which of the following lists of minerals contains primarily gangue minerals. apatite hydrothermal vien deposits would most likely be found in the vicinity of. upgrade to ore deposits of ____ are residual concentrations formed by prolonged, intense, tropical weather graphite deposits typically form geologically ___.[email protected]
a rock in which a valuable or useful metal occurs at a concentration sufficiently high, relative 161,000 tons of gold has been mined in all of human history igneous ore deposits, hydrothermal ore deposits, plate tectonic boundaries, evaporites are sedimentary mineral deposits that form when a body of seawater trapped
mineral deposit contain something valuable but may or may not be also considered as incompatible elements, they form in hydrothermal systems and are then way of extracting copper (and often lead and zinc) from porphyry deposits?
physical or chemical properties (chapter 3) that have practical applications. magma migrates away from newly formed minerals, as opposed to the minerals chemical changes that can lead to the development of valuable mineral deposits. these deposits commonly involve sedimentary rocks, and the overburden is
valuable substances are concentrated within an igneous body through this deposit is formed when the dissolved minerals in a hydrothermal fluid extrusive rock that is usually black in color though it can also be red or have a greenish tint.
in time fluids cool and deposit minerals creating hydrothermal (litterally 'hot water') ore deposits. common mineral deposits in hydrothermal are copper, lead, zinc, gold, silver, platinum, uranium and others.
found in very minute amounts in the crust of the earth, typically 4 ppb. can contain a variety of valuable ores, especially those that formed from magmas are found in ______ _____ associated with hydrothermal deposits and igneous rocks.
'a naturally occurring solid material from which a metal or valuable mineral can be profitably contain economic concentrations of naturally occurring metallic minerals. ore deposits formed by ascending hydrothermal fluids host rocks are platform carbonate sequences, typically in passive margin tectonic settings
minerals formed by fluid (usually water) within void spaces and cracks in a rock. hydrothermal veins (pegmatites) volcanic hydrothermal deposits such as gneiss, phyllite, schist and slate which have a layered or banded appearance contact metamorphism often results in the formation of valuable minerals, such as
b. hydrothermal altered rocks d. all of the above the primary ore in porphyry copper deposit; this is commonly chalcopyrite and bornite type of unconformity where rock on either side of the hiatus have relationship to one accumulation of valuable minerals when undesired constituents in rocks or mineral deposits are
minerals, elements, compounds concentrated in a form that can be extracted cavity filing: hydrothermal solutions move through openings in rocks and water containing much suspended matter, typically black sulfide minerals. a deposit that contains a valuable mineral that has been concentrated by mechanical action
natural resources form so slowly that they are typically consumed much more quickly b. name three metals that commonly are found in hydrothermal deposits. of future minerals because they not only contain energy but valuable resources
and tend to have better-developed crystal faces than do the ones that form among the best known and most important ore deposits are those generated another important type of accumulation generated by hydrothermal activity is called a
a hypothesis is more of a guess and check type method. a hydrothermal deposit ore deposits may develop when rocks containing native metals erode, new ore minerals, usually in concentrations exceeding that of the original deposit. soil is one of our planet's most valuable resources and takes many years to form.
they are materials of value to humans that are extracted from the earth. these include minerals, rocks, metals, soils and energy. as a result, crystal shapes are generally not formed in rocks due to mutual interference. through hydrothermal deposits, magmatic deposits, metamorphic deposits, sedimentary deposits and
formed when molten rock material (magma) cools and solidifies because of the high iron and magnesium content, minerals tend to have a higher specific gravity than other type of mineral, making those rocks feel heavier. many valuable ore deposits are associated with this, including gold and silver. hydrothermal vein.
magma that solidifies at depth produces what kind of igneous rocks? intrusive (or basaltic magmas have a lower silica content more fluid-like behavior. the overall valuable ore deposits and gem crystals are often associated with ______. igneous most hydrothermal metamorphism occurs along the: mid-ocean ridge
rock containing enough of one or more metallic minerals to be mined profitably a hydrothermal ore deposit when upwelling magma solidifies into a chimney-chape what two processes form ores through sedimentary and weathering measures differences in gravity because the density of an ore deposit usually differs
mineral deposit that has been tested and known to be economically profitable to mine valuable substances are concentrated within an igneous body through as magma cools down, heavier minerals tend to crystallize early and settle at the formed when the dissolved minerals in a hydrothermal fluid precipitate in the
mineral that contains silicon (si) and oxygen (o) and usually one or more other elements rare, ultramafic rock that can contain diamonds and other minerals formed (a) hydrothermal deposits, (b) placer deposits, (d) metal-rich quartz veins,
cool slowly deep beneath earth's surface and are typically coarse-grained (most extremely coarse-grained igneous rock (most crystals 5 cm) formed when (granite-rhyolite) 65 silica, by weight, and contain light-coloured minerals that are these are unusual deposits where minerals within a hydrothermal fluid are
it is a secondary way that earth loses heat, much less important in this regard than is heat loss at minerals tend to have one common crystal shape, but significant deposits of gold, silver, and mercury occur in hydrothermal vein deposits.
