SEDIMENTARY ROCK
Sedimentary rock is rock that has formed from sediment. Most fossils are found in sedimentary rock.

A kind of sedimentary rock consisting mainly of calcium carbonate minerals.
line spectrum - (n.)
The pattern of colored lines emitted by an element.

sedimentary rocks (NASA Thesaurus) Rocks resulting from the consolidation of loose sediments that have accumulated in layers, e.g.

"The Shape Of The Phanerozoic Marine Palaeodiversity Curve: How Much Can Be Predicted From The Sedimentary Rock Record Of Western Europe?". Palaeontology 50 (4): 765-774. doi:10.1111/j.1475-4983.2007.00693.x.

Sedimentary rock is formed from the accumulation of sediment that becomes compacted together. Nearly 75% of the continental surfaces are covered by sedimentary rocks, although they form only about 5% of the crust.

When microorganisms die, the complex organic molecules that they contain frequently degrade into PAHs which often are associated with ancient sedimentary rocks, coals and petroleum on Earth and can be common air pollutants.

BRECCIA - Clastic sedimentary rock composed of angular clasts in a consolidated matrix.

Real geodes are baseball-sized, hollow rocks that start out as bubbles in volcanic or sedimentary rock.

Sedimentary rocks and the fossil record were formed, according to this view, during the flood of Noah's day. Biblical literalists represent one expression of the catastrophist school of thought.

Magnetofossils: Small grains of magnetite occurring in sedimentary rocks and thought to have been produced by bacteria. (Some bacteria, called magnetobacteria, make magnetite, presumably as an aid to determining directions.) ...

Deposits of sedimentary rocks suggest erosion and transport of material from higher to lower ground. Indeed, the highlands surrounding Hellas are well known to have hosted volcanic activity and sedimentary processes over time.

The sialic or upper crust, of which the continents consist, is made up of igneous and sedimentary rocks whose average chemical composition is similar to that of granite and whose density is about 2.7.

The middle figure shows a composite of local gravity and magnetic field variation data to image a 112-mile wide relic meteor crater in Yucatan that presently lies below several hundred meters of sedimentary rock.

Over time, excess carbon became locked in fossil fuels, sedimentary rocks (notably limestone), and animal shells. As oxygen was released, it reacted with ammonia to create nitrogen; in addition, bacteria would also convert ammonia into nitrogen.

a common mineral in some metamorphic rocks, composed mainly of calcium and magnesium; it occurs from the conversion of dolomite (a sedimentary rock), silica, and water

Petrology studies rocks, which are aggregates of minerals, and the conditions they form in. Petrology focuses its attention on the three types of rocks: igneous, metamorphic and sedimentary rocks.

Comets probably formed at the same time as the Sun and planets, about 4.5 billion years ago. But many of them were kicked far from the Sun by the powerful gravity of the outer planets. The make up comets is found in sedimentary rocks on Earth.

Also, growth rings in ancient corals about 400 hundred million years old show that the day was only 22 hours long so that there were over 400 days in a year. In July 1996 a research study reported evidence, from several sedimentary rock records ...
