Where is shale formed
May 9, 2021 · The sediments that make up shale are tightly packed, this arrangement means that shale, unlike limestone, is not a porous rock. One of the shales at Mammoth Cave formed about 320 million years ago as the shallow sea receded and returned, depositing layers of shale above the limestone beds the cave is formed in. 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:A sedimentary rock, oil shale is found all over the world, including China, Israel, and Russia. The United States, however, has the most shale resources.

This is illustrated in Figure 7.2.2, where the parent rock is shale, with bedding as shown.

Heavier particles sink and form sandstone and limestone, while clay and fine silt remain suspended in water. Over time, compressed sandstone and limestone become shale. Shale typically occurs in a broadsheet, several meters ...The only difference between mudstone and shale is that mudstones break into blocky pieces whereas shales break into thin chips with roughly parallel tops and bottoms. Both are made of ancient mud. From the point of view of understanding the ancient conditions of sediment deposition, it is more useful to subdivide mud rocks into siltstone and ...
