As two rocks are not same, it’s fun to compare them. These rocks are composed of many distinct minerals. It is compositionally equivalent to gabbro and basalt but texturally between them. Basalt forms when lava reaches the Earth's surface near an active volcano. Geologists consider traprock to be any dark-colored, fine-grained, nongranitic, hypabyssal or extrusive igneous rock, such as basalt, peridotite, diabase or fine-grained gabbro. Diabase is a common rock type. Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt. It occurs mostly in shallow intrusions (dikes and sills) of basaltic composition. The smaller degree of scatter in the diabase clasts relative to the basalt clasts could be because of a smaller sample set, or a smaller range of LOI variation, or it could be interpreted to suggest that the texturally similar diabase clasts started with a more similar major element composition and perhaps from a common source. Properties of rock is another aspect for Basalt vs Diabase. So, the crushing process of basalt or diabase should be reasonable, taking the investment cost of crushing project and production cost of diabase or basalt mining crushing plant into account at the same time. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Fine grained rocks, and basalts in our case, can also form in hypabyssal settings (underground, for example dykes) if conditions are favourable for very quick nucleation. The finer the grains, the sharper these edges can be-- with the most extreme being obsidian (volcanic glass), which can form from either basaltic or rhyolitic lavas. About us. The basalt rock wool board uses basalt or diabase as a raw material, there is no sulfur source, so no corrosion will occur. Diabase is a synonym of dolerite. "Trap rock" is not a geological term that you are likely to learn about in a geology course or read about in a geology textbook. Because extrusive rocks make contact with the atmosphere they cool quickly, so the minerals do not have time to form large crystals. Here you can know more about Basalt and Diabase.
