Fig. 4 shows the variation of RQD with the length of sampling line L for discontinuity frequency λ = 10 m −1 and length threshold t = 0.1 m. It can be seen that when L is smaller than about 0.5 m, RQD increases significantly as L increases. When L is larger than 0.5 m, RQD changes slightly with L.Therefore, it is important to use sampling lines …

Basalt Rock Properties and Uses

Basalt is a finely granulated igneous rock, which is usually black or gray in color. Most basalt rocks are primarily composed of the minerals pyroxene and feldspar. These rocks are formed due to lava flow. It is a type of rock that is abundantly found in the crust of the Earth, and although now found very commonly on land, most ocean floor ...

Basalt Rock

Basalt is an extrusive igneous or volcanic rock that has a low silica content, dark in colour, and is very rich in iron and magnesium. Basalt rock is mainly composed of pyroxene, olivine, and plagioclase and is the most common rock on the earth's surface. The texture of basalt rocks is coarsely porous as those holes are left by gas bubbles.
