The high pressure TTGs have experienced geotherms lower than 10 °C/km, which are close to modern hot subduction geotherms experienced by young slabs (but around 3 °C/km hotter than other modern subduction zones), whilst the geotherms for the most abundant TTG subseries, medium pressure group, are between 12 and 20 °C/km. [8] Other than hot ...
The source merge S = M(X,Y) of two TTGs X and Y is a TTG created from the disjoint union of graphs X and Y by merging the source of X with the source of Y. The source and sink of X become the source and sink of S respectively. An SPQR tree is a tree structure that can be defined for an arbitrary 2-vertex-connected graph. It has S-nodes, which ...
The BGB consists of locally derived sediments and chemical sediments, but is composed mostly of TTGs and greenstones, as briefly discussed above. [5] Three main lithostratigraphic units are used to divide the BGB. The base contains the Onverwacht, followed by the Fig Tree, and the topmost Moodies Groups. [5]
The processes that form TTGs are debated. Some authors attribute TTG formation to subduction activity, [8] while others attribute the origin of these melts to the direct melting of the lithosphere by mantle plumes. [9] The debate of the origin of the TTGs is a key topic in the debate of when plate tectonics began. [9]
Antibodies to tissue transglutaminase (abbreviated as anti-tTG or anti-TG2) are found in patients with several conditions, including celiac disease, juvenile diabetes, [1] inflammatory bowel disease, [2] and various forms of arthritis.
The location map of the Dharwar Craton. The shaded area represents the Dharwar Craton. Generated from GeoMapApp (Ryan et al., 2009). [1]The Dharwar Craton is an Archean continental crust craton formed between 3.6-2.5 billion years ago (), which is located in southern India and considered the oldest part of the Indian peninsula.
There were two phases forming TTGs, with the first stage at about 2.53 billion years ago [26] and the second one at between 2.52-2.48 billion years ago. [20] [27] The sanukitoid in this terrane formed between the two phases of TTG formation, at about 2.53-2.52 billion years ago. [20] [27]
Appinite is an amphibole-rich plutonic rock of high geochemical variability.Appinites are therefore regarded as a rock series comprising hornblendites, meladiorites, diorites, but also granodiorites and granites.
