The basaltic radical of the oceanic late is divide as(1) felsic, v a density of 2.7 g/cm3 (2) felsic, v a thickness of 3.0 g/cm3 (3) mafic, v a thickness of 2.7 g/cm3 (4) mafic, through a density of 3.0 g/cm3


You are watching: Which property is most useful in distinguishing pyroxene from amphibole

Which home is most beneficial in differentiating pyroxene indigenous amphibole?(1) sample dimension (3) form of luster(2) hardness (4) angle of cleavage
Dolostone is classified as which form of rock?(1) land-derived sedimentary rock(2) chemically developed sedimentary absent (3) foliated metamorphic rock(4) nonfoliated metamorphic rock
Which mineral has actually a metallic luster, a black streak, and also is one ore the iron?(1) galena (2) magnetite(3) pyroxene (4) graphite
Which rock is sedimentary in origin and also formed as a an outcome of chemical processes?(1) granite (3) breccia (2) shale (4) dolostone
Which igneous rock has actually a vesicular texture and contains the minerals potassium feldspar and quartz?(1) andesite (2) pegmatite (3) pumice (4) scoria
Quartz and halite have various crystal shapes generally because(1) light shows from crystal surfaces(2) power is released throughout crystallization(3) that impurities that create surface variations (4) of the internal setup of the atoms
Which 2 minerals have actually cleavage plane at ideal angles?(1) biotite mica and muscovite mica (2) sulfur and amphibole(3) quartz and calcite(4) halite and pyroxene
Wavy bands of light and dark minerals clearly shows in gneiss radical probably created from the(1) cementing together of individual mineral seed (2) cooling and also crystallization of magma(3) evaporation of an ancient ocean(4) heat and pressure throughout metamorphism
A college student obtains a cup the quartz sand from a beach. A saltwater systems is poured into the sand and enabled to evaporate. The mineral residue from the saltwater solution cements the sand seed together, developing a product that is most comparable in beginning to(1) one extrusive igneous absent (2) one intrusive igneous rock (3) a clastic sedimentary rock (4) a foliated metamorphic rock
