Gold- and silver-bearing veins occur in three northwest-trending fault systems, the Sierra, Veta Madre, and La Luz. Orebodies in the Sierra and Veta Madre were arbitrarily divided into two groups, those that occur above the 2,100-meter level called "

Sulfur in ore deposits from igneous rocks derived from mantle should have isotopic composition of meteorite sulfur. This does not give a unique solution, because under some conditions volcanic, sedimentary, and biogenic sulfur may also have this comp

Gold is a trace constituent (average 0.015 ounces per ton) in the matrix of virtually all the 28 conglomerate beds exposed at the mine, and economic concentrations occur in 10 beds that are interpreted as giant foreset beds. The greatest concentratio

Primary banded iron formation near Fort Gouraud, Mauritania, contains about 30 percent iron. Four kinds of hematite concentration (roughly 65 percent iron) are recognized. 9Deep hematite ore9 is believed to be syngenetic, since it is chemically simil

The Lamaque and Sigma ore zones are composed of a multiplicity of gold-bearing quartz veins extending vertically to depths greater than 4,000 feet. The mines are about 2,500 feet apart horizontally and they are separated by a steeply dipping fault zo

The Red Lake greenstone belt is Archaean in age (older than 2.5 billion years) and is located in the Superior province of the Canadian Precambrian Shield. It is a fairly typical greenstone belt, being composed of a complex assemblage of lavas, sedime

Studies were made of the S/sup 32//S/sup 34/ ratios in four large basic sills presumably of deep-seated origin. The average ratio for these sills was determined by weighting each sample according to sulfur content and in accordance with the thickness
