SHRIMP-RG sample preparation and analyses were conducted by Ryan McAleer. The whole rock geochemistry and uranium-lead (U-Pb) isotopic data constrain the age of a mapped meta-plutonic unit in the eastern Adirondack Mountains of New York. The data release contains six files, including one metadata file and 5 comma-delimited (CSV) files. The CSV files include the following: EagleLake_SHRIMP_data.csv, EagleLake_SHRIMP_data_dictionary.csv, EagleLake_SHRIMP_summary.csv, EagleLake_WR_data.csv, and EagleLake_WR_data_dictionary.csv.

This data release accompanies the Data Series report 'Compilation of new and previously published geochemical and modal data for Mesoproterozoic igneous rocks of the St. Francois Mountains, southeast Missouri’ (https://doi.org/10.3133/ds1080). The compilation includes recently acquired as well as previously published geochemical and modal petrographic data for igneous rocks in the St. Francois Mountains, southeast Missouri, and supports an ongoing effort to understand the regional geology and ore deposits of the Mesoproterozoic basement rocks of southeast Missouri, USA. This data release includes geochemical data that are (1) newly acquired by the U.S. Geological Survey (USGS) and (2) compiled from numerous sources published during the last fifty-five years. These data are required for ongoing petrogenetic investigations of these rocks. This data release also contains selected data for Mesoproterozoic igneous rocks that were previously published in three U.S. Geological Survey (USGS) data releases (Day and Granitto, 2014; Day, Granitto, and others, 2016, and Granitto and others, 2017). These previously published USGS products include sample description, sample locations, and major oxide and trace element determinations for Mesoproterozoic igneous samples, as well as other samples collected in southeast Missouri by the USGS from the late 1980s through 2017. In this data release, field notes pertinent to the 2015-2017 samples, prefixed with MO15, MO16, and MO17 and where '_xxx' is the individual sample number, are included as Appendix 1 in the Microsoft Excel file 'DS1080_appendix1_MO15_17_Field_Notes.xlxs' file and in its derivative ASCII tab-delimited text file. Data attributes in these files include the field number (Field_ID), location (Latitude, Longitude), rock type (Rock_Type), description of the rock and (or) outcrop from which the sample was collected (Rock_Description), the alteration minerals observed in the field (Alt_Minerals), and their mode of occurrence (Alt_Style). For completeness, the field notes files also include descriptive information for samples without corresponding geochemical analyses. Prior investigations report compositional data for Mesoproterozoic igneous rocks in the St. Francois Mountains that contribute significantly to the understanding of the geochemistry of the region. These data have been compiled during our investigations and are reported herein. For an individual sample to be included in our compilation, a minimum data set consisting of a sample identification value, location information, and a major oxide analysis was required. Additional data were included when available. As a result of this compilation, data for 618 unaltered samples and 549 altered samples were identified and included in this data release as Appendix 2, the Microsoft Excel file 'DS1080_appendix2_SE_MO_ChemData.xlsx,' and its derivative ASCII tab-delimited text files 'DS1080_appendix2SE_MO_ChemData_FreshUnaltered.txt' and 'DS1080_appendix2_SE_MO_ChemData_AlteredMineralized.txt'. Data sources, including published reports and theses, are itemized and tabulated in the Data_Src field in Appendix 2. Along with the data found in Day and Granitto, 2014; Day, Granitto, and others, 2016, and Granitto and others, 2017, this compilation process has likely resulted in the identification and incorporation of the majority of compositional data available for Mesoproterozoic igneous rocks in the St. Francois Mountains, Missouri. Compiling analytical methods and associated estimates of precision and accuracy associated with previously published data is beyond the scope of this effort. Analytical protocols, precision, and accuracy were highly variable among the previous publication sources. Fortunately, most publications document these parameters and details can be retrieved by referring to the original publication identified in the Data_Src field.

This data release includes whole rock (WR) geochemical data for 94 samples. Whole rock geochemistry data were analyzed at Actlabs in Ancaster, Ontario, Canada. Rock samples were collected by Peter Valley, Greg Walsh, Arthur Merschat, and Ryan McAleer. The whole rock geochemistry data characterize the composition of mapped meta-igneous rocks in eastern Vermont and western New Hampshire, USA. The data release contains three files, including one metadata file and 2 comma-delimited (CSV) files. The CSV files include the following: BronsonHill_WR_data.csv and BronsonHill_WR_data_dictionary.csv.

The Dinwiddie terrane, formerly the Petersburg Granite (sensu lato), was originally interpreted as a Pennsylvanian - Permian igneous complex located in the eastern Piedmont of Virginia and considered to be a single batholith that comprises different textural varieties, likely assumed to have been emplaced from a single source during Alleghanian metamorphism (Bloomer 1939; Bobyarchick, 1978; Bobyarchick and Glover, 1979). However, mapping in the 2000s and 2010s (Carter and others, 2007; 2010; Carter, 2010; Bleick and others, 2011; Bondurant and others, 2011; Occhi and others, 2015, 2017; Occhi and Swanger, 2019) divided this into five distinct units based on lithology, including a subidiomorphic granite, a porphyritic granite, a foliated granite, a layered granite gneiss, and a megacrystic granite. Though these varieties of granite and gneiss were originally considered to be part of the same unit, Carter and others (2023) evaluated each of these five lithologies on the bases of their geochemistry and geochronology, and determined that the foliated granite and layered granite gneiss are ~100 million years older than the other lithologies and that they record evidence of a different magma source than the subidiomorphic granite, porphyritic granite, and megacrystic granite, prompting the redefinition of the Petersburg Granite (sensu lato) into the Dinwiddie terrane, which encompasses the entire suite of granites and gneisses formerly referred to as the Petersburg Granite (sensu lato). The Dinwiddie terrane can then be divided into the Petersburg Granite (sensu stricto), which is composed of the subidiomorphic granite, porphyritic granite, and megacrystic granite lithologies, and the informal Pocoshock Creek Gneiss, which is composed of the foliated granite and layered granite gneiss. Despite this redefinition, their work did not establish the Pocoshock Creek Gneiss as a formal lithodemic unit per the North American Commission on Stratigraphic Nomenclature (2021). Therefore, in order to better characterize the Pocoshock Creek Gneiss, justify its division from the Petersburg Granite (sensu stricto), and define this unit formally, geochemical data from these two units are compared. This data release comprises unpublished geochemical data collected during the work of Carter and others (2023), as well as a compilation of published geochemical data from Carter and others (2023) and from various igneous intrusions throughout the southern Appalachians for comparison with the Petersburg Granite (sensu stricto) and Pocoshock Creek Gneiss. The sources of all geochemical data included in this data release are described further within this metadata.
