Diabase is a rock with the same composition as basalt or gabbro (lots of calcium plagioclase feldspar and dark iron-rich minerals like amphiboles and pyroxenes), but which is intermediate in texture (grain size) between fine-grained basalt and coarse-grained gabbro. It often means the rock crystallized underground, but at a relatively …
Using IET, Quaglio et al. [2] determined Young's modulus of samples from basalt and diabase mines used as aggregates in the construction industry. Their results showed that values of Young's ...
Lower Keweenawan diabase dikes from Marquette-Baraga Counties, and middle Keweenawan Portage Lake Lavas from upper Michigan, can each be subdivided into two chemically distinct groups: a low TiO2-P2O5 group characterized by higher A12O3 content, higher Mg ratio, and lower total Fe and REE abundances than a high TiO2-P2O5 group. …
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).

Basalt vs Diabase. Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth. Diabase is a fine-grained …
Diabase is a rock with the same composition as basalt or gabbro (lots of calcium plagioclase feldspar and dark iron-rich minerals like amphiboles and …
Basalt is a type of volcanic rock that is formed from the solidification of molten lava. It is an igneous rock, meaning it is formed through the cooling and solidification of magma or lava. Basalt is one of the most common rock types on Earth, and it can be found in various locations around the world, both on land and under the ocean floor.
Cubic 1000 cm 3 samples from the og-1 basalt and og-2 diabase were cut from the original blocks and shaped into spheres of 49 ... (collected from shock zone IV, see Table 1). Color scales and field ranges are identical for each sample for ease of comparison. Note that the central peak of both distributions is slightly offset toward …
When we have to compare Diabase vs Granite, the texture, color and appearance plays an important role in determining the type of rock. Diabase is available in dark grey to black colors whereas, Granite is available in black, grey, orange, pink, white colors. Appearance of Diabase is Vesicular and that of Granite is Veined or Pebbled.
Diabase, fine- to medium-grained, dark gray to black intrusive igneous rock. It is extremely hard and tough and is commonly quarried for crushed stone, under the name of trap. ... diabase closely resembles the volcanic rock basalt, but it is somewhat coarser and contains glass. With increase in grain size, diabase may pass into gabbro. About ...

Andrew Alden/Flickr. Basalt is an extrusive or intrusive rock that makes up most of the world's oceanic crust. This specimen erupted from Kilauea volcano in 1960. Basalt is fine grained so the individual …
Diabase is an intrusive igneous rock composed mostly of plagioclase feldspar and pyroxene minerals. The grains in diabase are larger than those in basalt but smaller than those in gabbro. Diabase is used in the construction industry as trap rock or …
comparison. The ophiolite section is intruded by various late-stage dikes, including gab-broic pegmatite, diabase, basalt, and plagio-granite. The compositions of clinopyroxene and amphibole suggest that gabbroic pegma - tite formed from hydrous high-SiO 2 depleted melts, while whole-rock compositions of basaltic and diabase dikes …
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 because it cools more slowly, it develops slightly larger crystals. Compare To: basalt, gabbro, diorite, serpentinite
The strongest rock in the world in compression is Diabase, which can stand up to 350 MPa. Diabase is a kind of fine-grained igneous rock. Close behind diabase in compressive strength come other fine-grained igneous rocks like Diorite, Gabbro, and Basalt. Interestingly, the one non-igneous rock in this super strong group is Quartzite.
In the United States and Canada, the name "diabase" is used for a dark gray to black, fine-grained, intrusive igneous rock that has a composition similar to basalt and gabbro. The …
Comparison of clast spidergrams with the various basalt provinces shows that most basalt clasts exhibit a reasonable match with typical E-MORB or CFB, although the clast from interval 149-899B-27R-1, 19-26 cm plots between E-MORB and N-MORB. All clasts show anomalously high K peaks, and often high Rb, relative to that predicted for unaltered E ...
Fig. 9 shows the comparison of the confusion matrices of different models.

The probabilities of identifying siltstone as anorthosite, phyllite, and ...
Diabase is an intrusive igneous rock with the same mineral composition as basalt. It cools under basaltic volcanoes, like those at mid-ocean ridges. ... Diabase cools moderately quickly when magma moves up into fractures and weak zones below a volcano. There, it forms dikes (tabular igneous rock bodies that cut across pre-existing rock layers ...
