Abstract: |
This dataset contains a list of volcanoes, and for each volcano, a list of 5 major and minor rocks, per material (WR = whole rock, GL = volcanic glass, INC = inclusion, all = whole rock + volcanic glass + inclusion), with percentages. <br> A rock is called minor if its percentage is < 10% <br>. Only samples for which FEOT>0, NA2O>0, K2O>0, and 35 < SIO2 < 80 are considered. <br> Rock names are given according to two terminologies: according to the TAS classification (first csv), and according to GVP classification (2nd csv). These datasets were computed using the data from GEOROC (2021), also available in this dataverse, including the manual datasets for Fuji, Merapi and Rinjani. <br> If a sample has two materials (e.g. WR/GL), then by convention we chose the first material. <br> If two rocks have the same percentage, no convention is used to rank them, they are ranked arbitrarily. <br> The dataset uploaded on Dec 19 improves on the previous datasets by separating major and minor rocks, and by giving the percentages. The dataset uploaded on March 20 2023 normalizes by the main oxides instead of normalizing by all oxides. |
