A gabbroid typically has over 35% mafic minerals, mostly pyroxenes or olivine, while a dioritoid typically has less than 35% mafic minerals, which typically includes hornblende. [11] Gabbroids form a family of rock types similar to gabbro, such as monzogabbro, quartz gabbro, or nepheline-bearing gabbro. Gabbro itself is more narrowly defined ...
A dioritoid typically has less than 35% mafic minerals, typically including hornblende, while a gabbroid typically has over 35% mafic minerals, mostly pyroxenes or olivine. [9] The name diorite (from Ancient Greek διορίζειν , "to distinguish") was first applied to the rock by René Just Haüy [ 10 ] on account of its characteristic ...
Diabase (/ ˈ d aɪ. ə ˌ b eɪ s /), also called dolerite (/ ˈ d ɒ l. ə ˌ r aɪ t /) or microgabbro, [1] is a mafic, holocrystalline, subvolcanic rock equivalent to volcanic basalt or plutonic gabbro.
"Na Na Na (Na Na Na Na Na Na Na Na Na)" has been met with generally positive critical enthusiasm. Spin ' s William Goldman described "Na Na Na" as an "in-your-face punk anthem with blistering guitar leads, an epic breakdown, and Gerard Way's sneering delivery", and added, "it's classic MCR and it's all hinged on an unforgettable, hockey-arena ...
Baddeleyite was first found in Sri Lanka in 1892. It can be found in numerous terrestrial and extraterrestrial rocks. Some of these terrestrial rocks are carbonatite, kimberlite, alkaline syenite, some rocks of layered mafic intrusions, diabase dikes, gabbroid sills and anorthosite. [5]

The main cations in the smectite interlayers are Na + and Ca 2+. The sodium cations are responsible for the highest swelling of smectite while calcium ions have lower swelling properties. Calcium smectite has significantly less swelling capacity than sodium smectite but is also less prone to shrinking when desiccated.
An obelisk is a microscopic genetic element that consists of a type of infectious agent composed of RNA.Described as a "viroid-like element", they consist of RNA in a circular rod shape without any protein shell coating.
