Glossary of Scientific Terms
In an effort for full transparency, we wanted to give you all the facts on the project, many of which are quite technical. Below is a list of terminologies used throughout the site, to give you a better understanding of the project.
GLOSSARY OF TECHNICAL AND SCIENTIFIC TERMS
The iron-aluminum member of the garnet group, characterized by a deep-red color. Fe3 Al2 (SiO4)3
A monomineralic plutonic igneous rock composed almost entirely of plagioclase feldspar. (Na,Ca) [Al (Si,Al) Si2 O8]
Improvement of the grade of ore by various processes, milling, sintering, concentration or value adding to minerals into more useful products.
A low, smoothly rounded, elongate oval hill, mound or ridge of compact glacial till. Its longer axis is parallel to the direction of the movement of the glacier.
A ridgelike accumulation of rocks and debris that is produced at the margin of an actively moving glacier.
Essential mineralogy composed of greater than 50% potash plagioclase feldspars, commonly 45% ferromagnesian minerals iron-rich including hornblende, biotite, pyroxenes, and 5% quartz, apatite, zircon, titanite, magnetite, ilmenite, etc.
The formation by glacial action of smooth deep gutterlike channels on the stoss side of a rocky hill obstructing the advance of a glacier.
Pertains to sedimentary deposits of a river consisting of material transported by, suspended in, or laid down by the flowing water.
An iron-black, opaque, rhombohedral mineral from basic igneous rocks like gabbro, occuring as a common accessory mineral or in mineral sands. FeTiO3
A low mound or short irregular ridge composed of stratified sand & gravel deposited by sub-glacial streams (deposits of glaciofluvial or glaciolacustrine sand).
Basin or bowl shaped depressions, commonly without surface drainage, in glacial-drift deposits.
Pertaining to, produced by or formed in a lake.
Fine grained, opaque, whitish alteration products of ilmenite, commonly consisting of rutile and anatase or sphene and occurring in some igneous rocks.
A black, cubic, strongly magnetic, opaque mineral of the spinel group. Commonly containing titanium oxide and an important ore of iron. ( Fe2+Fe3+ ) [ Fe3+O4 ]
The mineralogical, chemical, and structural adjustment of solid rocks to physical and chemical conditions that have generally been imposed at depth below the surface zones of weathering and cementation, and which differ from the conditions under which the rocks in question originated.
A device for microanalysis that operates by exciting radiation in a minute area of material so that the composition may be determined from the emission spectrum.
A standard of 10 minerals by which the hardness of a mineral may be rated. The scale includes, from softest to hardest and numbered one to ten: gypsum; calcite; fluorite; apatite; orthoclase; quartz; topaz; corundum and diamond.
An accumulation of boulders, stones, or other debris carried and deposited by a glacier.
An elongated ridge or row of lateral and terminal moraines, sometimes forming an amphitheatrical arrangement often by valley or outlet glaciers.
A glacier issuing from an ice sheet or ice cap, through a mountain pass or valley, contained to a channel or pass by exposed rock.
A layer of large, durable fragments of broken rock, specially selected and graded, the purpose of which is to prevent erosion by waves or currents on a shoreline.
The removal, extraction, harvesting or scooping of sand from designated sites.
Referring to a once prominent geologic feature that has been altered by chemical or physical mechanisms, such as smearing by the superincumbent weight of glacial ice.
STOSS & LEE TOPOGRAPHY
An arrangement in a strongly glaciated area of small hills having gentle slopes on the stoss side and somewhat steeper slopes on the lee side.
The remaining matter, after all associated value has been processed, from a sandharvesting operation. Tailings are often used for shoreline or land mass reconstruction.
To increase water holding capacity of a lake or stream through the excavation of sands and silts.
