dolerite rock mineral composition

dolerite rock mineral composition

As a general rule, non-metallic minerals have low densities while metallic minerals have high densities. Minerals in this rock include olivine, plagioclase feldspar, pyroxene, quartz and sometimes ilmenite, biotite, hornblende and magnetite. Initially, rock breakdown into smaller particles is by physical weathering. L:ca.90cm. Dolerit (griech. Diabase or dolerite or microgabbro is a mafic, holocrystalline, subvolcanic rock equivalent to volcanic basalt or plutonic gabbro. It is a calcium magnesium carbonate with a chemical composition of CaMg(CO3)2. Mineral Densities . Diabase typically has a mineral composition that is dominated by the plagioclase feldspar known as labradorite (approximately 40% to 70% of the rock). Rock powders were fused to make glass disks for XRF analysis, and acid-digested in steel-jacketed Teflon “bombs” to produce solution for ICP–MS analysis. Steinsberg, Laurenburg, Taunus, Rheinl.-Pfalz. Akzessorisch treten daneben noch Apatit, Ilmenit und exogene Einschlüsse auf.

The famous Pniel Kopje was of this age, the depth of sinking,about 30 feet, consisting of a few feet of fine gravel, composedof agates, chalcedony, amygdaloid, dolerite, &c, with some gar-nets, ilmenite, topaz, quartz, and diamonds. Minor amounts of hornblende, olivine, magnetite, and quartz can be found in some diabase rocks. In British and Australian usage: A medium grained mafic intrusive rock whose main components are calcic plagioclase and clinopyroxene and which is characterized by ophitic to subophitic texture; usually found in sills and dykes. Bedrock jointing, veins and rock fabric extend upward from the bedrock into the mealy material but are truncated abruptly at the contact with the clayey subsoil. November 2020 um 11:24 Uhr bearbeitet. The differing crystal sizes are due to the different rate of cooling, basalt cools quickly and has a very fine structure, while gabbro cools very slowly, at great depth, and large crystals develop.

Doleritgänge treten häufig in Gangschwärmen auf, in denen viele, manchmal hunderte von Gängen ungefähr parallel ausgerichtet sind oder radial von einem vulkanischen Zentrum ausgehen. These larger occurrences of dolerite mostly contain pyroxene as the dominant ferromagnesian mineral and are largely the rock called "diabase" by petrographers, while cases where hornblende is dominant are mostly confined to dikes and smaller intrusions, especially in the older rocks. dem plutonischen Gabbro entspricht.

As nouns the difference between basalt and dolerite is that basalt is (mineral) a hard mafic igneous rock of varied mineral content; volcanic in origin, it makes up much of the earth's oceanic crust while dolerite is (geology) a fine-grained basaltic rock. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. It occurs mostly in shallow intrusions (dikes and sills) of basaltic composition. Dolerit besitzt ein porphyrisches bis sperrig-ophitisches oder intersertales Gefüge.
