Basalt is a good raw material for producing "cast stone"."Cast stone" is the basalt after melting casting, crystallization treatment, annealing materials.It is harder and more durable than alloy steel and more resistant to corrosion than lead and rubber.Basalt also plays the role of "lubricant" in an advanced steel casting process, which can extend the life of the casting film.At the same time, basalt can be drawn ...

Many alkali basalts may be formed at greater depths, perhaps as deep as 150200 km. [citation needed] The origin of high-alumina basalt continues to be controversial, with disagreement over whether it is a primary melt or derived from other basalt types by fractionation.

It has greater than 17% alumina (Al 2 O 3) and is intermediate in composition between tholeiite and alkali basalt; the relatively alumina-rich composition is based on rocks without phenocrysts of plagioclase. Alkali basalt is relatively poor in silica and rich in sodium.

The boundaries between alkali rhyolite, rhyolite and dacite, trachyte, phonolite, andesite and basaltic andesite, trachy andesite, tephra-phonolite, basalt, alkali basalt and foidite are based on Pearce's (1996, Fig. 7a-e) revised and redrawn diagram with 10% probability contours. It is important to note that there are overlaps between the

By definition, basalt is an aphanitic (fine-grained) igneous rock with generally 45-55% silica (SiO 2) and less than 10% feldspathoid by volume, and where at least 65% of the rock is feldspar in the form of plagioclase.It is the most common volcanic rock type on Earth, being a key component of oceanic crust as well as the principal volcanic rock in many mid-oceanic islands, including Iceland ...

Trachyte Wikipedia

Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite. The mineral assemblage consists of essential alkali feldspar; relatively minor plagioclase and quartz or a feldspathoid such as nepheline may also be present.. Biotite, clinopyroxene and olivine are common accessory minerals.

Limestone. A part of calcium molecules if being replaced by magnesium, it is known as magnesium lime stone or dolomite limestone. Limestone that will take a polish are considered marbles by most people, but technically, if there are still shells visible or the structure is not crystalline, it is still a limestone.

the alkali-silica reaction increases.At higher concentrations of alkali hydroxides, even the more stable forms of silica are susceptible to attack (Xu 1987). If the alkali concentration is great enough, the alkali hydroxides break stronger silicon bonds found in less reactive aggregates to form the gel reaction product.This explains why
