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.
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.
The type of rock likely formed from layers of sedimentary rock created by silt washing into a lake is shale. Shale is a fine-grained sedimentary rock that typically forms from the compaction of silt and clay particles over time. As these sediments accumulate and undergo lithification, they transform into shale, characterized by its layered appearance and tendency to split along bedding planes.
In caves, you are most likely to find sedimentary rocks, particularly limestone, which is formed from the accumulation of organic materials and minerals. Limestone is especially prone to chemical weathering, leading to the formation of karst landscapes with features like stalactites and stalagmites. Other types of rocks, such as dolostone and gypsum, may also be present in some cave systems.
