 What is Rock ? The world of rocks is vast and varied, consisting of numerous distinct types that form the foundation of the geologic record. Rocks are made of various minerals that have been compressed or melted together over the eons, forming a hard substance that does not dissolve or corrode easily. Rocks of all kinds are present throughout the Earth’s crust, from its shallowest surface to its deepest depths. It is important to understand different types of rocks in order to better understand the processes in the Earth’s history, as well as its present state.   The three major types of rock are igneous, sedimentary, and metamorphic, each with its own distinct characteristics. Igneous rocks are formed when magma or lava cools and solidifies, whilst sedimentary rocks are formed by the compression of pieces of sediment (such as sand and gravel) that have been carried away by water or wind. Metamorphic rocks are created when heat and pressure act on existing rocks, transfor...

  What is a meteorite and what are the different types? Meteorites, interplanetary rocks that enter Earth’s atmosphere and reach the surface, are a hot topic of scientific study in the 21st century. They are composed of minerals and organic materials from outer space, and can offer scientists a glimpse into the history of the universe and of our own planet. Scientists categorize meteorites in three main types.   The first type of meteorite is the iron-rich meteorite. This type is composed primarily of iron and nickel, often with small amounts of other metals mixed in. Iron meteorites, also known as siderites, typically have a much higher density than other rocks, and are often seen on the surface of Earth as they have had little to no weathering. Iron meteorites are thought to have originated in the core of other planets, with their components having been blasted free by asteroid impacts or other disruptions.   The second type is the stony-iron meteorite, which co...

The fascinating history of peridot peridot pronunciation The olivine mineral group consists of two end-members, forsterite (Mg2SiO4) and fayalite (Fe2SiO4). Peridot, a member of the orthorhombic system, is characterized by thick crystals with wedge-shaped terminations, an oily lustre, and a hardness of 7. It has an imperfect cleavage and a specific gravity of 3.34, with a birefringence of 0.036. Its pleochroic colours are weak, with one ray inclining more to yellow than the others. An iron content of 12-15% gives a good, bright green colour, and traces of chromium or nickel may enhance it. The absorption spectrum of peridot shows three distinct bands in the blue area due to iron, with a narrow core at 497 nm. Anderson & Payne also report vague, weak bands in the orange at 635 nm and in the green at 529 nm. With the help of a 10 lens, these features can easily be detected. Additionally, the iron content inhibits luminescence, and the occasional cat's-eye is found. By using a spe...

 Spectral analysis with FTIR: tips and tricks Fourier-transform infrared spectroscopy (FTIR) is a method used to study the vibrational structure of samples, from either an atomic or molecular level. FTIR has the advantage of being able to monitor the structure and properties of a material without the need for calibration, thus it is a versatile technique with advantages in terms of speed, non-destructive testing, safety, and cost. Additionally, FTIR has had huge success in industries such as material, food, and pharmaceutical science, due to its broad absorbance ranges of infrared radiation.  FTIR works by directing infrared radiation from instrument sources such as ribbons, wires, lamps, or globes through the sample, then allowing it to pass through a detector. This signals pass through the sample, creating a ‘fingerprint’ of the structure of the sample due to the infrared radiation having interacted with the vibrational structure of the sample’s molecular bonds. FTIR is capa...

 When questioning the unknown, Raman spectroscopy is the go-to! Raman Spectroscopy is a powerful analytical tool in the study of molecular structure. Though traditionally used in chemistry, this technique is becoming increasingly employed in other scientific fields such as biochemistry, food science and environmental science. Raman spectroscopy operates on the principle of inelastic scattering of photons by molecules. This physical phenomenon enables the characterization of molecular structures and can be used to differentiate between compounds of similar molecular makeup.   At the heart of Raman Spectroscopy is the inelastic scattering process which occurs when radiation is directed at a sample. During this process, some part of the radiation energy is shifted to and from the molecules, thus resulting in the emission of secondary radiation with a different energy. This is what is referred to as the Raman shift, and the intensity and frequency of the radiation indicate the...
