  • Glossary Glossary

    Glossary Glossary

    Glossary Glossary Albedo A measure of an object’s reflectivity. A pure white reflecting surface has an albedo of 1.0 (100%). A pitch-black, nonreflecting surface has an albedo of 0.0. The Moon is a fairly dark object with a combined albedo of 0.07 (reflecting 7% of the sunlight that falls upon it). The albedo range of the lunar maria is between 0.05 and 0.08. The brighter highlands have an albedo range from 0.09 to 0.15. Anorthosite Rocks rich in the mineral feldspar, making up much of the Moon’s bright highland regions. Aperture The diameter of a telescope’s objective lens or primary mirror. Apogee The point in the Moon’s orbit where it is furthest from the Earth. At apogee, the Moon can reach a maximum distance of 406,700 km from the Earth. Apollo The manned lunar program of the United States. Between July 1969 and December 1972, six Apollo missions landed on the Moon, allowing a total of 12 astronauts to explore its surface. Asteroid A minor planet. A large solid body of rock in orbit around the Sun. Banded crater A crater that displays dusky linear tracts on its inner walls and/or floor. 250 Basalt A dark, fine-grained volcanic rock, low in silicon, with a low viscosity. Basaltic material fills many of the Moon’s major basins, especially on the near side. Glossary Basin A very large circular impact structure (usually comprising multiple concentric rings) that usually displays some degree of flooding with lava. The largest and most conspicuous lava- flooded basins on the Moon are found on the near side, and most are filled to their outer edges with mare basalts.

    ANALYSIS OF THE DEPTH-DIAMETER RELATIONSHIP OF MARTIAN CRATERS A Capstone Experience Thesis Presented by Jared Howenstine Completion Date: May 2006 Approved By: Professor M. Darby Dyar, Astronomy Professor Christopher Condit, Geology Professor Judith Young, Astronomy Abstract Title: Analysis of the Depth-Diameter Relationship of Martian Craters Author: Jared Howenstine, Astronomy Approved By: Judith Young, Astronomy Approved By: M. Darby Dyar, Astronomy Approved By: Christopher Condit, Geology CE Type: Departmental Honors Project Using a gridded version of maritan topography with the computer program Gridview, this project studied the depth-diameter relationship of martian impact craters. The work encompasses 361 profiles of impacts with diameters larger than 15 kilometers and is a continuation of work that was started at the Lunar and Planetary Institute in Houston, Texas under the guidance of Dr. Walter S. Keifer. Using the most ‘pristine,’ or deepest craters in the data a depth-diameter relationship was determined: d = 0.610D 0.327 , where d is the depth of the crater and D is the diameter of the crater, both in kilometers. This relationship can then be used to estimate the theoretical depth of any impact radius, and therefore can be used to estimate the pristine shape of the crater. With a depth-diameter ratio for a particular crater, the measured depth can then be compared to this theoretical value and an estimate of the amount of material within the crater, or fill, can then be calculated. The data includes 140 named impact craters, 3 basins, and 218 other impacts. The named data encompasses all named impact structures of greater than 100 kilometers in diameter.

    Volcanic Landforms: the Landform Which Is Formed from the Material Thrown out to the Surface During Volcanic Activity Is Called Extrusive Landform

    Download Testbook App Volcanic Geography NCERT Notes Landforms For UPSC ABOUT VOLCANIC LANDFORM: Volcanic landform is categorised into two types they are:extrusive and intrusive landforms. This division is done based on whether magma cools within the crust or above the crust. By the cooling process of magma different types of rock are formed. Like: Plutonic rock, it is a rock which is magma within the crust whereas Igneous rock is formed by the cooling of lava above the surface. Along with that “igneous rock” term is also used to refer to all rocks of volcanic origin. Extrusive Volcanic Landforms: The landform which is formed from the material thrown out to the surface during volcanic activity is called extrusive landform. The materials which are thrown out during volcanic activity are: lava flows, pyroclastic debris, volcanic bombs, ash, dust and gases such as nitrogen compounds, sulphur compounds and minor amounts of chlorine, hydrogen and argon. Conical Vent and Fissure Vent: Conical Vent: It is a narrow cylindrical vent through which magma flows out violently. Such vents are commonly seen in andesitic volcanism. Fissure vent: Such vent is a narrow, linear through which lava erupts with any kind of explosive events. Such vents are usually seen in basaltic volcanism. Mid-Ocean Ridges: The volcanoes which are found in oceanic areas are called mid-ocean ridges. In them there is a system of mid-ocean ridges stretching for over 70000 km all through the ocean basins. And the central part of such a ridge usually gets frequent eruptions. Composite Type Volcanic Landforms: Such volcanic landforms are also called stratovolcanoes.

    Magma Emplacement and Deformation in Rhyolitic Dykes: Insight Into Magmatic Outgassing

    MAGMA EMPLACEMENT AND DEFORMATION IN RHYOLITIC DYKES: INSIGHT INTO MAGMATIC OUTGASSING Presented for the degree of Ph.D. by Ellen Marie McGowan MGeol (The University of Leicester, 2011) Initial submission January 2016 Final submission September 2016 Lancaster Environment Centre, Lancaster University Declaration I, Ellen Marie McGowan, hereby declare that the content of this thesis is the result of my own work, and that no part of the work has been submitted in substantially the same form for the award of a higher degree elsewhere. This thesis is dedicated to Nan-Nar, who sadly passed away in 2015. Nan, you taught our family the importance and meaning of love, we love you. Abstract Exposed rhyolitic dykes at eroded volcanoes arguably provide in situ records of conduit processes during rhyolitic eruptions, thus bridging the gap between surface and sub-surface processes. This study involved micro- to macro-scale analysis of the textures and water content within shallow (emplacement depths <500 m) rhyolitic dykes at two Icelandic central volcanoes. It is demonstrated that dyke propagation commenced with the intrusion of gas- charged currents that were laden with particles, and that the distribution of intruded particles and degree of magmatic overpressure required for dyke propagation were governed by the country rock permeability and strength, with pre-existing fractures playing a pivotal governing role. During this stage of dyke evolution significant amounts of exsolved gas may have escaped. Furthermore, during later magma emplacement within the dyke interiors, particles that were intruded and deposited during the initial phase were sometimes preserved at the dyke margins, forming dyke- marginal external tuffisite veins, which would have been capable of facilitating persistent outgassing during dyke growth.
