Magma transport through the Earth’s crust occurs dominantly via sheet intrusions, such as dykes and cone-sheets and is fundamental to crustal evolution, volcanic eruptions and geochemical element cycling. However, reliable methods to reconstruct flow di
Nevertheless, some aspects of the compositional rela- tionships among the Aar massif intrusions can be explained as effects of fractional crystallization from a granitic parent magma. The very low phosphorous of Brgr may have been caused by earlier apatite crystallization in the cAgr. Simi- larly,...
This observation cannot be explained by higher bulk susceptibility in carbonatite, because carbonatite bulk susceptibilities are generally low in the southern location, as confirmed both in outcrop with a handheld susceptibility meter (Fig. 6a) and through subsequent laboratory measurements (see ...
The high diversity of the Yaw Formation palynoflora, despite well-marked seasonality, is explained by its crossroads location for plant dispersals between India and Asia. Keywords: Bioclimatic analysis, Diversity, Monsoon, Palynology, Sequence biostratigraphy, Southeast Asia ...
A typical household contains tens if not hundreds of microprocessor devices, which can be found within central heating systems, wrist watches, washing machines, car engines, televisions, fixed-line telephones, radios, cookers, dishwashers, clocks, computers, set-top boxes, games consoles, keyboards,...
followed by a simultaneous pressure decrease and temperature increase to 8/850°C and subsequent retrogression via decompression-cooling to 4–5 kbar at – evolution of granulites of the Beit Bridge Complex (Limpopo Belt, South Africa); constraints from quantitative phase diagrams and geotectonic imp...
Windows, window blinds, ventilation, air conditioning and heating can be operated automati- cally and according to the individual inhabitants wishes, depending on the current weather situation and the tem- perature difference between inside and outside the house as well as time of day. Every ...
S2). This discrepancy may be partly explained by the expression of OTX2 in undifferentiated hESC 29. Given the caudal neural identity of SB/CHIR-treated hPSCs and their neural derivatives, we have coined this progenitor population as CNPs. Figure 2 Open in figure viewerPowerPoint Gene ...
(2015) favor an asthenospheric source coupled with thermal erosion of strongly metasomatized lithosphere and/or intense asthenosphere–lithosphere interaction. The less primitive nature of some of these rocks was explained by temporary stagnation and early polybaric fractionation of olivine, ...
Various temperature parameters, during the freezing and heating runs were reproducible to ± 0.1° and ± 1 °C, respectively. The temperatures of the measured phase transitions include first melting temperature (Tfm), ice-melting temperature of the last ice crystal (Tm-ice), melting temperature ...
