Marble is metamorphosed limestone.
Reef Limestone
No, the limestone is not magnetic due to the magnetic fields in the stone itself.
Jurassic Coralline Limestone and Oolitic Lime Stone

Redwall Limestone.
Marble is formed when limestone is subjected to pressure and great heat.
Reef Limestone
Caves in limestone are typically formed through a process called karstification, where acidic groundwater dissolves the limestone rock over time, creating cavities and passageways. This process is enhanced by the presence of fractures and faults in the rock that allow for the water to flow and erode the rock more easily. Over millions of years, this continuous erosion leads to the formation of cave systems within the limestone bedrock.
Because the building is made of limestone, and the shells became integral to the limestone as it was being formed, but they don't erode as quickly as the limestone in the rain.
Shell+Stone= Limestone on Doodle God.
Oolite is sometimes also known as 'Egg Stone'. It is a limestone formed from ooids, spherical grains found in concentric layers.
Limestone is a sedimentary stone. This means it is naturally comprised over time from other natural substances such as shells and skeleton pieces that may have been formed on the sea bed.

Marble was once Limestone.

shell + stone = limestone!
Limestone is a sedimentary rock formed of calcite or calcium carbonate deposits from ancient sea life. Sandstone is a metamorphic rock formed from sand which has been solidified by some geologic process. Quartzite, for example, is a type sandstone formed from solidified grains of quartz sand.
The first is a round green object called a lime. The second often larger subunit is called stone.
