MeV Ion beam analysis of granite in 10000 points

The dataset presents 10000 ion-beam-analysis (IBA) measurements of a granite using 2970+-20 keV protons. Figure 1 shows an example of the result. 10,000 points are acquired in a regular 100x100 point grid with 50 µm beam spot size and step-size. Four detectors acquire the data simultaneously for RBS, NRA, PIGE, and PIXE. The description of the end-station and detectors can be found here: <a href="https://doi.org/10.3390/instruments5010010">https://doi.org/10.3390/instruments5010010</a>. Each point on the sample consists of 4 files, four detector spectra. The filename consists of the sample name, three positions in units of nm (X, Y, Z), a rotation in units of µ° followed by an underscore ( _ ) and the type of data contained in the file (RBS, NRA, PIXE, PIGE, or Meta). Only X and Z positions are relevant in this case as indicated in the attached figure. The RBS, NRA, and PIGE detector files contain a header specifying the dead- and live-time followed by two columns. The first column represents the digital channel of the detector. The second column represents the counts acquired in this channel. This format is readable as ASCI by SimNRA7. The PIXE file contains the number of channels in the first row/header and only the counts in the subsequent rows. The channel is given by the row number. This format is readable by GUPIXWIN3. The channels of the detector files can be re-calculated using a calibration shown in the following table 1. Certain drifts in the calibrations are possible, but should be limited to below 2% of the given value. All points are integrated to the same ion dose of 0.07 µC. This corresponds to a Particle*Sr of about 5.0E+09 (RBS detector), 5.4E+10 (NRA). RBS Spectra can be empty or feature a strong low energy background due to excessive scintillation light. Empty spectra can be ignored. The background can be mitigated by ignoring channels <150.   Table 1: Detector calbration enabling a recalculation of channels to energy.

Data from: High species diversity and turnover in granite inselberg floras highlight the need for a conservation strategy protecting many outcrops

Determining patterns of plant diversity on granite inselbergs is an important task for conservation biogeography due to mounting threats. However, beyond the tropics there are relatively few quantitative studies of floristic diversity, or consideration of these patterns and their environmental, biogeographic and historical correlates for conservation. We sought to contribute broader understanding of global patterns of species diversity on granite inselbergs and inform biodiversity conservation in the globally significant Southwest Australian Floristic Region (SWAFR). We surveyed floristics from 16 inselbergs (478 plots) across the climate gradient of the SWAFR stratified into three major habitats on each outcrop. We recorded 1060 species from 92 families. At the plot level, local soil and topographic variables affecting aridity were correlated with species richness in herbaceous (HO) and woody vegetation (WO) of soil-filled depressions, but not in woody vegetation on deeper soils at the base of outcrops (WOB). At the outcrop level, bioclimatic variables affecting aridity were correlated with species richness in two habitats (WO and WOB) but, contrary to predictions from island biogeography, were not correlated with inselberg area and isolation in any of the three habitats. Species turnover in each of the three habitats was also influenced by aridity, being correlated with bioclimatic variables and with inter-plot geographic distance, and for HO and WO habitats with local site variables. At the outcrop level, species replacement was the dominant component of species turnover in each of the three habitats, consistent with expectations for long-term stable landscapes. Our results therefore highlight high species diversity and turnover associated with granite outcrop flora. Hence, effective conservation strategies will need to focus on protecting multiple inselbergs across the entire climate gradient of the region.

Melting and melt segregation processes controlling granitic melt composition

Granitic melt composition is controlled by melting reactions and modified by melt segregation process. This is a fundamental but unresolved issue for granite petrogenesis. To investigate the influence of these two processes on granitic melt compositions, we conducted systematic petrographic and geochemical analyses of melanosome and leucosome samples from the Jindong migmatite in the Indosinian orogen, South China. Petrographic observations and zircon U-Pb geochronology indicate that the Jindong migmatite was formed through water-fluxed melting of the Early Paleozoic gneissic granite (437±2 Ma) during the Triassic (238±1 Ma). The Jindong leucosomes can be divided into lenticular and net-structured types. They show increasing Rb with decreasing Ba and Sr, due to fractionation of K-feldspar and plagioclase during melt segregation. Nd isotope and Th, Y and REE contents of leucosomes reveal the complex behavior of phosphates during melting, recorded by the incongruent melting of apatite with precipitation of monazite and xenotime in the source. The leucosomes have similar Nd isotopic compositions with the source due to early dissolution of monazite. Continued dissolution of apatite caused saturation of monazite and decreased εNd(t) values of melts. This interplay also caused sharply reduction of Th, Y and REE contents in melts with increasing P2O5, when saturation of monazite and xenotime due to dissolution of apatite. Thus, dissolution of accessory phase in the source impacts fundamentally on REE geochemistry and Nd isotope of granites. Such patterns are reflected in granites worldwide, illustrating the strong controls of the melting and melt segregation processes on granitic melt compositions.
