Marble is a rock resulting from metamorphism of sedimentary carbonate rocks, most commonly limestone or dolomite. Metamorphism causes variable re-crystallization of the original carbonate mineral grains. The resulting marble rock is typically composed of an interlocking mosaic of carbonate crystals.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO 3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite.

2019年12月1日 · Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. In its pure form, marble is a white stone with a crystalline and sugary appearance, consisting of calcium carbonate (CaCO 3). Usually, marble contains other minerals, including quartz, graphite, pyrite, and iron oxides.

2024年1月4日 · Marble is a metamorphic rock formed from the transformation of limestone or dolomite under extreme heat and pressure. This process, known as metamorphism, alters the original carbonate mineral...

2023年8月21日 · Marble is a type of metamorphic rock that is composed of recrystallized carbonate minerals, usually calcite or dolomite. The physical origins of marble can be traced back to a combination of heat, pressure, and chemical activity that transforms existing sedimentary or igneous rocks into this distinctive rock type.

2025年1月7日 · marble, granular limestone or dolomite (i.e., rock composed of calcium-magnesium carbonate) that has been recrystallized under the influence of heat, pressure, and aqueous solutions. Commercially, it includes all decorative calcium-rich rocks that can be polished, as well as certain serpentines (verd antiques).

2024年7月9日 · In this article we’ll take a close look at marble, covering its formation, characteristics, types, uses, and significance in both natural and cultural contexts. Marble forms from the metamorphism of limestone, a sedimentary rock composed primarily of …

Marbles, geologically defined as metamorphically altered calcareous rocks, are found in the core areas of younger mountain chains formed by the collision of tectonic plates and the consequent uplift and distortion of carbonate sedimentary strata.

2015年7月22日 · Marble is a calcite (calcium carbonate), a type of sedimentary rock, that is heated and subject to fairly high pressure. It is not igneous. I suspect the marbling comes from the different deposition layers as they're laid down, and deformation from …

Marbles are limestones or dolostones that have been metamorphosed. Since metamorphism recrystallizes the individual calcite or dolomite crystals in the parent rock, slightly metamophosed limestones have textures that look slightly blurred compared to a fresh limestone.
