Advantages Of Dacite

Composition Of Dacite

 
Dacite consists mostly of plagioclase feldspar and quartz with biotite, hornblende, and pyroxene (augite or enstatite). The quartz appears as rounded, corroded phenocrysts, or as an element of the ground-mass. The plagioclase in dacite ranges from oligoclase to andesine and labradorite. Sanidine occurs, although in small proportions, in some dacites, and when abundant gives rise to rocks that form transitions to the rhyolites.

The relative proportions of feldspars and quartz in dacite, and in many other volcanic rocks. This defines dacite as having a content of 20% to 60% quartz, with plagioclase making up 65% or more of its feldspar content. However, while the IUGS recommends classifying volcanic rocks on the basis of their mineral composition whenever possible, dacites are often so fine-grained that mineral identification is impractical. The rock must then be classified chemically based on its content of silica and alkali metal oxides (K2O plus Na2O). The TAS classification puts dacite in the O3 sector.

Texture And Geological Formation Of Dacite

In hand specimen, many of the hornblende and biotite dacites are grey or pale brown and yellow rocks with white feldspars, and black crystals of biotite and hornblende. Other dacites, especially pyroxene-bearing dacites, are darker colored. In thin section, dacites may have an aphanitic to porphyritic texture. Porphyritic dacites contain blocky highly zoned plagioclase phenocrysts and/or rounded corroded quartz phenocrysts. Subhedral hornblende and elongated biotite grains are present. Sanidine phenocrysts and augite (or enstatite) are found in some samples. The groundmass of these rocks is often aphanitic microcrystalline, with a web of minute feldspars mixed with interstitial grains of quartz or tridymite; but in many dacites it is largely vitreous, while in others it is felsitic or cryptocrystalline.

Dacite usually forms as an intrusive rock such as a dike or sill. Examples of this type of dacite outcrop are found in northwestern Montana and northeastern Bulgaria. Nevertheless, because of the moderately high silica content, dacitic magma is quite viscous and therefore prone to explosive eruption. A notorious example of this is Mount St. Helens in which dacite domes formed from previous eruptions. Pyroclastic flows may also be of dacitic composition as is the case with the Fish Canyon Tuff of La Garita Caldera.

Dacitic magma is formed by the subduction of young oceanic crust under a thick felsic continental plate. Oceanic crust is hydrothermally altered causing addition of quartz and sodium. As the young, hot oceanic plate is subducted under continental crust, the subducted slab partially melts and interacts with the upper mantle through convection and dehydration reactions. The process of subduction creates metamorphism in the subducting slab. When this slab reaches the mantle and initiates the dehydration reactions, minerals such as talc, serpentine, mica and amphiboles break down generating a more sodic melt. The magma then continues to migrate upwards causing differentiation and becomes even more sodic and silicic as it rises. Once at the cold surface, the sodium rich magma crystallizes plagioclase, quartz and hornblende. Accessory minerals like pyroxenes provide insight to the history of the magma. The formation of dacite provides a great deal of information about the connection between oceanic crust and continental crust. It provides a model for the generation of felsic, buoyant, perennial rock from a mafic, dense, short-lived one.

Uses of Dacite

 
Dacite rock makes aggregate and dimensional stones and can host valuable metal sulfides and other ores. Crushed to make aggregate for roading, railroad ballast, subbases, fills, etc. Also, you can use its gravel on your unpaved walkways, patios, or driveways. In the dimensional stone industry, cut and polished dacite is used to build houses and monuments or make pavers, sculptures, etc.

Some porphyritic dacite to trachyandesites known as red, purple, or Roman Imperial Porphyry from Mons Porphyrites in Egypt were quite popular during the antiquity age among the Romans and Byzantines as dimension and sculpture rocks. Dacitic pumice has uses in landscaping, horticulture, lightweight aggregate, abrasive cleaners, and beauty and personal care.

Tips on Selecting & Ordering of Dacite

How to select the right dacite
Selecting the right dacite can be intimidating. There are many great options on the market, and choosing wisely will help ensure an attractive and durable design for years to come. Enhancing a home’s exterior or interior spaces with dacite allows you to tailor its design to your own style and preferences. When investing in a dacite, there are a few key factors to consider so you find the right fit for your application.

Understand there will be waste
On the jobsite, dacites are cut and fitted to a space and inevitably, there will be unused ends and pieces. Ordering the exact square footage needed for your application without allowing for waste will leave you without enough dacite to complete your project. While the amount of waste varies from project to project, 10 percent or more is a good starting point when estimating how much product you’ll need.

Research & cost
Budget is a factor for any home building or improvement project. Before starting a new project, be sure to create a budget so you can shop for a dacite that fits your bottom line. With so many options available, communicating this established budget will help your dacite distributor narrow down your product choices. Beware of “too good to be true” deals offering dacites well below similar products on the market. If it seems too good to be true, it probably is.

Interior & exterior use
Dacite is a versatile project material that can be used for both indoor and outdoor applications. Choosing the right product for your home means understanding the space in which you’ll use it and the challenges and features of that space. Outdoor dacite applications are often larger spaces such as the front of a house or an outdoor patio or recreation space. Interior dacite walls are often specific areas of a room, such as a fireplace surround or accent wall. When considering which type of faux dacite works best for your project, be sure to consider the setting of the surface you need to cover. Many options on the market are fit for both exterior and interior applications, but make sure to check before making a purchase if your dacite choice is the best fit for your project.
