摘要
A crust data analysis device (1) is provided with: an acquisition unit (41) for acquiring a plurality of data items indicating the crustal abundance of a prescribed element or compound at a plurality of locations; a generation unit (42) for using differing first thresholds to delete, from the plurality of data items, data for which the crustal abundance is greater than or equal to the first threshold corresponding to the data item and generating a plurality of data items for which deletion has been completed; a determination unit (43) for determining whether the data composing the data items for which deletion has been completed conforms to a normal distribution having the average crustal abundance of the prescribed element or compound within an area larger than the area including the plurality of positions as the mean thereof; and a setting unit (44) for setting a geochemical anomaly threshold to the maximum crustal abundance value in the data item for which deletion has been completed having the smallest amount of data from among the plurality of data items for which deletion has been completed that have been determined to not conform to the normal distribution.
