A nodule is composed of the same material as the surrounding rock along with cementing minerals, while a nodule (such as the flint nodules in limestone) is composed of a different material. Nodules can be shaped like cylinders, flakes, nearly perfect spheres, and anything in between. Most are spherical.

What does the scab look like?

tuberculosis is Usually ovoid or spherical, although irregular shapes are also available… nodules form within already deposited sedimentary strata. They usually form early in the sediment burial, before the rest of the sediment hardens into rock.

Where can I find TB?

There are nodules near and far, Beaches from Western Kazakhstan to CaliforniaOften the size of a cannonball, they are formed by water eroding a piece of sedimentary rock. They almost look artificial. Fossils of many dead creatures have been found in these strange deposits. « 

Are there fossils in the nodules?

Nodules are often misunderstood geological structures.Often mistaken for fossil eggs, turtle shells or bones, they are Not actually a fossil at all But it is a common geological phenomenon in nearly all types of sedimentary rocks, including sandstone, shale, siltstone, and limestone.

Is tuberculosis worth anything?

In general, calcium stones are precious as pearls. Brighter colors and stronger saturation demand higher prices. Circles and ovals are preferable, other shapes are judged by how symmetrical they look. Smoother surfaces, higher gloss and larger sizes also add value.

How long does it take for a scab to form?

« However, our results show that nodules grow at a very rapid rate months to years. » This rapid sealing mechanism could explain why some nodules contain well-preserved soft-tissue fossils that are rarely fossilized under other conditions.

What causes stones in the eyes?

Stones are mostly idiopathic, caused by Degenerative changes in the conjunctiva due to agingSecondary causes include: Allergic or chronic infectious diseases affecting the conjunctival surface, eg, trachoma, allergic keratoconjunctivitis, atopic keratoconjunctivitis.

Why do nodules form around fossils?

Calcite then binds the sand and clay particles together. This happens quickly and helps preserve fossils before the animal or plant decomposes completely. Over time, more and more sediment is cemented togetherforming hard, dense nodules around the fossil.

What are kidney stones?

Kidney stones, commonly known as kidney stones, are small clumps of crystals of different substances, such as salt, calcium, uric acid, and other mineralsThey form hard pebble-like deposits that range in size from the size of a kernel to a grain of salt, or a sugar cube to the size of a ping-pong ball.

What are nodules and tuberculosis?

A tuberculosis is Clearly bound rock bodies in usually softer closed sediments same ingredients. … nodules are hard rock bodies similar to nodules, but with a different composition than the sediments that contain them.
