Basalt is a hard, durable rock with a high compressive strength of 266±98 MPa and resists chemicals and acids. Also, it is safe and not carcinogenic, i.e., it doesn't cause cancer and is a poor conductor of heat. These excellent properties make it a number one choice of rock for many constructions, industrial, and other uses.
Basalt has a number of unique properties that make it useful for various applications. For example, it is known for its durability, strength, and resistance to wear and erosion, making it ideal for construction materials such as road aggregates, concrete, and building stones.Basalt is also used for manufacturing fiber reinforcement materials, known as basalt …
Chemical compositions of the original volcanic rocks (i.e., fresh country rock, alkaline basalt) distributed in the LH, LX magnetite deposits and HT, FM pyrite deposits are listed in Table 2, and the chemical compositions of altered rocks in those deposits are listed in Table 3 (Zhang, 1979, Zhang, 1980, Zhang et al., 2002, Zhang et al., 2010).

The raw material of the bolt is basalt rock, which is widely distributed in the world (Fig. 1(a)). The basalt rock is crushed and added to the melting furnace; when the temperature increases to 1450–1500 °C, the basalt rock is converted to liquid magma.
Basalt, a volcanic rock born from the cooling of lava, holds a crucial place in the geological heritage of Ireland. This captivating country boasts one of the most diverse and abundant collections of basalt sites and …
As a type of basic volcanic rock, basalt is widely distributed across the Earth's surface, spreading on the ocean floor and continents. Continental basalt accounts for approximately 5.2% of the continental crust area (Suchet et al., 2003). Basalt contains significantly higher concentrations of heavy metals such as Cr and Ni when compared to ...

The evolution of faults and paleodrainage patterns on the southwestern Australian passive margin during and after the breakup of Gondwana in the Early Cretaceous remains poorly understood.
The Baihetan hydropower station is located at the downstream of Jinsha River which is between the regions of Qiaojia Country in Yunnan Province and Ningnan Country in Sichuan Province, Republic of China (Espada et al., 2018; Fan et al., 2018; Feng et al., 2016; Zhao et al., 2018). ... the internal implicit joints are widely distributed in ...
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. Basalt is known for …
The study area: Volcanic activity that accompanied the opening of the Red Sea from the Miocene (25 Ma) to the present, resulted in the formation of vast fields of subaerial basaltic flows in the western part of Saudi Arabia, referred to by the Arabic term 'Harrat'. These harrats cover an area over about 90,000 km 2 and extending over parts of the Proterozoic …
The global distribution map of basalt samples is shown in Figure 4. Each basalt sample was assigned with 11 major elements (SiO2, Figure 4. Global distribution map of basalt sample collection ...
There exists a considerable body of literature on subsurface basalt deposits within central igneous provinces, and many researchers (McGrail et al. 2006), (Pollyea et al. 2014) and (Matter et...
The ages revealed that (1) the central basalts had multiphase eruptions, beginning at 3.77 Ga (30 My after the impact event) with the longest duration of 1.51 Gy; (2) the edge basalts have a ...

We examined 2947 basalt and volcanic glass artifacts from 38 sites in leeward Kohala. Nondestructive energy-dispersive X-ray fluorescence provided initial geochemical characterizations.
Most of the basalt found on Earth was produced in just three rock-forming environments: 1) oceanic divergent boundaries, 2) oceanic hotspots, and 3) mantle plumes and hotspots …
The fourth layer is slightly resistive (12-35 Ω-m), thick, and it is associated with weathered and fractured basalt distributed in the depth range of 26-56 m. The fifth layer in the sequence possesses a relatively very low resistivity values (1-4 Ω-m) and its top surface lies between 20 and 30 m depth.
The distribution of points on the plot reveals the direction and magnitude of the overall influence of the feature on the prediction results. The analysis shows that the BPFRC-CC is negatively correlated with the depth, basalt fibers, and polypropylene fibers, whereas age, water-cement ratio, and environment exhibit a positive correlation.
Our hope was that students might be able to discern patterns in rock distribution, such as how basalt, an igneous rock, makes up the rock formations beneath every ocean. Geologic maps are fundamental tools for …
