The common limestone varieties include marl, oolite (oolitic limestone), shelly limestone, algal limestone, coral limestone, pisolitic limestone, crinoidal limestone, travertine, onyx, hydraulic limestone, lithographic limestone, and so on. The limestone used in bulk by industries, on the other hand, is a bedded type of sedimentary limestone.

After a covered interval, a gray crinoidal limestone rich in fossil fragments about 5 ft thick (Chappel Limestone) is found at the base of the high cut. Above is about 20 ft or so of lower Barnett Shale, an olive-gray mudstone with a few thin limestone and siltstone layers. Upper Barnett (not exposed in the cut) is a more continuous black shale.Words That Rhyme with crinoidal. Citation styles.

Crinoidal packstones (Fig. 3 B) are characterised by the content of common, mostly crushed echinoderm fragments and occur in three beds in the lower part of the section. Two of them display a horizontal lamination, and the third shows a gradual decrease of bioclasts from a packstone in the lower part to a wackestone in the upper part. ...

Limestone origins. 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 processes that occurred in the geological past, often tens to hundreds of millions of years ago.
