May 06, 2007· Best Answer: Both basalt and granite are types of rock, and a rock is composed of multiple minerals - except for some rocks composed of essentially one mineral like limestone (calcite) or quartzite (quartz). Minerals are crystalline compounds with known characteristics such as hardness, specific gravity, etc. Therefore the hardness of the rock depends on the exact location on the rock .
Jan 12, 2013· Is basalt harder than granite? – Yahoo! Answers. May 06, 2007 · Both basalt and granite are types of rock, and a rock is composed of multiple minerals . So the hardness of a rock is determined by the minerals, . »More detailed
The hardness of a mineral relates to its resistance from abrasion, and is defined in terms of Mohs hardness scale. 5 Apatite, 6 Feldspar (some river rock, some type of granite), 7 Quartz (some river rock, some types of granite, basalt, quartz, trap rock), 8 Topaz, 9 Corundum (flint, chert, trap rock, basalt.
Aug 30, 2012· Quartz monzonite, which tends to contain less quartz than granite, is of a hardness - 5.5 to 6 - similar to the low end of the granite Mohs scale. Class of Rock Both granite and quartz monzonite are igneous rocks, which, along with sedimentary and metamorphic types, constitute the major classes of rock.
Mar 14, 2007· well, big is grand, sandstone or granite.... but my personal favorite for the purely asethetic feel and solid smoothness is the basalt of paradise forks (AZ). with only 80 or so fee, it obviously can't compare to the summit experience of an obscure multi, but those straight up vert cracks, solid and smooth gray rock - it's something to experience.

Many types of crushed stone: Crushed stone is not a "standardized commodity." It is made by mining one of several types of rock such as limestone, granite, trap rock, scoria, basalt, dolomite, or sandstone; crushing the rock; and then screening the crushed rock to sizes that are suitable for the intended end use.
Basalt is one of the most common rock types in the world. Basalt is the rock most typical of large igneous provinces. The largest occurrences of basalt are in the ocean floor that is almost completely made up by basalt. Above sea level basalt is common in hotspot islands and around volcanic arcs, specially those on thin crust.
Aug 14, 2011· The key difference between basalt and granite is that basalt is mostly occurring on ocean floors, while granite is in the crust of the earth in all continents. Earth contains three kinds of rocks namely igneous rocks, sedimentary rocks, and metamorphic rocks. Basalt and granite are two types of igneous rocks.
Basalt is available in black, brown, light to dark grey colors. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Basalt is white to grey. Get to know more about Basalt rock and characteristics of Basalt rock in the next sections.
Basalt is commonly very fine grained, and it is nearly impossible to see individual minerals without magnification. Basalt is considered a mafic silicate rock. Among other characteristics, mafic minerals and rocks are generally dark in color and high in specific gravity. This is in large part due to the amount of iron, magnesium, and several ...
Granite is an intrusive rock that is formed when magma cools inside the crust. This slow cooling gives time for crystals to grow, making it more coarsely grained than an extrusive rock. This coarse grain makes granite a favorite of rock climbers. Basalt, on the other hand, has a smooth texture from rapid cooling, usually by water. Granite is a ...

Granodiorite is a plutonic igneous rock, formed by intrusion of silica-rich magma, which cools in batholiths or stocks below the Earth's surface. It is usually only exposed at the surface after uplift and erosion have occurred. Etymology. The name comes from two related rocks to which granodiorite is an intermediate: granite and diorite.

Granite is lighter in color than basalt. The color of the rocks is dependent on the mineral composition of the rock. Basalt is basic and contains a substantial amount of olivine whereas granite is ...
Granite is a medium-tocoarse-grained acid igneous rock with essential quartz (>20%) and feldspar, where alkali feldspar constitutes between 100 and 35% of the feldspars, and minor mafic minerals. Gabbro is a dark, medium- to coarse-grained intrusive igneous rock composed of calcium plagioclase, pyroxene, and minor olivine, but no quartz.
Basalt is a major rock type that occurs in virtually every tectonic setting. Basalt is clearly the most common volcanic rock on Earth and basaltic rocks (including gabbro, diabase and their metamorphosed equivalents) are the most common rocks in the crust 2.Basalt is also common on the Moon and other rocky planets of the Solar System.
