Excerpt: ...ledges claiming to be silver-bearing of high grade ores were located during the past summer, but, like the gold prospects, have slipped away from the attention and have become completely eclipsed by the recent discoveries of tin, which gave rise to the next and more enduring excitement. Much has been claimed by the owners of the tin locations, the realization of one quarter of which would place it at the head of all the rich mineral discoveries made on this continent. That tin may be present to the amount of one, two or three per cent. is just possible, but there can be no doubt that the current reports of 70, 30, and even 15 per cent., are gross exaggerations. The actual presence of tin in most of the samples of so-called tin stone paraded about town is only presumptive, for assays and tests made by several of the most competent assayers of Salt Lake City show not even traces. _ It has been confidently affirmed by interested tin enthusiasts that specimens of mineral identical in character with those tested here, have yielded in the laboratories of able chemists in New York and Washington, as much as 30 and even 70 per cent. of tin. Such statements, however, cannot possibly deceive, as the simple test of gravity alone, will convince any one with ordinary experience in the handling of minerals, that but a low percentage of such a heavy metal as tin can possibly be contained in the vein stuff extracted from the claims in Weber district. It is further asserted that certain Cornishmen, professional adepts, have extracted from 15 to 18 per cent., by simply washing away the gangue, and fusing the concentrated stuff in the fire of a blacksmith's forge, while another expert of still more novel and inventive genius, reduces the ore and...

Available in PDF, EPUB and Kindle. Book excerpt: Whether you are a geologist, history buff, or rockhound, this booklet will be a helpful guide to Utah?s mining districts. The booklet is divided up into three parts: the first part provides general information on what a mining district is, how many mining districts are in Utah, types of mineral deposits found at these districts, and landownership issues. The second part includes individual mining-district discussions containing information on location, production, history, geology, mineralogy, and current/future operations. The third part includes a glossary of geologic terms and other useful resources in the appendices, such as a descriptive list of minerals found in the districts, geologic time scale, and a list of mineral resources of the mining districts.

Available in PDF, EPUB and Kindle. Book excerpt: Since the Arab oil embargo of 1974, it has been clear that the days of almost limitless quantities of low-cost energy have passed. In addition, ever worsening pollution due to fossil fuel consumption, for instance oil and chemical spills, strip mining, sulphur emission and accumulation of solid wastes, has, among other things, led to an increase of as much as 10% in the carbon dioxide content of the atmosphere in this century. This has induced a warming trend through the 'greenhouse effect' which prevents infrared radiation from leaving it. Many people think the average planetary temperatures may rise by 4°C or so by 2050. This is probably true since Antarctic ice cores evidence indicates that, over the last 160000 years, ice ages coincided with reduced levels of carbon dioxide and warmer interglacial episodes with increased levels of the gas in the atmosphere. Consequently, such an elevation of temperature over such a relatively short span of time would have catastrophic results in terms of rising sea level and associated flooding of vast tracts of low-lying lands. Reducing the burning of fossil fuels makes sense on both economic and environmental grounds. One of the most attractive alternatives is geothermal resources, especially in developing countries, for instance in El Salvador where geothermal energy provides about a fifth of total installed electrical power already. In fact, by the middle 1980s, at least 121 geothermal power plants were operating worldwide, most being of the dry steam type.
