Resource assessments, geologic deposit models, and offshore minerals with an example of heavy-mineral sands
A resource assessment method for offshore minerals based on descriptive and grade-tonnage models is proposed. Historical development and applications of this method are summarized. Based on this approach, descriptive and quantitative deposit models for strand-line titanium placer deposits have been developed. Descriptive statistics were also computed using the worldwide deposit data set upon which

White mica geochemistry of the Catheart Mountain porphyry copper deposit, Maine
White micas from hydrothermally altered and mineralized zones in the Catheart Mountain Cu-Mo porphyry deposit have regular compositional variations that are generally related to the contents of copper, total iron, and sulfur in the whole rock. Micas in unmineralized rocks exhibit no such relationship. White mica compositions reflect primarily the control imposed by the celadonitic substitution AII

Statistics of petroleum exploration in the non-Communist world outside the United States and Canada
The search for petroleum has expanded to include most countries in the world. From January 1, 1950, through 1980, about 160,000 crew months were spent in geologic and geophysical exploration in a study area that includes all nonCommunist countries outside the United States and Canada. By the end of 1982, almost 27,000 wildcat wells had been drilled in this study area; these and other pre-1983 well

Products of hexachlorocyclopentadiene (C-56) in aqueous solution
The photodegradation and degradation products of hexachlorocyclopentadiene (C-56) in aqueous solutions were studied in the laboratory. In each case, the half-life of C-56 was less than 4 min when exposed to sunlight. At least eight degradation products were positively or tentatively identified: 2,3,4,4,5-Pentachloro-2-cyclopentenone, hexachloro-2-cyclopentenone and hexachloro-3-cyclopentenone were

Pressure sensitivity of low permeability sandstones
Detailed core analysis has been carried out on 32 tight sandstones with permeabilities ranging over four orders of magnitude (0.0002 to 4.8 mD at 5000 psi confining pressure). Relationships between gas permeability and net confining pressure were measured for cycles of loading and unloading. For some samples, permeabilities were measured both along and across bedding planes. Large variations in st

Source of lead and mineralizing brines for rossie-type Pb-Zn veins in the Frontenac axis area, New York ( USA).
Veins composed mainly of calcite and some galena, sphalerite, fluorite, and other minerals are widespread in the Frontenac axis area of New York and Ontario. In New York, the veins (Fig. 1) occur mainly west and northwest of Gouverneur (Brown, 1983). The veins, mined in the 1800s for lead, were first described by Emmons (1838). Smyth (1903) called these the "Rossie lead veins," a name now used loc

Bibliography and index of the geology of the Creede mining district and vicinity
This bibliography and index of the geology of the Creede mining district and vicinity was prepared in support of the increased number of studies being conducted in conjunction with the proposed deep drilling program at Creede. It was our intent to include in this compilation all papers, abstracts, and maps which contribute any information pertaining to the geology of the Creede district. Thus, ref

Aluminum in hornblende: an empirical igneous geobarometer.
Electron-microprobe analyses of hornblendes from five calc-alkaline plutonic complexes representing low- and high-pressure regimes define a tightly clustered linear trend in terms of total Al (AlT) and tetrahedral Al (Aliv) contents. Data collated from the literature on calcic amphiboles from other plutonic complexes and from phase equilibrium experiments using natural rocks or synthetic analogue
