(1) Laser ablation U-Pb dating is a widely used geochronological technique for dating U-bearing accessory minerals (i.e., zircon, monazite, baddeleyite, xenotime, and titanite) and is generally applied to constrain the provenance of sedimentary rocks.

The most common type of rock exposed on Earth's surface is sedimentary rock. However, Earth's crust is formed predominantly of the other two main types of rock, igneous rock and metamorphic rock. Sedimentary rocks are produced by the weathering of old rocks, which breaks apart the rocks into particles or fragments called sediment.

sedimentary rock, Rock formed at or near the Earth's surface by the accumulation and lithification of fragments of preexisting rocks or by precipitation from solution at normal surface temperatures. Sedimentary rocks can be formed only where sediments are deposited long enough to become compacted and cemented into hard beds or strata.

Sedimentary rock - Clastic, Chemical, Organic: Conglomerates and breccias are sedimentary rocks composed of coarse fragments of preexisting rocks held together either by cement or by a finer-grained clastic matrix. Both contain significant amounts (at least 10 percent) of coarser-than-sand-size clasts. Breccias are consolidated rubble; their clasts are angular or …

Sedimentary Rocks. Sedimentary Rocks: Definition and Formation. Sedimentary rocks are rocks that are formed by the deposition and cementation of miniscule particles on the earth's surface at low temperatures.; The sediments are derived from the weathering and erosion of pre-existing rocks and are transported by water, air, or ice to the location where they solidify and accumulate.

Sedimentary rock is formed over millions of years. It is built up layers. Fossils can be found in sedimentary rock. Fossilisation. If a marine organism dies, falls to the ocean floor and doesn't rot away, it may form a fossil. Over time, sediment is layered on top of it.

Weathering and Erosion. Sedimentary rocks are formed by the weathering, erosion, deposition, and lithification of sediments. Sedimentary rocks can be composed of pieces of other rocks, which are broken down by the process of weathering.. Weathering occurs in two different ways: First, rocks can be physically broken into smaller pieces (e.g. two rocks bump into each other, and …

Detrital zircon U–Pb and Hf isotopic data for meta-sedimentary rocks … It is generally accepted that the youngest concordant age of detrital zircons from sedimentary rocks can be used to constrain the maximum depositional age, which in turn define the maximum age of metamorphism of these rocks (e.g. Fedo et al., 2003, Nelson, 2001, Williams, 2001).

Clastic sedimentary rocks are rocks that are formed from bits and pieces of previously existing rock that are compacted or cemented together.
