Precambrian Geology In Humboldt Township, Marquette County, Michigan, Peter D. Rowley Jan 1965

Precambrian Geology In Humboldt Township, Marquette County, Michigan, Peter D. Rowley

Journal of the Minnesota Academy of Science

ABSTRACT-The present study involved investigation of gneissic granite, migmatite, basic dikes, and faults in part of the Southern Complex of Michig.an. The average strike of the foliation of the gneissic granite based upon the orientation of feldspar phenocrysts is N. 60° w·;, the strike of the major dike set is between N. 30° W. and N. 60° W., the average strike of the fault zones-is N. 52° W., and a two-mile long body of migmatite trends about N. 57° W. The known history starts in the early Precambrian, when gneissic granite was emplaced and formed migmatites by incorporation of wall-rock …

Miocene Mammals And Central American Seaways, Frank C. Whitmore Jr., Robert H. Stewart Jan 1965

Miocene Mammals And Central American Seaways, Frank C. Whitmore Jr., Robert H. Stewart

United States Geological Survey: Staff Publications

The fossil mammal faunas of North and South America indicate that the two continents were separated from Paleocene or earlier time until the late Pliocene. Unfortunately our almost complete ignorance of the Tertiary land mammals of Central America, the geology of this large area, makes reconstruction of the Tertiary zoogeography of the region between the continents an exercise involving considerable speculation.

Available Water Supply Of The Las Vegas Ground-Water Basin Nevada, Glenn Thomas Malmberg Jan 1965

Available Water Supply Of The Las Vegas Ground-Water Basin Nevada, Glenn Thomas Malmberg

Publications (WR)

The Las Vegas ground-water basin as described in this report includes the southern part of Indian Spring Valley, Three Lakes Valley, the northern half of Ivanpah Valley, and Las Vegas Valley. These valleys in part are inferred to form a hydrologic unit that includes an area of about 3,000 square miles in the southern part of Clark County, Nev.

The valleys forming the Las Vegas ground-water basin are broad structural depressions surrounded by mountains. The climate of the region is arid, and precipitation in the basin lowlands rarely exceeds 5 inches per year. Drainage is interior except for occasional Hood …


Petrology And Mineralogy Of The "Old Workings Area," El Salvador, Chile, Bertis James Vander Schaaff Jan 1965

Petrology And Mineralogy Of The "Old Workings Area," El Salvador, Chile, Bertis James Vander Schaaff

Masters Theses

"The 'Old Workings Area,' so called for its early mining by the Incas, is located 4 1/2 miles northeast of the El Salvador Porphyry copper deposit, the third largest copper producer in Chile. The area mapped in this study is shown to consist of rhyolite pebble conglomerate, two volcanic flows, andesite and rhyolite porphyry, and two intrusions. Quartz porphyry and tourmaline-bearing breccia. Petrographic study of surface and drill core rock samples confirms the field nomenclature used for the five rock types. All of the rock types are altered, but the quartz porphyry and andesite are the most intensely altered. Both …

Second Bibliography And Index For The Philosophy Of Geology, Claude C. Albritton Jr. Aug 1964

Second Bibliography And Index For The Philosophy Of Geology, Claude C. Albritton Jr.

Journal of the Graduate Research Center

The body of writings on the philosophy and history of geology has grown in a remarkable way since the end of the Second World War. There is no obvious explanation for this quickening of interest in what are surely the most academic aspects of a science best known for its practical applications. Influences arising both from within and from outside the geological profession have probably been responsible. It is a matter of record that many departments of geology, upon resuming full-time operations after the war, decided not to go on moving in the old curricular ruts. The new courses, even …

Determining The Force Of Friction In A Simple Machine, Joseph J. Snoble Jan 1964

Determining The Force Of Friction In A Simple Machine, Joseph J. Snoble

Iowa Science Teachers Journal

Too often a science unit on simple machines consists of a discussion of ideal mechanical advantage (I.M.A.) and actual mechanical advantage (A.M.A.) in pulley systems and inclined planes, without really emphasizing the role of friction.


"Live" Geology, Mary Isidore Rohan Jan 1964

"Live" Geology, Mary Isidore Rohan

Iowa Science Teachers Journal

How old is the earth? Where did it come from? How was it made? Junior high students are determined to solve all life's mysteries and therefore geology with its wealth of clues is a likely target for their curiosity. The earth sciences seem to hold an almost mystical fascination for the junior high age child possibly because the adolescent is beginning to realize he is part of the whole universe and not just of a family, and is using his powers of observation to see what this universe holds.

Structural And Magnetic Characteristics Of The Belton Anomaly, Cass County, Missouri, Nagib Chamon Jan 1964

Structural And Magnetic Characteristics Of The Belton Anomaly, Cass County, Missouri, Nagib Chamon

Masters Theses

"A vertical intensity magnetic survey of approximately 156 square miles in Cass County, central-west Missouri, revealed a broad circular anomaly whose magnetic relief exceeds 1000 gammas. Surface rocks are very gently inclined and are of Pennsylvanian age. Crystalline basement rocks are at a depth of approximately 2400 feet. Analysis of the data shows that the Belton anomaly consists of discontinuous smaller magnetic anomalies surrounding the central part of this broad anomaly. The central area of the Belton anomaly is occupied by a magnetic low. Analytical calculation showed that the source of the magnetic disturbance is at least 3650 feet below …

Charophytes Of Pleistocene Age From Delta And Denton Counties, Texas, Harold E. Schlichting Jr.

Journal of the Graduate Research Center

Collections of Chara oogonia from late Pleistocene alluvium beneath the floodplain of the North Fork of the Sulphur River near Ben Franklin (Delta County), and from the second terrace above Clear Creek (Denton County) were studied. The radiocarbon dates of the Sulphur River deposits are 10,000-11,000 B.P., while those of the Clear Creek deposits are about 28,000 B.P.
