Distribution and origin of sulfur in Colorado oil shale Distribution and origin of sulfur in Colorado oil shale
The sulfur content of 1,225 samples of Green River oil shale from two core holes in the Piceance Creek Basin, Colorado, ranges from nearly 0 to 4.9 weight percent. In one core hole, the average sulfur content of a sequence of oil shale 555 m thick, which represents nearly the maximum thickness of oil shale in the basin, is 0.76 weight percent. The vertical distribution of sulfur through...

The Galilean satellite geological mapping program The Galilean satellite geological mapping program
The Galilean Satellite Geological Mapping Program was established to illuminate detailed geologic relations on the four large satellites of Jupiter. The program involves about 40 investigators from various universities, reseach institutes, and government offices in the United Sttes, England, Germany, and Italy. A total of 24 researchers have been assigned to map 10 quadrangles on...

The role of the USFWS geographic information system in coastal decisionmaking The role of the USFWS geographic information system in coastal decisionmaking
Unprecedented demand on coastal resources in the 1980's has generated a need for valid information and analyses to support wise management of the coastal zone. The National Coastal Ecosystems Team of the U.S. Fish and Wildlife Service recently implemented a geographic information system to enhance its ability to analyze and display environmental information about the coastal zone...

Chemical immobilization of North American mule deer Chemical immobilization of North American mule deer
The choice of agents for chemical immobilization of mule deer (Odocoileus hemionus) is a problem with a simple and effective solution, in my opinion. I recommend combinations of etorphine hydrochloride (M199©) and xylazine hydrochloride (Rompun©) administered intravenously and reversed intravenously. I have used this combination on hundreds of mule deer and have supervised its use on...

CHEMICAL STRUCTURES IN COAL: GEOCHEMICAL EVIDENCE FOR THE PRESENCE OF MIXED STRUCTURAL COMPONENTS. CHEMICAL STRUCTURES IN COAL: GEOCHEMICAL EVIDENCE FOR THE PRESENCE OF MIXED STRUCTURAL COMPONENTS.
The purpose of this paper is to summarize work on the chemical structural components of coal, comparing them with their possible plant precursors in modern peat. Solid-state **1**3C nuclear magnetic resonance (NMR), infrared spectroscopy (IR), elemental analysis and, in some cases, individual compound analyses formed the bases for these comparisons.
