Book Description
This volume presents a comprehensive and systematic account of diverse types of Indian placer deposits. It deals with the location, development and establishment of placer mineral resources through systematic field- and laboratory-based geological, geo-informatics, geomorphological, geophysical, petro-mineralogical and geochemical exploration, drilling, mining, evaluation, resource-establishment, and mineral processing. The placer deposits discussed here include gold, diamond, rare metals, rare earths and shoreline/inland heavy mineral sands.

Book Description
This volume presents a brief introduction to the Rare Earth Elements (REE) and their discovery, mineralogy, deposit types and applications. The book focusses on the aspects of both natural and industrial REE resources of India. It covers geological, structural, geochemical, petrological, mineralogical and genetic aspects of the natural deposits, and provides an account of the available industrial sources. The relative merits and potential of the several resources for future development and directions for inputs in REE exploration are discussed at the end of the monograph.

Book Description
Excerpt from Placer Gold Deposits of Nevada Following the discovery of placers at Gold Canyon, placer discoveries in Nevada were broadly in three periods: the 1860's to 1880's, when many small deposits throughout the State were discovered and sporadically worked and several large placers were discovered and extensively worked; the short period between 1906 and 1910, when very rich placers were dis covered at Lynn, Battle Mountain, Manhattan, and Round Mountain; the early 1930's, when economic conditions created by the depression caused a renewed interest in placer mining, and many individuals sought, and a few discovered, new placer areas throughout the State. The location of the placers described in this report is shown on plate 1. Very little factual information can be found about the early periods of placer mining in Nevada. For many placers, the only reports available are hearsay estimates of production and speculations about the extent of the placer ground based on remnants of placer pits, shafts, and other workings. Many of the placers said to have had a high production between 1860 and 1890 were worked by Chinese miners who came to Nevada dur ing the building of the railroads and stayed on to work at mining and other activities. The Chinese were reputed to be secretive with their earnings from the placers and did not ship the gold to the mint by Wells Fargo or other shippers. They worked the gravels very thoroughly in areas where American miners did not wish to expend great labor to win the gold. The placers in the Sierra and Spring Valley districts, Pershing County, were worked by Chinese miners; they have a very high estimated production before 1900 and a comparatively low known production since that time.

Book Description
This handbook summarizes the main advances in our understanding of marine minerals and concentrates on the deposits of proven economic potential. In cases where our knowledge may be too limited to allow defining of their economic potential, those minerals are covered regionally or by deposit type. Handbook of Marine Mineral Deposits is divided into three sections; Marine placers, manganese nodules and crusts, and deep-sea hydrothermal mineralization. All of these mineral deposits have great potential importance to economic geologists and marine mines. Edited by an acknowledged expert in the field, this handbook includes work by internationally renowned contributors. The new United Nations Law of the Sea, ratified by over 100 countries within the past two years, provides a framework and guidelines for deep-sea mineral exploration that increases international interest in this book. The Handbook serves as a platform from which to launch the more detailed evaluation studies that will need to take place in the 21st century before recovery can continue or commence. Handbook of Marine Mineral Deposits is useful to mineralogists, economic geologists, marine geologists, marine miners, and conservationists. Features
