What is the density of intermediate rocks?

Densities of Igneous Rocks

What is intermediate igneous rocks?

Igneous rocks are classified according to their mineral content: Intermediate rocks are roughly even mixtures of felsic minerals (mainly plagioclase) and mafic minerals (mainly hornblende, pyroxene, and/or biotite). There is little or no quartz.

What are the two intermediate mafic?

Compilations of many rock analyses show that rhyolite and granite are felsic, with an average silica content of about 72 percent; syenite, diorite, and monzonite are intermediate, with an average silica content of 59 percent; gabbro and basalt are mafic, with an average silica content of 48 percent; and peridotite is …

How are intermediate rocks formed?

Intermediate rocks are produced primarily in convergent plate boundaries in which an oceanic plate is subducting beneath either another oceanic plate (such as in Japan) or a continental plate (such as along the Andes Mountains of South America).

What is the density of peridotite?

The serpentinized peridotites show remarkably uniform bulk densities (~2.4 g/cm3) and grain densities (~2.66 g/cm3). Grain densities for the basalts and mass flows range between 2.76 and 3.00 g/cm3, and bulk densities range from 2.3 to 2.8 g/cm3.

What are examples intermediate rocks?

Typical intermediate rocks include andesite, dacite and trachyandesite among volcanic rocks and diorite and granodiorite among plutonic rocks.

What rocks are intermediate?

Can granite be intermediate?

Granodiorite. An intermediate form between granite and diorite.

Which rock has an intermediate composition?

How to calculate the density of limestone ballast?

Type in inches and feet of your project and calculate the estimated amount of Gravel Stone in cubic yards, cubic feet and Tons, that your need for your project. The Density of #4 Limestone Ballast: 2,410 lb/yd³ or 1.21 t/yd³ or 0.8 yd³/t

How big should the particle density of ballast be?

When determined in accordance with AS 1141.6 the particle density of ballast material shall not be less than 2500 kg/m3. 6.4 Dimensional Requirements 6.4.1 Particle Size Distribution

What should be the mass of a crushed rock ballast?

The crushed rock ballast shall have at least 75 % of the particles by mass with two or more fractured faces and at least 98 % of the particles by mass with one fractured face.

What kind of rock is used for ballast?

Limestone or quartz is often most used as ballasting because it is a hard stone that will lock together providing for extra strength.
