precipitation from seawater
Sedimentary rocks that formed organically typically contain calcite. Fossils are most likely to be found in sedimentary rocks.
You would most likely find fossils in sedimentary rock. Sedimentary rocks are formed from layers of sediment that accumulate over time, which can help preserve fossils in the rock.
Shale is the sedimentary rock type that is likely to be formed in the most offshore environment. Shale is made up of fine clay particles that settle in quiet water far from the influence of waves and currents.
Evaporites are rock units that are most likely formed from chemical precipitates. These rocks are formed when minerals precipitate out of solution as water evaporates, leaving behind minerals like halite or gypsum.
Quartz is a common example of a monominerallic rock because it is composed almost entirely of the mineral quartz. Other monominerallic rocks include limestone (composed of calcite) and gypsum (composed of gypsum).

Chemical sedimentary rock is created by precipitation of minerals out of, or evaporation from, saturated solutions that are high in dissolved minerals. Rock gypsum and rock salt are two examples.
The rock is most likely sedimentary. Sedimentary rocks are typically formed from the accumulation and compression of sediments, such as sand or clay, over time. These rocks often exhibit layering due to the different materials that have settled and compacted together.
In general, sedimentary rock crystals would be crystals that are found in sedimentary rocks. Normally they are calcite or quartz as they are the minerals most likely to cement sediments to form sedimentary rocks. There is a group of sedimentary rocks called evaporites that include crystals of salt, gypsum, sylvite, glauberite, thenardite, mirabilite and a few others. However, there is a tremendous variety of other minerals that can produce crystals in sedimentary rocks. Geodes from Indiana, Illinois, and Kentucky can have crystals of barite, millerite, sphalerite, galena, fluorite, and aragonite. In other areas of the planet crystals of azurite and malachite can be found in sedimentary rocks. There are many, many other types of crystals that have been found in sedimentary rocks.
Metamorphic
Sedimentary rocks are most likely to result from the process of compacting and cementing particles together. This process involves the deposition of sediments such as sand, clay, and gravel, which are then compacted under pressure and cemented together over time to form sedimentary rocks like sandstone, shale, and limestone.
Oil, Gas, and Coal were sedimentary rocks formed of mostly vegetation. The process that they are buried in usually involves lots of sand, typically coal oil and natural gas are found within sandstones or limestones.
