• Mining basalt

    Basalt rocks do not always deplete when ore is mined and respawn quickly. With a rune pickaxe and less than 80 Mining, 650–850 per hour can be mined. Attention required is comparable to the upper floor of the Motherlode Mine . The crystal pickaxe 's effect does not work on basalt, neither does the prospector kit, celestial ring and derivatives.

  • Basalt: Igneous Rock

    Basalt is a darkcolored, finegrained, igneous rock composed mainly of plagioclase and pyroxene minerals. It most commonly forms as an extrusive rock, such as a lava flow, but can also form in small intrusive bodies, such as an igneous dike or a thin sill. It has a composition similar to gabbro.
