웹2024년 4월 10일 · The high Zr contents (>200 ppm) and Zr/Yb values (>12) of the basalts and the Zr vs. Ti diagram (Figure 11a) show the characteristics of within-plate basalts (WPB), which are distinguished from island arc basalts (IAB), and exclude the possibility of subduction zone setting. In addition, ... Basalt is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is … 더 보기 Basalt is composed mostly of oxides of silicon, iron, magnesium, potassium, aluminum, titanium,and calcium. Geologists classify igneous rock by its mineral content whenever possible, with the relative volume … 더 보기 Earth Basalt is the most common volcanic rock type on Earth, making up over 90% of all volcanic rock on the planet. The crustal portions of 더 보기 The common corrosion features of underwater volcanic basalt suggest that microbial activity may play a significant role in the chemical exchange between basaltic rocks and seawater. The significant amounts of reduced iron, Fe(II), and manganese, … 더 보기 • Basalt fan structure – Rock formation composed of columnar jointed basalt columns that have slumped into a fan shape • Basalt fiber – Structural fibres spun from melted basalt • Bimodal volcanism – Eruption of both mafic and felsic lavas from a single volcanic … 더 보기 The mineralogy of basalt is characterized by a preponderance of calcic plagioclase feldspar and pyroxene. Olivine can also be a significant constituent. Accessory minerals present in relatively minor amounts include iron oxides and iron-titanium oxides, such as 더 보기 Weathering Compared to granitic rocks exposed at the Earth's surface, basalt outcrops weather relatively rapidly. This … 더 보기 Basalt is used in construction (e.g. as building blocks or in the groundwork), making cobblestones (from columnar basalt) and in making statues. Heating and extruding basalt … 더 보기
