diabase, also called Dolerite, 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. Although not popular, it makes an excellent monumental stone and is one of the dark-coloured rocks commercially known as black granite.

Definition – Trap Rock, also known as either trapp or trap, is a name used in the construction industry for any dark-colored igneous rock that is used to produce crushed stone.Basalt, gabbro, diabase, and peridotite are the most common rock types referred to as trap rock. Trap Rock is a form of igneous rock that tends to form polygonal vertical fractures, most typically hexagonal, …

Crushed basalt is used for road base, concrete aggregate, asphalt pavement aggregate, railroad ballast, filter stone in drain fields. But, basalt is also cut into dimension stone. ... Basalt is identical to diabase and gabbro, but is very fine-grained. Basalt is from a melt that cooled very rapidly- in other words, on the surface of the earth ...
The Basalt crushing production line is divided into three stages: coarse crushing, medium fine crushing and screening. The first stage: coarse crushing The diabase stone blasted from the mountain is fed uniformly by the vibrating feeder through the silo and transported to the jaw crusher for coarse crushing.
More generally, basalt and diabase are hard and tough materials. Basalt and diabase have higher hardness and silicon content, which belong to materials that are hard to crush in actual crushing operations or have higher crushing costs. More generally, basalt and diabase are hard and tough materials. Search Home Products Solutions Blog
After processing, the crushed stone is subjected to sieving processes to obtain crushed stone in different sizes (Table 3). Extraction of crushed stone can be made from several rocks according to local geological characteristics such as: granite rocks, basaltic rocks (basalt and diabase), limestone (limestone and dolomite) and a small part of quartzite and gravel (Engidasew and …
Diabase and gabbro have the same general mineral composition as basalt, but they have a larger grain size. Basalt is identical to diabase and gabbro, but is very fine-grained. Basalt is from a melt that cooled very rapidly- in other words, on the surface of the earth or in the ocean. When basalt is broken, it leaves very sharp edges.
Today, basalt is commonly used as crushed aggregate in construction projects. Crushed basalt is used for road base, concrete aggregate, asphalt pavement aggregate, railroad ballast, filter stone in drain fields. But, basalt is also cut into dimension stone. In thin slabs it is used for building veneers, flooring, etc. Does basalt absorb water?
Trap rock, i.e. basalt or diabase, has a variety of uses. A major use for basalt is crushed rock for road and housing construction in concrete, macadam, and paving stones.
River aggregate is used as a benchmark, and from crushed aggregates: limestone, andesite, diabase and basalt. The drawn conclusion is that fine crushed aggregate has an important influence on concrete consistency because it decreases concrete's workability and placing. Replacement with river aggregate improves concrete consistency.
Uses. Trap rock, i.e. basalt or diabase, has a variety of uses. A major use for basalt is crushed rock for road and housing construction in concrete, macadam, and paving stones.Because of its insensitivity to chemical influences, resistance to mechanical stress, high dry relative density, frost resistance, and sea water resistance, trap rock is used as ballast for railroad track bed and ...
Diabase and basalt are extensively quarried for crushed stone, aggregate, road metal, fill, subbase^and rip-rap. The materials commonly meet State Highway specifications because of their uniform texture and toughness; they are readily quarried because of an intersecting network of closely to moderately spaced joints that
The purpose of this field stop is to visit the Pennington Trap Rock quarry where crushed stone products of Jurassic diabase are quarried, processed, and sold.
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.
The Basalt crushing production line is divided into three stages: coarse crushing, medium fine crushing and screening. The first stage: coarse crushing. The diabase stone blasted from the mountain is fed uniformly by the vibrating feeder through the silo and transported to the jaw crusher for coarse crushing. The second stage: medium and fine ...
3/4" Minus Crushed Basalt is our most commonly used driveway gravel. It is a locally crushed basalt from 3/4" all the way down to 0", so it contains the fines from the crushing process. It is these fines that will help the rock to pack in and stay in place while driving on it.

Diabase is actually a variety of gabbro which consists mainly of labradorite feldspar, augite, magnetite, and olivine. The grain size of diabase is on the smaller side. Diabase and gabbro have the same general mineral composition as basalt, but they have a larger grain size. Basalt is identical to diabase and gabbro, but is very fine-grained.
