I am a chemical sedimentologist: I study how and why chemical sediments form and lithify, with the goal of better understanding how chemical sedimentary rocks (e.g., carbonates, chert, iron formations ...

Areas of sedimentology and stratigraphy that currently motivate the research our faculty and students include: (i) mechanistic understanding of sediment formation, deposition, and lithification ...

The study shows that the petrographic, geochemical and spectroscopic features in the graphite (the crystalline form of carbon) found in the Saglek-Hebron chemical sedimentary rocks are in fact ...

This used to be sand and other sediment - that's why it is called sandstone - which is a type of sedimentary rock. Sedimentary rocks are formed when pieces of rock are eroded, or worn away ...

This academic year, Scripps Institution of Oceanography at UC San Diego welcomes nine new faculty members and researchers to ...

Researchers at Bristol and Royal Holloway, University of London developed a 3-dimensional forward sediment model, CARB3D+, which is unique in its ability to predict where and which chemical and ...

Quartz is made of the chemical elements silicon and oxygen ... There are three main types of rock — igneous, sedimentary and metamorphic — with varying mineral mixes depending on where and ...

Relative dating to determine the age of rocks and fossils Geologists have established a set of principles that can be applied to sedimentary and volcanic rocks that are exposed at the Earth's ...

Minerals are naturally occurring, solid, and inorganic substances that have a definite chemical composition (or range of compositions) and a regular internal atomic arrangement. Southwestern Ohio's ...

Petrology is the study of the macroscopic and microscopic mineralogical and chemical composition of rocks. In addition to assessing sedimentary, igneous, and metamorphic rocks that are accessible ...

A chemical explosion at Sydney University has sent three people to hospital. A worker was reportedly transporting chemicals when a reaction occurred in the bucket, causing a 'vapour cloud' and ...
