Fossils are the remains of ancient plants and animals, like an imprint in a rock or actual bones and shells that have turned into rock. Fossils are found in sedimentary rocks and hold the clues to life on Earth long ago. Limestone: You humans would know so little without rocks ... Importantly, limestone bedrock tells geologists that at the time of formation, that area was a shallow sea. Limestone formed in these environments because its main composition is calcium carbonate, which was deposited when shells and pieces of shells from small shallow water invertebrates settled down to the sea floor.١٩ صفر ١٤٤٢ هـ ...

Modern carbonate sediments are generated in a variety of environments: continental, marine, and transitional, but most are marine.Crystalline limestone fills in the spaces between the other ingredients. Fine-grained limestone, these smooth-looking stones don’t have visible fragments. Typically, these are formed in deeper parts of the sea where the currents are sluggish. Limestone is not just an artifact of ancient seas.limestone formation which has been degraded/dissolved, and the collapse of the limestone cliffs contributes to the reduction in the size of the limestone hills. In a previous survey of the limestone hills in the Kinta Valley, for example, some 40 limestone hills of various sizes have been recorded (Tan, 1988).

Limestone is a very common sedimentary rock consisting of more than 50% calcium carbonate. Although it occurs in many different forms, its origins can be traced back to either chemical or biochemical …Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried, the sediments lose water and become cemented to form rock. Tuffaceous sandstones contain volcanic ash. Clastic Sedimentary Rocks: However, before life did evolve, limestone formed through an inorganic process where rain water falling through a CO2-rich atmosphere reacted to form a weak carbonic acid solution that then reacted with calcium-containing minerals to form calcites. This then washed into the world's oceans to form limestone deposits.It must be 50% calcium carbonate by weight, in the form of calcite. Limestone may also contain other materials, like particles of quartz, feldspar, clay, and more. The presence of these additions is what gives limestone its unique colors and patterns, and which minerals are in limestone depends on where it is sourced from. Marine Limestone Instead of being formed by acidic water slowly eating away at the rock, erosional caves are carved out by a flowing stream of water. The water carries small rocks and sand. These are capable of eroding much harder rock than limestone. Erosional caves can be formed in even the hardest of rock, such as granite.Limestone caves are formed when rainwater seeps through cracks in limestone rock and dissolves it.
