Interbedding (Petrology 💎)
In geology, interbedding occurs when beds of a particular lithology lie between or alternate with beds of a different lithology. For example, sedimentary rocks may be interbedded if there were sea level variations in their sedimentary depositional environment. Intercalation is a special case of interbedding where a layer is variably inserted into an already existing s...

Facies (Petrology 💎)
In geology, a facies is a body of rock with distinctive characteristics. The characteristics can be any observable attribute of rocks and the changes that may occur in those attributes over a geographic area. A facies encompasses all the characteristics of a rock including its chemical, physical, and biological features that distinguish it from adjacent rock. The term "facies" was i...

Joint (geology) (Geology terminology ⛰️)
In geology, and more specifically in structural geology, a joint is a break of natural origin in a layer or body of rock that lacks visible or measurable movement parallel to the surface of the fracture. Although joints can occur singly, they most frequently appear as joint sets and systems. A joint set is a family of parallel, evenly spaced joints...

Diamond inclusions (Mineralogy 💎)
Diamond inclusions are the non-diamond materials that get encapsulated inside diamond during its formation process in the mantle. The trapped materials can be other minerals or fluids like water. Since diamonds have high strength and low reactivity with either the inclusion or the volcanic host rocks which carry the diamond to the Earth's surface, ...

Are you in #EarthScience and interested in improving #AcademicPublishing options in your field? I am preparing a proposal for a PCI Eart Sciences, which would be part of https://peercommunityin.org/ family of journals. The digital infrastructure and brand are there, i have benefited as an author and as an editor from PCI Paleo and I can attest to the high quality and robustness of this platform and process. Being involved doesn’t actually require committing a lot of your time, as it takes years to establish a new journal. At this point it is more about launching it and making it visible, so I am primarily looking for mid-to senior-career collaborators who can help steer publications towards this venue. Especially if you’re in the field of #EnvironmentalScience, #Tectonics, #Petrology, #Mineralogy, #PhysicalGeography, #Hydrogeology, #EarthSystemScience and #Climate you are most welcome as these fields are underrepresented in my network. You can contribute by becoming an editor, pledging a submission, or helping recruit a BigName in your field (maybe that’s you?). Please have a look at https://peercommunityin.org/ or get in touch. #OpenAccess #OpenScience #geoscience #OpenPeerReview

Mélange (Petrology 💎)
In geology, a mélange is a large-scale breccia, a mappable body of rock characterized by a lack of continuous bedding and the inclusion of fragments of rock of all sizes, contained in a fine-grained deformed matrix. The mélange typically consists of a jumble of large blocks of varied lithologies. Both tectonic and sedimentary processes can form mélange. Mélange occurrences are associated with...

Volcaniclastics (Volcanology 🌋)
Volcaniclastics are geologic materials composed of broken fragments of volcanic rock. These encompass all clastic volcanic materials, regardless of what process fragmented the rock, how it was subsequently transported, what environment it was deposited in, or whether nonvolcanic material is mingled with the volcanic clasts. The United State...

Laccolith (Petrology 💎)
A laccolith is a body of intrusive rock with a dome-shaped upper surface and a level base, fed by a conduit from below. A laccolith forms when magma rising through the Earth's crust begins to spread out horizontally, prying apart the host rock strata. The pressure of the magma is high enough that the overlying strata are forced upward, giving the l...

Dunham classification (Petrology 💎)
The Dunham classification system for carbonate sedimentary rocks was originally devised by Robert J. Dunham in 1962, and subsequently modified by Embry and Klovan in 1971 to include coarse-grained limestones and sediments that had been organically bound at the time of deposition. The modified Dunham Classification has subsequently become the ...

Lapilli (Petrology 💎)
Lapilli is a size classification of tephra, which is material that falls out of the air during a volcanic eruption or during some meteorite impacts. Lapilli is Latin for "little stones". By definition lapilli range from 2 to 64 mm in diameter. A pyroclastic particle greater than 64 mm in diameter is known as a volcanic bomb when molten, or a volcanic block when solid. Pyroclastic material...

Aggregate (geology) (Petrology 💎)
In the Earth sciences, aggregate has three possible meanings. In mineralogy and petrology, an aggregate is a mass of mineral crystals, mineraloid particles or rock particles. Examples are dolomite, which is an aggregate of crystals of the mineral dolomite, and rock gypsum, an aggregate of crystals of the mineral gypsum. Lapis lazuli is a type o...

Large igneous province (Geomorphology 🏞️)
A large igneous province is an extremely large accumulation of igneous rocks, including intrusive and extrusive, arising when magma travels through the crust towards the surface. The formation of LIPs is variously attributed to mantle plumes or to processes associated with divergent plate tectonics. The formation o...

Stylolite (Petrology 💎)
Stylolites are serrated surfaces within a rock mass at which mineral material has been removed by pressure dissolution, in a deformation process that decreases the total volume of rock. Minerals which are insoluble in water, such as clays, pyrite and oxides, as well as insoluble organic matter, remain within the stylolites and make them visible. Sometimes h...

QAPF diagram (Petrology 💎)
A QAPF diagram is a doubled-triangle plot diagram used to classify intrusive igneous rocks based on their mineralogy. The acronym QAPF stands for "Quartz, Alkali feldspar, Plagioclase, Feldspathoid ", which are the four mineral groups used for classification in a QAPF diagram. The percentages of the Q, A, P and F groups are normalized, i.e., recalculated so that th...

For those interested in open source tools and software in geochemistry, petrology and related fields, the #Goldschmidt2023 session "Geoscientists’ Little Helpers – small software tools with big impact" is showcasing a wide ensemble of new and existing projects across the community. It's certainly nice to see a spotlight on all of these things enabling new science across the community!
