IPGE

PPGE

Ru-Pd and Os-Pt: in chemistry, this group is referred to as the platinum
metals. Since the 1960 geologists are using the term "platinum-group
elements" (PGE) Marshall1999,Connelly2005georefdatar. In
geochemistry, this group is further divided into two subgroups: Ir-PGE and
Pd-PGE Marshall1999georefdatar with Au often added to the
latter Rollinson1993georefdatar.

datasets

Reference datasets commonly used in the geosciences. These include
standard atomic weights of the elements, a periodic table, a list of minerals
including their abbreviations and chemistry, geochemical data of reservoirs
(primitive mantle, continental crust, mantle, basalts, etc.), decay constants
and isotopic ratios frequently used in geochronology, color codes of the
chronostratigraphic chart. In addition, the package provides functions for
basic queries of atomic weights, the list of minerals, and chronostratigraphic
chart colors. All datasets are fully referenced, and a BibTeX file containing
the references is included.
