Environments of line deposition | Journal of Sedimentary .

Abstract. Lines may be divided on the basis of their depositional environments into three categories: 1) platform, 2) basin, 3) geosynclinal. Platform lines are thin, widespread, light colored, fossiliferous lines which are often dolomitized. Basin lines of the open basin type are lithologically similar to.

Line - Wikipedia

Line is a sedimentary rock, composed mainly of skeletal fragments of marine organisms such as coral, forams and molluscs. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). About 10% of sedimentary rocks are lines. The solubility of.

Line origins — Science Learning Hub

Sep 28, 2012 . The soft parts decay, leaving only the hard shells (exoskeletons or tests), which typically become broken down by current action and biological predators. Over long periods of time, the loose skeletal sediments are transformed into bioclastic line by the addition of a chemically precipitated carbonate.

Line - Sedimentary rocks - Sandatlas

These tests sink to the bottom of oceans or other waterbodies and form a limy sediment (named ooze if the tests are microscopic) which becomes line after burial and lithification. However, some detrital lines (oolites) are composed of abiogenic particles like ooids. Biogenic line may grow in situ by the.

Line is a sedimentary rock

Line is a sedimentary rock, which means it was formed from small particles of rock or stone that have been compacted by pressure. Sedimentary rock is important because it often contains fossils and gives clues about what type of rock was on the Earth long ago. Just like a tree's rings tell a lot about its environment,.

Line | Sedimentary Rocks in Devonian | Alamo Impact Project

The characteristics of marine lines change as you move from shallow- to deep-water environments. The shallowest forms of line are found within the peritidal zone, the area above low tide and extending upland. Below the low tide line is the subtidal zone, which extends out to the deepest environments and can.

. common carbonate rocks. Most of what people call " line" is largely or exclusively micrite. As with clay (shale) it is deposited in generally quiet water, and appears in any environment where those conditions exist. This specimen could have come from a tidal lake, or a subtidal lagoon, or some similar environment.


This fossiliferous line is dominated by crinoids (which look like little buttons) and bryozoans (the branched pieces). There are also a few brachiopod shells in this nice sample.
