COMO SE FORMA A PEDRA NATURAL? pedra paisaxística

Pedra natural é un dos materiais máis utilizados nas casas e xardíns. Pero xa te pareches a preguntar de onde proceden as túas baldosas, ladrillos ou pisos de pedra en particular?

Natural stone was created thousands of years ago when the Earth was just a ball of mineral gases. As these gases began to cool down, they compressed and solidified to form the world we know today. It was during this process that natural stone was formed – the type of stone created depends on what type of minerals were combined at that time. This was a slow process that occurred over millions of years. As the Earth began to settle, many of these seams of stone were gradually pushed to the surface by heat and pressure, creating the large formations we see today.

Stone can come from anywhere in the world, and the type of stone is determined by its origins. There are quarries in America, Mexico, Canada, Italy, Turkey, Australia, and Brazil, as well as many other countries around the globe. Some countries have multiple natural stone quarries, whilst others only have a few. Let’s look in closer detail at where particular stones originate and how they were formed.

Mármore

Mármore is the result of limestone that has been altered through heat and pressure. It’s a versatile stone that can be used on virtually anything – statues, stairs, walls, bathrooms, counter tops, and more. Usually seen in white, marble is also common in black and grey tints, and has great weather endurance.

Cuarcita

Cuarcita orixínase a partir da pedra arenisca que foi alterada pola calor e a compresión. A pedra vén principalmente en branco, pero tamén se pode atopar con tons marróns, grises ou verdosos. É un dos tipos de pedra naturais máis duros, polo que é unha excelente opción para fachadas de edificios, encimeras e outras estruturas que requiren pedras resistentes.

Granito

Granito orixinalmente era unha pedra ígnea que fora exposta ao magma (lava) e alterada pola exposición a diferentes minerais. A pedra atópase habitualmente en países que nalgún momento experimentaron unha gran actividade volcánica e está dispoñible nunha gran variedade de cores desde negro, marrón, vermello, branco e case todas as cores intermedias. O granito é unha excelente opción para cociñas e baños polas súas calidades antibacterianas.

Pedra calcaria

Pedra calcaria é o resultado da compresión de corais, cunchas e outras especies oceánicas xuntas. Hai dous tipos de pedra caliza, un tipo máis duro que está cheo de calcio e un tipo máis brando con máis magnesio. A pedra caliza dura utilízase a miúdo na industria da construción, ou triturada e utilizada no morteiro debido á súa calidade impermeable.

Pedra Azul

Pedra Azul is sometimes referred to as basalt, and is one of the most common natural stones around the world. Bluestone forms through the alteration of lava, and because of this, is one of the closest stones to the Earth’s surface. Basalt is generally darker in colour, and is used as house roofing and floor tiles because of its hard texture.

Lousa

Lousa creouse cando os sedimentos de xisto e lodo foron alterados pola calor e a presión. Dispoñible en cores de negro, morado, azul, verde e gris, a lousa converteuse nunha opción popular para cubertas, xa que se pode cortar finamente e soportar temperaturas frías cun mínimo dano. A lousa tamén se usa a miúdo como baldosa debido á súa natureza duradeira.

Travertino

Travertino is created when floodwaters wash through limestone, leaving mineral deposits throughout. As it dries out, the extra minerals solidify to gradually create a much denser material called travertine. This stone is good as a replacement for marble or granite, as it’s much lighter and easier to work with, yet still durable. For this reason travertine is often used on floors or walls, and is estimated to last around fifty years if maintained regularly.
