CraterRimDikeData.xlsx

Field and petrographic observations for dikes observed throughout Akaroa volcano, including Akaroa Harbor and Akaroa's crater rim. Portions of the tables included in this spreadsheet are included in the ArcMap file Akaroa_JGR_map.mxd. Tabs are organized as follows:<br>Akaroa_2010_dikes: comprehensive list of field coordinate and strike or trend observations for 643 dikes found throughout Akaroa Volcano made in the year 2010. Coordinates are reported in New Zealand Map Grid, part of the New Zealand Geo-datum 1949.<br>Gaddis_2014_dike_catalog: Akaroa dike data curated by former University of Canterbury Frontiers Abroad student Emily Gaddis, whose semester research project investigated dome and dike formation on Akaroa's crater rim and served as a foundation for the research of Goldman et al. (in prep).<br>48 trachyte: collated subsets of Akaroa_2010_dikes and Gaddis_2014_dike_catalog containing trachyte dikes found along Akaroa's crater rim. These dikes are displayed in the ArcMap file Akaroa_JGR_map.mxd and Figure 1 of Goldman et al. (in prep).<br>32 basalt: collated subsets of Akaroa_2010_dikes and Gaddis_2014_dike_catalog containing basalt dikes found along Akaroa's crater rim. This sheet also contains four dikes observed by students of the University of Canterbury's Frontiers Abroad Program in 2013 and 2014. These dikes are displayed in the ArcMap file Akaroa_JGR_map.mxd and Figure 1 of Goldman et al. (in prep).<br>Crater Rim dikes collated: list of all 86 crater rim dikes reported in Goldman et al. (in prep), including ArcMap shapefile name (c.f., Akaroa_JGR_map.mxd), the radial distance from the center of Akaroa Harbor to each dike (calculated using the "near dist" function in ArcMap), the elevation for each dike, and the corresponding z-coordinate in the COMSOL model of Akaroa Volcano of Goldman et al. (in prep) that defines z = 0 as 1200 m below sea level.<br>BLE_Figure5_dikes: plot of crater rim dikes presented in Figure 5 of Goldman et al. (in prep), as well as the basis for the Purple Peak and Panama Rock dike locations displayed in Figures 6-8. The two individual Purple Peak dike locations reported in the tab "Crater Rim dikes collated" are replaced by a single point representing the central field location for both dikes (c.f., Waypoint 345, Table S5 of Goldman et al.).<br>
