Diabase or Dolerite Diabase or dolerite is a mafic, holocrystalline, subvolcanic rock equivalent to volcanic basalt or plutonic gabbro. Diabase dikes and sills are typically shallow intrusive bodies and often exhibit fine grained to aphanitic chilled margins which may contain tachylite (dark mafic glass). Diabase differ from gabbros chiefly in ...

It's shown that SLM technology can produce test samples prototyping building units for construction use on the Moon from specially prepared powder compositions of gabbro-diabase simulating lunar regolith. Fabricated samples with characteristic dimensions of 5 × 6 × 7 mm 3 have rather high compressive strength of 17–20 MPa with porosity of 33–39 %.
Diabase (), also called dolerite or microgabbro, is a mafic, holocrystalline, subvolcanic rock equivalent to volcanic basalt or plutonic gabbro. Diabase dikes and sills are typically shallow intrusive bodies and often exhibit fine grained to aphanitic chilled margins which may contain tachylite (dark mafic glass).
Like diabase, gabbro often forms dikes or sills, though it can also be found in massive form. Gabbro can be divided into two different types: fine-grained and coarse-grained gabbro. Fine-grained gabbro has a more even grain size, while coarse-grained gabbro has larger crystals.
Gabbro Diabase is a kind of black gabro quarried in Russian Federation.

Gabbro, diabase, and anorthosites are formed by ∼1–5% melting of the, whereas depleted harzburgites were generated by slightly higher degrees of partial melting (∼10–20%) of the spinel lherzolite source. Trace element modelling reveals the influence of mid-oceanic ridge basalt (MORB)-melt interaction and subduction-related mantle ...
This analysis, based on the modal mineralogy and seismic properties of oceanic diabase and gabbro samples, shows that the H 2 O content of diabase dike rocks ranges from 1–3%, with an average of 1.5%; in oceanic gabbros, the H 2 O content decreases with increasing seismic velocity, and gabbros that have velocities typical of the lower oceanic ...
The Hidaka Series of the Shimokawa mining area consists mainly of an apparent ophiolite suite that comprises ultramafic rocks, gabbro, diabase, massive and pillow basalts, with numerous intercalated pelitic, psammitic and rarely calcareous layers. These rocks are widely altered and the assemblages of replacing min-erals range from prehnite ...
A gabbro-diabase sample of cylindrical shape (L = d) without visible defects was prepared for the studies. The gabbro-diabase sample was characterized by a massive texture and a uniform medium-grained structure. The size of mineral grains was up to 2–3 mm. The experiment included X-ray tomography of the gabbro-diabase sample with
