Exsolution lamellae require slow cooling and a broad range bulk composition. The exsolution of feldspar for example needs to have abundant Na and K to make lamellae. The compound in the most abundance of the bulk composition will be the main part of the crystal. The smaller proportion will be the lamellae. The unmixing happens due to cation size differential. As the mineral cools it is less willing to have high energy random distribution of the elements. Once a liquid cools to its miscibility gap the mineral creates areas of each compound separately. The lamellae align crystalographically.
What else can I help you with?
Name four clastic sedimentary rocks and explain how these rocks form?
Sandstone: formed by the cementation of sand grains. Conglomerate: formed by the cementation of rounded pebbles. Siltstone: formed by the compaction of silt-sized particles. Shale: formed by the compaction of clay and silt particles.
What sedimentary rocks are formed from the remains of plants and animals?
Sedimentary rocks formed from the remains of plants and animals are called organic sedimentary rocks. Examples include coal, formed from the remains of plants, and limestone, formed from the shells of marine organisms.
What are the three kinds of rocks tell how each formed?
Igneous, metamorphic, and sedimentary are the three types of rocks. Sedimentary is formed when layer of mud or silt build up gradually. Igneous is formed when molten magma cools. Metamorphic is formed when a type of rock changes to another type
Where is each type of igneous rock formed?
The Extrusive igneous rock is formed on the earths surface while the Intrusive igneous rock is formed within or inside the earths crust.
According to the following reaction how many grams of sulfur are formed when 37.4 g of water are formed?
To determine the grams of sulfur formed, we need to first identify the balanced chemical equation for the reaction involving sulfur. Once we have the balanced equation, we can use stoichiometry to determine the mass of sulfur formed using the given value of water formed.
What is perthitic texture?
A perthitic texture is an intimate intergrowth of sodic and potassic feldspar resulting from subsolidus exsolution (unmixing of two minerals). Strictly speaking a perthite has blebs or irregular lamellae of sodic feldspar within potassic alkali feldspar, however, the term perthite is often used to describe all types of exsolution in the feldspars. An antiperthite is an intergrowth arising due to exsolution where potassic feldspar is present as blebs or lamellae within a sodic feldspar. The term mesoperthite is used when sodic and potassic feldspars are in broadly equal anbundance. Perthite that can only be observed with the aid of a microscope is known as microperthite. Perthite in which the lamellae are barely visible under a microscope is termed cryptoperthite.
What is The type of lamellae found between osteons?
The type of lamellae found between osteons is interstitial lamellae. These lamellae are remnants of old osteons that have been partially destroyed during bone remodeling.
What are the layers of calcified matrix called?
The layers of calcified matrix in bone tissue are called lamellae. These lamellae are arranged in concentric circles around central canals called Haversian canals, forming the structure known as an osteon or Haversian system.
What are the membranes connecting the Grana?
The membranes connecting the grana in chloroplasts are called stroma lamellae. They connect the thylakoid stacks (grana) and play a role in facilitating communication and transport of molecules within the chloroplast.
What are the matrix rings of compact bone that surround the central canal of each osteon?
The matrix rings are called lamellae and they concentrically surround the central canal (Haversian canal) of each osteon. They form a series of concentric circles, providing structural support and strength to the bone tissue.
What are the layers of calcified matrix?
Concentric lamellae.
What are Layers of calcified matrix?
Concrete lamellae
Where do the hyphae terminate in radiating lamellae?
The hyphae terminate in radiating lamellae in the gills of a mushroom. These gills are found underneath the cap and are responsible for producing and dispersing spores.
Fish can extract oxygen from water using what?
Fish have lamellae in their gills. As the water flows through the gills and over the lamellae, the oxygen is extracted from the water.
Which does not belong lamellae canaliculi circulation or osteoblasts?
It circulation
What is the area between osteons are filled in with what lamellae?
interstitial
What type of bone contains lamellae?
yes it is in spongy and bone
