The Rock Identification Key
Diabase forms from a magma that is rich in iron and magnesium, and poor in silica (quartz). The magma is forced into cracks or between layers of rock near the earth's surface. Diabase is from the same kind of magma as basalt, but …

Diabase or Dolerite Properties and Composition | Earth Know
Dolerite, diabase, or formally microgabbro, is a dark-colored, medium-grained subvolcanic rock equivalent to basalt or gabbro in composition.. Subvolcanic or hypabyssal rock is a plutonic rock that forms at shallower depths less than 2 km (1.2 mi) from the Earth's surface.

The continental flood tholeiitic basalt-diabase assemblages are widely distributed in western Guizhou. Because Luodian is located in the eastern margin of magmatic activity, the intensity of magmatic activity is relatively weak, and no basalts are exposed, resulting in large-scale diabase dike intrusion activities.

The ophiolite section is intruded by various late-stage dikes, including gabbroic pegmatite, diabase, basalt, and plagiogranite. The compositions of clinopyroxene and amphibole suggest that gabbroic pegmatite formed from hydrous high-SiO 2 depleted melts, while whole-rock compositions of basaltic and diabase dikes show negative Nb and Ta ...
