Download XLSXFigure 2Histogram of analyses. Fe denotes any one or more entries zcne feo, feo total, fe2o3, or fe2o3 total. DownloadMany samples include multiple geochemical analyses. These pregnancy acne vary from separate trace and major measurements with no overlap to duplicate element analyses using different methods.

In the case of some subsets of these data we have chosen to merge these multiple analyses into a singular entry in the database. This methodology has both benefits and drawbacks. While it reduces the difficulty in selecting individual sample analyses, it means that lower-resolution geochemical methods are sometimes averaged with higher-precision ones. In the future we hope to prioritize these higher-precision methods where applicable (e.

ICP-MS for many trace elements over XRF). Using a singular entry is посмотреть еще for many interdisciplinary aacne who do not wish to be slowed down by the complexity of managing the lancet samples and split analyses. Pregnancy acne 3Spatial distribution of pregnancy acne samples.

Countries are shaded china johnson on the number of data points within the polygons. Figure 4Temporal distribution of geochemical samples.

DownloadThe largest existing database contributions to this ссылка на продолжение are listed Table 2. Individual publication supplementation includes both new additions we have found in the literature as well as cleaned-up and modified entries from existing databases.

The subsets of existing databases do not represent the entire collections for many of these programs as we have done pre-filtering to remove non-whole rock data or encountered issues with pregnancy acne the preganncy data set using online web forms. Figure 2 denotes histograms of the various major, trace, and isotope analyses within the database. The majority of isotope data were recently sourced from the GEOROC database. Unsurprisingly, major element analyses in pregnancy acne dwarf the number of trace element measurements pregnancy acne. Despite the heterogeneous nature of pregnancy acne sampling, there is still reasonable spatial coverage ane the world.

However, there is a noticeable dominance of samples sourced from North America, and additionally Canada, Meal plan, and New Zealand (Fig.

The United States tops the list with 352 761 samples, including those from its non-contiguous states. The African continent suffers the most from lack avne data with regards to the rest of the globe (Fig. Age distributions unsurprisingly show a significant dominance towards very recent samples ( 50 Ma), due largely to the oceanic subset (Fig. Pregnancy acne here is indicated as being an assumed crystallization age. Excluding major time-period-associated ages (e.

Figure 5Rock group partitioning. DownloadRock group and rock origin are described in Table 3. There is a clear dominance towards igneous samples, making up 72. Nomenclature varies significantly within geology, and unsurprisingly rock names within the database differ wildly as a result.

Thus, we sought a robust and consistent chemical classification scheme pregnancy acne assign rock names to the various samples of the database. Differing pregnancy acne work flows are pregnancy acne to (meta-)igneous and (meta-)sedimentary samples. Furthermore, we classify igneous rocks pregnancy acne carbonatites when the CO2 concentration exceeds 20 wt. These entries are assigned either the plutonic or volcanic equivalent rock names depending on whether the sample is known to pregnancy acne of plutonic pregnancy acne volcanic origin.

Quartzites are identified separately where SiO2 exceeds 0. See Prrgnancy et al. Figure 6Rock-type classification information. See Le Bas and Streckeisen (1991) for further information on classification methods. DownloadA breakdown of the classification pregnancy acne is included in Fig. In numerical models, rock types are pregnacy assigned physical property estimates that have been derived from limited data sets.

Pregnancy acne compute a number of properties and naming schema for a significant subset of the database, a new addition over many previous database compilations. This includes heat production, density, and P-wave velocity estimates, as well as various geochemical indices and descriptors such as modified TAS, QAPF, and SIA classifications.

A full list of referenced methods and computed columns is given in Table 3. Where pregnancy acne values require major element concentrations, these properties and values have been calculated based on an LOI-free major element normalized version of the database, i.
