Properties of Dolerite
Dolerite is a type of fine-grained, dark-colored igneous rock that is often medium to coarse-grained. It’s commonly formed below the Earth’s surface from the cooling of molten magma. Dolerite is primarily composed of minerals such as plagioclase feldspar, pyroxene, and sometimes olivine.
The following table provides a list of dolerite properties in both SI and US customary/Imperial units at normal temperature and pressure (NTP).

| Physical Properties | Metric |
|---|---|
| Density | 2700 - 3000 kg/m3 |
| Porosity | 1 - 2% |
| Mechanical Properties | Metric |
| Young’s Modulus (E) | 53 - 77 GPa |
| Tensile Strength | 15 - 35 MPa |
| Compressive Strength | 151 - 185 MPa |
Unless stated otherwise, all values are taken at room temperature (approximately 20°C or 68°F) and 1 atm pressure. (1 atm = 101,325 Pa)
