Telalginite
Telalginite is a structured organic matter (alginite) in sapropel, composed of large discretely occurring colonial or thick-walled Microorganism, unicellular algae such as ''Botryococcus'', ''Tasmanites'' and ''Gloeocapsomorpha prisca''. Telalginite is present in large algal bodies. It fluoresce brightly in shades of yellow under blue/ultraviolet light. The term "telalginite" was introduced by Adrian C. Hutton of the University of Wollongong. See also *Lamalginite References Sedimentology Organic minerals Petrology {{Microbiology-stub ...

Alginite
Alginite is a component of some types of kerogen alongside amorphous organic matter. Alginite consists of organic-walled marine microfossils, distinct from inorganic (silica)-walled microfossils that comprise diatomaceous earth. Alginite is a complex soil Aggregate (geology), aggregate of algae based biomass fossil, clay, volcanic ash and calcium carbonate. This material contains a complete spectrum of minerals, biological, macro- and micro-organisms helping to turn lands fertile again in regions where soil has been severely degraded in the past. At least two forms of alginite are distinguishable, "alginite A" (telalginite) and "alginite B" (lamalginite). The "A" form contains morphologically distinguishable microfossils while the "B" form is more amorphous and film-like.

Organic Matter
Organic matter, organic material or natural organic matter is the large source of carbon-based compounds found within natural and engineered, terrestrial, and aquatic environments. It is matter composed of organic compounds that have come from the feces and remains of organisms such as plants and animals. Organic molecules can also be made by chemical reactions that do not involve life. Basic structures are created from cellulose, tannin, cutin, and lignin, along with other various proteins, lipids, and carbohydrates. Organic matter is very important in the movement of nutrients in the environment and plays a role in water retention on the surface of the planet. Formation Living organisms are composed of organic compounds. In life, they secrete or excrete organic material into their environment, shed body parts such as leaves and roots and after organisms die, their bodies are broken down by bacterial and fungal action. Larger molecules of organic matter can be formed from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sapropel
Sapropel (a contraction of Ancient Greek words ''sapros'' and ''pelos'', meaning putrefaction and mud (or clay), respectively) is a term used in marine geology to describe dark-coloured sediments that are rich in organic matter. Organic carbon concentrations in sapropels commonly exceed 2 wt.% in weight. The term sapropel events may also refer to cyclic oceanic anoxic events (OAE), in particular those affecting the Mediterranean Sea with a periodicity of about 21,000 years. Formation Sapropels have been recorded in the Mediterranean sediments since the closure of the Eastern Tethys Ocean 13.5 million years ago. The formation of sapropel events in the Mediterranean Sea occurs approximately every 21,000 years and last between 3,000 and 5,000 years. The first identification of these events occurred in the mid-20th century. Since then, their formulative conditions of have been investigated. The occurrence of sapropels has been related to the Earth's orbital parameters (Milankovit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microorganism
A microorganism, or microbe, is an organism of microscopic scale, microscopic size, which may exist in its unicellular organism, single-celled form or as a Colony (biology)#Microbial colonies, colony of cells. The possible existence of unseen microbial life was suspected from antiquity, with an early attestation in Jain literature authored in 6th-century BC India. The scientific study of microorganisms began with their observation under the microscope in the 1670s by Anton van Leeuwenhoek. In the 1850s, Louis Pasteur found that microorganisms caused food spoilage, debunking the theory of spontaneous generation. In the 1880s, Robert Koch discovered that microorganisms caused the diseases tuberculosis, cholera, diphtheria, and anthrax. Microorganisms are extremely diverse, representing most unicellular organisms in all three domains of life: two of the three domains, Archaea and Bacteria, only contain microorganisms. The third domain, Eukaryota, includes all multicellular o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Algae
Algae ( , ; : alga ) is an informal term for any organisms of a large and diverse group of photosynthesis, photosynthetic organisms that are not plants, and includes species from multiple distinct clades. Such organisms range from unicellular microalgae, such as cyanobacteria, ''Chlorella'', and diatoms, to multicellular macroalgae such as kelp or brown algae which may grow up to in length. Most algae are aquatic organisms and lack many of the distinct cell and tissue types, such as stomata, xylem, and phloem that are found in embryophyte, land plants. The largest and most complex marine algae are called seaweeds. In contrast, the most complex freshwater forms are the Charophyta, a Division (taxonomy), division of green algae which includes, for example, ''Spirogyra'' and stoneworts. Algae that are carried passively by water are plankton, specifically phytoplankton. Algae constitute a Polyphyly, polyphyletic group because they do not include a common ancestor, and although Eu ...

