Geophysical techniques are helpful in diamond exploration because Kimberlites often have characteristic geophysical signatures that are unique or distinctive when compared to those of the surrounding rocks.* Glacial DriftSediment that is either in transport in glaciers or deposited by glaciers.* GneissA coarseograined rock in which bands rich in granular materials alternate with bands of mainly metamorphic rock.* GraniteA light colored, coarse-grained, igneous rock consisting of quartz, alkali feldspar, micas and other associated minerals.
* GradeIn diamond exploration, the number of carats in a physical unit of ore, usually expressed in carats per ton.* Gravity SurveyMeasurements of the gravitational field at a series of different locations. The object of such a survey is to associate variations with differences in the distribution of densities and hence of rock types.* Heavy MineralA mineral of sedimentary rock, of high specific gravity.* Heavy Liquid SeparationSeparation of ore particles by allowing them to settle through, or float above, a fluid of intermediate density* Host RockA body of rock serving as host for other rocks or for mineral deposits.* HypabyssalA general adjective applied to minor intrusions such as sills and dykes, and to the rocks that compose them. Hypabyssal rocks are those that have risen from the depths as magma but solidified mainly as minor intrusions such as dykes and sills before reaching the surface.* Igneous RocksFormed by solidification of hot mobile material termed magma.* IlmeniteThe principle ore of titanium. A kimberlite indicator mineral.* Indicator Mineral TrainThe area where kimberlite indicator minerals are concentrated is variously described as indicator mineral "train", "fan", "dispersion", or "anomaly". The "train" was created by glacial ice which carried surface material and dispersed over vast areas. Kimberlites are soft and tend to weather more readily than "older" country rocks. As a result, any kimberlite that lay in the path of a glacier was scoured out, incorporated into the glacial drift and dispersed across the landscape. Kimberlite indicator minerals were similarly dispersed through the same process.Did You Know You Could Buy Engagement Ring With 1 Carat Of High Color And Clarity Grade Diamonds At Secret-Diamond.com For Under $2,000?
