Hartzburgite is a type of peridotite, which is a dense, ultramafic rock. The density of harzburgite varies depending on its composition and mineral content.

Typical density range for harzburgite:

* 3.2 - 3.4 g/cm³

Factors influencing density:

* Mineral composition: Harzburgite is primarily composed of olivine and orthopyroxene. The relative proportions of these minerals can affect density.

* Porosity: The presence of pores or voids within the rock can reduce its density.

* Pressure and temperature: Density can increase with increasing pressure and temperature.

Note: The density values provided are approximate and may vary depending on the specific harzburgite sample.
