rich sediments deposited in alter nating light and dark layers resembling varves. Microscopic examination of disaggregated samples reveals that most of the sediment consists of sand and silt often cemented into tubes. Other components include several kinds of freshwater ostracodes, gastropods, charophyte gyrogonites, and bone-like debris probably from fish.

Microfossils From The Big Springs Limestone (Pennsylvanian) In Nebraska, Robert F. Diffendal Jr. May 1975

Microfossils From The Big Springs Limestone (Pennsylvanian) In Nebraska, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

Sand-sized residues from partial acetic acid digestion of three samples of the Big Springs Limestone Member of the Lecompton Limestone (Pennsylvanian) from two localities in Cass County, Nebraska, have yielded sixteen genera of microfossils from five major groups of organisms and numerous other whole and partial fossils from seven other groups not identified to the genus level. These fossils include: Protozoa (fusulinids*); Porifera (one spicule type); Bryozoa (two undetermined genera); Brachiopoda (fragments); Gastropoda (two undetermined forms); Ostracoda (Bairdia*, Hollinella*, Moorites*, and one undetermined genus); Crinoidea (whole and partial ossicles*); Echinoidea (whole and partial spines and spine bases*); Holothuroidea (Achistrum …

Microfossils From The Upper Severy Shale (Pennsylvanian) Near Dubois, Nebraska, Robert F. Diffendal Jr. May 1974

Microfossils From The Upper Severy Shale (Pennsylvanian) Near Dubois, Nebraska, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

Organic rich limestone nodules within the Severy Shale Formation collected directly above the Nodaway Coal Member near DuBois, Nebraska, have yielded a rich microflora and microfauna. The microflora includes Triletes megaspores, seeds, cuticle, and pieces of wood with well preserved structures. The microfaunal skeletal material is either partially or completely replaced by pyrite, marcasite, or, in rare cases, by sphalerite. The following major invertebrate groups and genera within these groups have been identified to date: Bryozoa (one undetermined genus); Brachiopoda (Juresania) ; Gastropoda (four undetermined genera); Ammonoidea (one undetermined genus); Ostracoda (Amphissites, Coryellites, Hollinella, Macrocypris); Echinoidea (five spine types); and …
