Blue Granite Tombstone

This Blue Granite Tombstone is constructed from durable, high-quality granite. Its unique blue color adds a distinguished touch to any memorial or grave marker. Made to withstand the elements, this tombstone is a lasting tribute to your loved one.

blue granite tombstone is the rock with the longest history of application, the widest application, and the most used amount. It is also the most common rock in the earth's crust. Granite is generally light-colored, mostly gray, off-white, light gray, red, and flesh red. The chemical composition is characterized by SiO2 ﹥65%, Fe2O3, FeO, MgO generally ﹤2%, and CaO﹤3%. The main mineral composition is mainly silicon-aluminum light-colored minerals, and iron-magnesium dark-colored minerals are less. Silica-alumina minerals are mainly alkaline feldspar (orthoclase, micro-plagioclase, tropclite), quartz, and acid plagioclase accounting for about 85%, of which the content of quartz is greater than 20%. The content of iron-magnesium minerals is less than 15%, generally 3% to 5%, and the more common ones are biotite and hornblende. Accessory minerals include zircon, sphene, apatite, monazite and so on. When the amount of plagioclase in blue granite tombstone increases, it will gradually transition to granodiorite or quartz diorite; when the amount of quartz decreases and the amount of alkaline feldspar remains unchanged, it will transition to positive feldspar rock. Rocks have fine-grained, medium-grained, coarse-grained granular structures, or porphyritic structures. Generally, dark minerals have a better degree of self-shape, followed by feldspar, and quartz has a poor degree of self-shape. Shallow diagenetic rocks mostly have porphyritic structures (average 2.7g/cm3), porosity is generally 0.3% to 0.7%, and water absorption is generally 0.15% to 0.46%. The compressive strength is about 200MPa, the fine-grained blue granite tombstone can be as high as 300MPa or more, and the bending strength is generally 10-30MPa; the blue granite tombstone has high freeze resistance and high waste rate; the board can be assembled well; the color rate is less than 20%, generally 10 About %, the color tone is mainly light uniform color and beautiful color. The joint development of granite is often regular. If the joint spacing meets the mining requirements, it is not only harmless but also beneficial to the mining of stones with regular shapes.

blue granite tombstone is often produced in the form of rock foundations, rock strains, rock blocks, etc., and is controlled by regional geotectonics. Generally, it is relatively large in scale and widely distributed. In my country, blue granite tombstone stone deposits are not only distributed in fold belts, shields and platform crystalline base areas, but also in large areas where the Mesozoic and Yanshanian continental platforms were activated in eastern my country. Provinces such as Guangdong, Fujian, Jiangxi, and Zhejiang are all well-known blue granite tombstone producing areas.