Botryococcus
''Botryococcus'' is a genus of green algae. It is a microscopic or semi-microscopic alga that is found in freshwater habitats worldwide. It consists of colonies of cells in an irregular, gelatinous matrix. ''Botryococcus'' produces high amounts of oil, which often make the colonies colored yellowish to reddish. When seen with a microscope, colonies release oil under the pressure of a cover slip. Because of its high amounts of oil, ''Botryococcus'' is of interest to the field of biotechnology, as it is a promising source of biofuel. In addition to its current biosynthetic capabilities, fossils of the genus are known since Precambrian times, and form the single largest biological contributor to crude oil, and are a major component of oil shales. Taxonomy The genus and its holotype were described in 1849 by Friedrich Traugott Kützing. Description ''Botryococcus'' consists of irregularly shaped colonies of cells; in some species or when old, the colonies may be composed of subco ...

Tasmanite
Tasmanite is a sedimentary rock type almost entirely consisting of the prasinophyte alga ''Tasmanites''. It is commonly associated with high-latitude, nutrient-rich, marginal marine settings found in Tasmania. It is classified as marine type oil shale.Hutton, A.C. 1987. Petrographic classification of oil shales // Intern. J. Coal Geol. 1987. Vol. 8. P. 203–231. It is found in many oil-prone source rocks and, when present, contributes to the oil generation potential of the rock. Some sources also produce a red-brown translucent material similar to amber which has also been called tasmanite. In 1865, Professor A. J. Church, near the floodplain of the Mersey River (Northern Tasmania), found translucent reddish-brown or brown samples of an unknown mineral resembling amber embedded in shale in one of the small Tasmanite deposits. These differences ultimately amounted to up to 40% of the main rock and had the appearance of narrow, scaly lenses, difficult to separate from the main r ...

Lamalginite
Lamalginite is a structured organic matter (alginite) in sapropel, composed of thin-walled colonial or unicellular algae that occur as distinct laminae, cryptically interbedded with mineral matter. It displays few or no recognisable biologic structures. Lamalginite fluoresce brightly in shades of yellow under blue/ultraviolet light. The term of lamalginite was introduced by Adrian C. Hutton of the University of Wollongong.

Sedimentology
Sedimentology encompasses the study of modern sediments such as sand, silt, and clay, and the processes that result in their formation (erosion and weathering), transport, deposition and diagenesis. Sedimentologists apply their understanding of modern processes to interpret geologic history through observations of sedimentary rocks and sedimentary structures. Sedimentary rocks cover up to 75% of the Earth's surface, record much of the Earth's history, and harbor the fossil record. Sedimentology is closely linked to stratigraphy, the study of the physical and temporal relationships between rock layers or strata. The premise that the processes affecting the earth today are the same as in the past is the basis for determining how sedimentary features in the rock record were formed. By comparing similar features today to features in the rock record—for example, by comparing modern sand dunes to dunes preserved in ancient aeolian sandstones—geologists reconstruct past environm ...

Organic Minerals
An organic mineral is an organic compound in mineral form. An organic compound is any compound containing carbon, aside from some simple ones discovered before 1828. There are three classes of organic mineral: hydrocarbons (containing just hydrogen and carbon), salts of organic acids, and miscellaneous. Organic minerals are rare, and tend to have specialized settings such as fossilized cacti and bat guano. Mineralogists have used statistical models to predict that there are more undiscovered organic mineral species than known ones. Definition In general, an organic compound is defined as any compound containing carbon, but some compounds are excepted for historical reasons. Before 1828, chemists thought that organic and inorganic compounds were fundamentally different, with the former requiring a vital force that could only come from living organisms. Then Friedrich Wöhler synthesized urea by heating an inorganic substance called ammonium cyanate, proving that organic compounds ...
