Regional resource depletion and industry activity: The case of oil and gas in the Gulf of Mexico
E. D. Attanasi
1986, Socio-Economic Planning Sciences (20) 283-289
Stable and declining oil and gas prices have changed the industry's price expectations and, along with depletion of promising exploration prospects, has resulted in reduced exploration. Even with intensive additional exploration, production in most U.S. areas is expected to decline. What does this imply for the drilling and petroleum industry...
Cluster molecular orbital description of the electronic structures of mixed-valence iron oxides and silicates
David M. Sherman
1986, Solid State Communications (58) 719-723
A molecular orbital description, based on spin-unrestricted Xα-scattered wave calculations, is given for the electronic structures of mixed valence iron oxides and silicates. The cluster calculations show that electron hopping and optical intervalence charge-transger result from weak FeFe bonding across shared edges of FeO6 coordination polyhedra. In agreement with Zener's double exchange...

A. F. Glazner, J. E. Nielson, K. A. Howard, D. M. Miller
1986, Geology (14) 840-843
The Peach Springs Tuff is a distinctive early Miocene ignimbrite deposit that was first recognized in western Arizona. Recent field studies and phenocryst analyses indicate that adjacent outcrops of similar tuff in the central and easten Mojave Desert may be correlative. This proposed...
Magmatic inclusions in silicic and intermediate volcanic rocks
Charles R. Bacon
1986, Journal of Geophysical Research B: Solid Earth (91) 6091-6112
Fine‐grained ellipsoidal inclusions from a few millimeters to over l m in size are present in many intermediate to silicic lava flows and domes. Only recently has it become widely accepted that such inclusions are chilled blobs of magma. Their magmatic origin is manifested by vesicularity and high groundmass porosity,...

Runoff quantity and quality data from four urban basins in south Florida were analyzed to determine the entrainment of total nitrogen, total phosphorus, total carbon, chemical oxygen demand, suspended solids, and total lead within the stormwater runoff. Land use of the homogeneously developed basins are residential (single family), highway, commercial,...
Drought of 1980-82 in southeast Florida with comparison to the 1961-62 and 1970-71 droughts
B.G. Waller
1985, Water-Resources Investigations Report 85-4152
South-central Florida (the Kissimmee Basin) experienced a severe drought during 1980-82, causing Lake Okeechobee--the largest surface-water storage area in south Florida--to reach the lowest stage ever recorded, 9.75 feet above sea level, on July 29, 1981. A prolonged period of deficient rainfall extended from June 1980 to March 1982. On...

James York, Frederic H. Wilson, Bruce M. Gamble
1985, Circular 945
The tectonic evolution of the Alaska Peninsula makes it a likely area for the discovery of significant mineral deposits. However, because of problems associated with remoteness and poor weather, little detailed mineral exploration work has been carried on there. This study focuses on using Landsat multispectral scanner data for the...
