Three minerals that are common are feldspars which can be pinkish grey in colour, quartz which can be grey or white in colour, and It also contains small specs of mafic minerals which are dark. It contains crystals, which are interlocking. Mirco granite are pinkish in colour, but can also be grey at times. Ercall Granophyre is a unconformably overlain by Lower Cambrian sandstones. Micro granite forms in an area with magma and quartz rock.…

Black grains of biotite and white grains of plagioclase are dominant in the hand sample. We also see signs of myrmekite forming within this facies. Since this facies consists of considerably smaller grains than the surrounding units it is safe to assume the magma that formed this facies rose to the surface at a faster pace which did not allow the crystals to grow as large as the rest of the…
When I was growing up chicken nuggets were never something that were homemade. They came in brightly colored boxes next to the toy in a fast food meal or were frozen processed morsels served in the school cafeteria. Nevertheless, I loved them. I loved that they were something you could eat with your fingers and I loved the little buckets of sweet and sour sauce that were just the right size for dipping.…

Adakite always contains an abundance of plagioclase. With the exception of high magnesium adakite, amphibole is also a common component. Clinopyroxene, othopyroxene, biotite, and opaques may also be present, but ultimately plagioclase and amphiboles compose the primary adakite mineral assemblage, (Defant and Drummond,…
Its importance to narromine is that a lot of family generations has been to war and we still want to remember them The Inscription: Their memory lives within our hearts, their worth the whole world knows. The Narromine returned soldiers gratefully acknowledge the gift of this fence from T. E. Perry ESA. Eastern side plaque.…
you can find rose quartz in Madagascar, India, japan, Brazil, south Africa, and USA. It is usually found in massive forms. Igneous ,sedimentary,metamorphic quartz is most known mineral on earth. Rose quartz is opaque to translucent macro crystalline. It normally occurs in the cores of large pegmatites as solid masses of rose colored quartz crystals have poorly formed boundaries.…
Mineral that are in flatbread are iron, zinc, calcium and iodine. Iron is mostly added in to wheat flour in countries where there is a high occurrence of iron deficiency and where flatbread is eaten the most. One of those places is the Middle East where there was a high prevalence of people who were deficient of iron. Zinc is also another mineral that was deficient among people and to decrease the occurrence of zinc deficiency, the mineral was added to the flour used to make flatbread. However, adding zinc to the flour reported that the color of the flour changed when it was put in.…
Tungsten is considered a strategic mineral because it is used in many ways. Tungsten has a high heat resistance; therefore, it has applications in things such as filaments in light bulbs, heating elements of heaters and furnaces, and if combined to make an alloy, it can be used in aircraft engines. It also is used often in artistic ways, like in pottery, particularly for a yellow tint, and can be substituted for gold and platinum in jewelry, wedding bands for example, because it is hypoallergenic and has a hardness of 7.5-8, so it is scratch-resistant. It also has a very high density, comparable to gold, as well as the highest melting point of any pure metal. Tungsten is mainly found in the wolfram group which includes ferberite, wolframite…
1991). The Homestake formation is an iron and magnesium rich carbonate (Rye, Doe, and Delevaux 1974). The magnesium rich mineral is sideroplesite (magnesium sericite) (Norton 1971). There is also grunerite and cummingtonite found in the Homestake Formation (Morelli et al. 2010).…
The Blue topaz is found in the enormous crystals in pegmatite dikes (Topaz). Pegmatite dikes comprise extremely coarse crystalline granitic rocks (Dike ( Geology )). It can also be found in rhyolite, gneisses, and schists which are very acidic (Topaz). " Topaz crystallizes from fluorine-rich vapor in the final stages of solidification of igneous rock" (Topaz). Topaz can also be found in…
While, the tricalcium phosphates (TCP) have two different crystalline (Ca3(PO4 )2) known as ambient condition. The hydroxyapatite, HA (Ca10(PO4)6(OH)2) is stable, dense and most insoluble of the CaPs (Boanini et…
When shopping for jewelry, you have probably experienced the overwhelming excitement of searching for that Special Gem; the one specifically made for you. With an infinite combination of gems from diamonds to jadeite and everything in between, how do you recognize whether to pick a diamond from a colored gem? Usually you walk in with several ideas, while trying to leave without having buyer’s remorse. It can be like walking into a fancy restaurant unable to decide between Lobster and Steak. The key to this tricky conundrum is research; figuring out how to determine the ideal gem for you.…
Introduction Brahmaputra River, the peculiar drainage pattern of large Southeast Asian rivers, reflects a complicated tectonic history of crustal deformation in the Himalaya and river re-organization. In general, the Himalayas are divided into three tectono-lithologic domains: the Lower Himalayas, the Higher Himalayas and the Tethys Himalayas (Amano and Taira, 1992); surprisingly this river flows through over these three domains (Fig.1). The mineral assemblages are correlated with these subdivisions of the Himalayas on the basis of the similarity between the inferred geology from mineral assemblages and each provenance-geology. The diversity of detrital mineral assemblages is particularly prominent in modern and ancient siliciclastic sequences of river sediments. The value of the technique lies not only in the number of possible minerals, but also in that many of them have petrogenetic parageneses that positively identify the involvement of particular parent rocks.…
