The physical properties of basalt reflect its relatively low silica content and typically high iron and magnesium content. The average density of basalt is
2.9 g/cm
3
, compared with a typical density for granite of 2.7 g/cm

.
What is the average density of rock?
Most of the rocks comprising the crust of the earth have density
between 2.6 and 2.7g/cc
.
What is the density of basalt sample?
Both of the high-Ti basalts had somewhat higher grain densities (3.42 and 3.46 g cm-3) than the low-Ti basalts
(ranging 3.31 to 3.39 g cm-3)
. Among the low-Ti basalts, the grain den- sities are correlated with the abundance of Al2O3 and of MgO in a manner similar to that observed among lunar meteorite basalts [3].
What is the density of the basaltic oceanic crust?
The average density of oceanic crust is
3.0 g/cm3
, while continental crust has an average of 2.7 g/cm3.
Which rock has highest density?
| Material Density Range (g/cm ) | Igneous Rocks 2.35 -3.50 | Metamorphic Rocks 2.52- 3.54 | Ore-Bearing Rocks 2.30- 7.60 |
|---|
What is the hardness of basalt?
The rock hardness of basalt is
6
as per the Mohs scale and can be observed through a combination of its compressive strength. Generally, 100-300 Mpa or Megapascal is the compressive strength.
Does basalt have a high or low density?
The physical properties of basalt reflect its relatively
low silica
content and typically high iron and magnesium content. The average density of basalt is 2.9 g/cm
3
, compared with a typical density for granite of 2.7 g/cm
3
.
What mineral has the highest density?
Iridium
, at a calculated density of 22.65 grams per cubic centimeter, is probably the densest element known to man. Although osmium, at 22.61 g/cubic cm, is close enough to make the distinction difficult. Most people think lead is the most dense!
Is Clay more dense than sand?
Sandy soils have relatively
high bulk
density since total pore space in sands is less than that of silt or clay soils.
What’s heavier rocks or sand?
| Soil Type Density/g/cm3 | sand 1.52 | sandy loam 1.44 | loam 1.36 | silt loam 1.28 |
|---|
Which type of crust is usually the oldest?
Cratons
are the oldest and most stable part of the continental lithosphere. These parts of the continental crust are usually found deep in the interior of most continents.
Which crust is thicker?
Earth’s crust is generally divided into older,
thicker continental crust
and younger, denser oceanic crust. The dynamic geology of Earth’s crust is informed by plate tectonics.
Which crust is more dense?
Oceanic Crust
is denser that continental crust. Bassically the Oceanic crust is made with volcanic rocks and intrussions from the Mantle (which is more dense than the crust) and it has densities of about 2.9 grams/cubic centimeter.
What rock has the lowest density?
Sedimentary rocks
(and granite), which are rich in quartz and feldspar, tend to be less dense than volcanic rocks.
Does andesite have high density?
How high is your measured density? … Andesites with it’s normal mineralogy generally have densities
between 2.6 to 2.8
. The higher density measured may imply presence of some accessory mineral having higher specific gravity or it could be due to higher concentration of any specific accessory.
Which igneous rocks has highest density?
| Rock Type Density Range (g/cm ) | Igneous Rocks | Rhyolite 2.35 – 2.70 | Granite 2.50 – 2.81 | Andesite 2.40 – 2.80 |
