diabase
A fine-grained igneous rock composed mostly of pyroxene and feldspar
An igneous stone, closely related to granite Diabase is usually used for high accuracy applications
It includes part of what was early called greenstone
- a dark, fine grained igneous rock that generally forms dikes or irregular bodies
A common intrusive rock with a crystal structure intermediate between gabbro and basalt Between Gunflint Lake and Superior (BWCAW Region 5) Keweenawan sills and dikes of diabase intruded up through the older slate, much of which later was eroded away, or scraped away by glaciers, leaving the harder diabase ridges which define the long narrow east/west lakes and valleys so characteristic of this area
{i} igneous rock, basic holocrystalline dark-colored rock (Geology)
medium grained mafic volcanic rock
A basic, dark-colored, holocrystalline, igneous rock, consisting essentially of a triclinic feldspar and pyroxene with magnetic iron; often limited to rocks pretertiary in age
or dolerite Fine-to medium-grained, dark gray to black intrusive igneous rock. Diabase is one of the dark rocks known commercially as "black granite." It is extremely hard and tough and is commonly quarried for crushed stone, under the name "trap." Chemically and mineralogically, diabase closely resembles the volcanic rock basalt, but it is generally somewhat coarser grained
