Feldspar - Wikipedia

Feldspars (sometimes spelled felspars) are a group of rock-forming aluminium tectosilicate minerals, also containing other cations such as sodium, calcium, potassium, or barium. The most common members of the feldspar group are the plagioclase (sodium-calcium) feldspars and the alkali (potassium-sodium) feldspars. Feldspars make up about 60% of the Earth's crust, and 41% of the … WebFeb 15, 2024 · It can be seen from Figure 6 that as the number of dry-wet cycles increased, the longitudinal wave velocities of the Group A and Group B feldspar sandstones gradually decreased, and the change rates of the wave velocity gradually increased, reaching the maximum values of 16.20% and 33.27%. The decrease in wave velocity indicated that … harish anand md https://pineleric.com
