GEOCHEMICAL EXPLORATION OF MINERAL DEPOSITS
3.1 INTRODUCTION. In order to explore the mineral deposits of any country whether exposed or concealed, the basic approach is to prepare the systematic geological map of the concerned area, followed by geochemical and geophysical surveys of the area. In modern times, the geochemical and geophysical surveys have become The Central Kentucky Mineral District, commonly known as the Central Kentucky Fluorspar District, covers part or all of the 16 counties in the Bluegrass Region of central Kentucky and consists of more than 200 vertically dipping vein deposits. Barite, fluorite, calcite, galena, and sphalerite have been sporadically mined in this district sinceCentral Kentucky Mineral District University of Kentucky

Locations of Deposits Massachusetts Institute of Technology
Deposits are typically found in shales, cherts, limestone, dolomites and sandstone as well as hydrothermal veins or as chemically dissolved phosphate minerals in igneous and metamorphic rocks. One of the world's largest phosphate deposit is the Phosphoria Formation, located in southeast Idaho.2 天之前Download scientific diagram Outline geology of Botswana, showing the study area and main mineral deposits in the eastern parts of the country (modified after Williams et al., 1999).

ProMine Data Products EGDI
The efficiency of the overall production chain of minerals and metals in Europe should be enhanced by putting higher quality and added value products on the market. This was addressed by the four year long project ProMine starting on May 2009.

Geology and mineral potential of Ethiopia: a note on
The Precambrian crystalline basement of Ethiopia is of particular interest because of the fact that it contains almost all known mineral commodities of the country (both metallic and industrial minerals and rocks), notably gold, platinum, rare metals, nickel, copper, iron, chromium, kaolin, feldspar, clay, asbestos, talc, etc. Marble, limestoneGeological mapping revealed that the marble deposit stretches in a NE-SW direction, from Muro in the north to Kolo in the south, covering about 28 km 2.

Comparative analysis of mineral mapping for hyperspectral
The traditional approaches of mineral-mapping are time consuming and expensive process. Remote sensing is a tool to map the minerals precisely using their physical, chemical and optical properties. In the present study, Tirunelveli district in Tamil Nadu is selected to extract the abundant mineral such as Limestone using Hyperion and Limestone is an important economic rock.

Hydrothermal Mineral Deposits SpringerLink
Consequently, mineral deposits thus formed have been referred to as late magmatic hydrothermal deposits (Guilbert and Park 1986 ). Hydrothermal processes can proceed over a wide range in temperature from some 700 down to 50 °C (Evans 1993 ). In cases, hydrothermal veins contain banded mineral aggregates displaying spherical, It is extracted from water-filled pits or cut-bank deposits throughout the state. Crushed rock refers to angular limestone and dolostone rock that is blasted (shot) from quarries and fragmented by mechanical crushing; it is quarried throughout the state in Mississippian-, Devonian-, and Silurian-age bedrock.IGWS Indiana Geological and Water Survey
