  • Diabase Rock History Origin

    Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar. Diabase is available in dark grey to black colors. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Diabase is black. Get to know more about Diabase rock and characteristics of Diabase rock in the next sections.

  • Rock properties - oocities.org

    Fine-grained and lower porosity igneous rocks, such as basalt and diabase (dolerite) are generally higher in rock hardness than that of coarser grained igneous rocks, such as granite, diorite, and gabbro. As a result, the mineral grains of fine-grained igneous rocks are more tightly held together than that of coarse-grained igneous rocks. In metamorphic rocks, where strong foliations have ...

  • Diabase - Igneous Rocks

    Diabase is composed of plagioclase feldspar (mostly labradorite) and pyroxene . The crystals that make up dolerite are usually visible to the naked eye, but sometimes porphyritic rocks of basaltic composition with pyroxene and especially plagioclase phenocrysts are also named that way.
