Limestone is one of the most beautiful natural stones used for Limestone Floor Tiles Brisbane, they are made from many different limestones from every corner of the Earth, but sometimes we don’t notice the wonderful limestone formations right here, virtually on our own doorstep. The three most important limestone found in and around the United Kingdom are:
1. Cretaceous era Limestone – 65-145 million years old
These are the various chalks that dominate much of South East England, such as the North and South Downs. Chalk is a fine-grained white porous rock, composed from the fossilized remains of marine organisms. Chalk is generally too soft to be used for limestone floor tiles or any other building purposes, but is used a lot in the cement-making process. There are also many bands of Flint occurring throughout the rock formations. The most famous chalk formations in this area can be seen in the white cliffs around Dover.
2. Jurassic era Limestone – 196-145 million years old
These occur in and around the Cotswolds, with a pale brown colour, it is also know as “honey” or “Golden” limestone. They are much softer and more porous than the Carboniferous Limestone and occur in Limestone beds several metres thick. These are important as building stones, especially around the Cotswolds and they are sufficiently well formed to be used as freestones. They are not usually strong enough to be used in industrial construction, but are often pure and strong enough to be used for making Limestone Tiles.
3. Carboniferous era Limestone – 299-359 million years old
This is a solid and dense limestone rock of low porosity, and mainly occurring in thick beds. Carboniferous era Limestones have prominent vertical joints, they can be easily spilt into blocks for use as building stone, limestone floor tiles and limestone flooring. Carboniferous Limestone can be found widespread around the Peak District, Mendips and Yorkshire Dales. These type of Carboniferous limestone landscapes contain most of the potholes and natural cave systems in Great Britain. Carboniferous limestone is either a fine calcite mud, precipitated from warm shallow seas, or a shelly limestone, formed by fragments of animals such as corals and marine organisms. It is a very hard rock, and is commonly used for Limestone flooring and Limestone Tiles, but can also be used for cement making because it is often quite pure, and as a source of calcium carbonate for the chemical industry.
