  • Golden Geologic History Report: The Journey To Red Rocks Park

    GOLDEN GEOLOGIC HISTORY REPORT It all started with the Big Bang then the whole universe is formed, continued with the formation of the Milky Way, where there is a solar system with the planet Earth and then there were this little town called Golden. This is a report that will travel through time telling the stories of the incidents happened in to this town of Golden. During our journey we must note that the whole geological of Golden is tilted and there were mining done here. Let’s start our journey at Red Rocks Park, the Precambrian Basement, around 1.7 billion years ago, when North America is forming along with the formation of the giant continent Columbia. This is proven by the deep marine limestone and the rock is deposited in the subduction zone. In this time, the rock formed there is the Idaho Spring Gneiss, which has a crystallize-size grain with the minerals K-spars, quartz, biotite, hematite, amphibole. Next, we could see a gap of 1.4 billion years because there is an unconformity caused by missing record of the rock during that time. Fast forward to 300 million years ago during the formation of the ancestral Rocky Mountain. Here, the young geologist of mines found an alluvial fan had formed which deposited a red rock called Basil conglomerate. The rock is red due the mineral hematite, the oxidation or rusting or iron. Besides hematite, the minerals found here is biotite and amphibole with grain size no smaller than 1mm but no bigger than 10mm. This place is called…

  • Surface Of The Earth Research Paper

    Earth is composed of many different components such as minerals, and rocks. These components have several different properties and characteristics which are unique to each. In this paper, I will discuss some of the different properties, characteristics, and uses of three different factors, those being gypsum, coal, and nickel. Gypsum Gypsum is derived from the Greek word gypsos which means plaster (Gypsum Meanings, Powers, and History). Gypsum is composed of oxygen, calcium, sulfur, and water…

  • James Hutton: Increased Intellectual Activity In The 18th And Early 19th Century

    During the Scottish Enlightenment, a period of increased intellectual activity in the 18th and early 19th century, individuals tended to explore multiple disciplines of study (Young, 2016). One prominent Scottish Enlightenment figure was James Hutton, living from 1726 to 1797. During his lifetime he was a lawyer, geologist, chemist, physician, farmer, and naturalist. Hutton, along with other prominent Enlightenment figures, Joseph Black and Adam Smith, founded the Oyster Club. This intellectual…

  • The Importance Of Existance Of Lake Malawi

    2.4. Hydrocarbon potential Previous work reveals presence of mature sedimentary sequence was derived from Jurassic to lower cretaceous periods in the north part of Lake Malawi which has hydrocarbon reservoir prospects. Existence of thick sedimentary sequence rock could possibly trap hydrocarbon especially in lower Shire valley, northern of Lake Malawi. Presence of large proportion volcanic clasts interbedded with sedimentary rocks transported by rivers present for extensive alluvial plain…

  • A Short Summary On Onyx

    Onyx: The Practical and Metaphysical Story Onyx is a specific variety of the mineral known as chalcedony. It is a banded mineral, which means that the layering of the rock that formed it has caused “bands” of different colors to appear. Many people mistake onyx for a type of agate, which is another type of chalcedony, but where agate has curved bands onyx has parallel bands instead. Onyx is found in nearly every color, though bands of black and white are the most common. When onyx is banded…

  • Igneous Rock Formation

    For each sample, provide a detailed description, as precise of a rock name as you can, and an interpretation of the (possible) environment of formation. Quaternary: This is an igneous rock known as Tuff pyroclastic, which is a volcano-clastic rick composed mainly of volcanic ash. This conclusion makes sense as the quick cooling would cause the porous structures. This rock possesses sand to mud sized grains; therefore it is fine grained. This rock has interlocking crystals as well as a…

  • Raton Basin Essay

    Overall the Btu/lb of the coal ranges from 12,210 to 15,150 on a dry basis and increases from the northern to the southern parts of the Raton Basin (Flores and Bader, 1999). The coal within the Vermejo Formation ranges from High Volatile bituminous C to low volatile bituminous (Rooper et al., 2006). Coal petrology indicates a vitrinite reflectance values of 0.57 to 1.58 percent reflectance with the maximum values located in the central part of the basin (Johnson and Finn, 2001). Coal ranks of…
