OneDZ: A Global Detrital Zircon Database and Implications for Constructing Giant Geoscience Database

This is the new, version 3 of the OneDZ database. Following the reviewers' comments, the new version adopted the "key-value" framework to manage the whole database to improve the searching efficiency. The calculated uncertainties and estimated coordinates has been noted in the "zircon_id". This design is to decrease additional sparse searching cost. The calculatations and estimation would not effect the statistical results after testing. For takeaway users, just apply the database directly. If you are not familiar with MySQL, we recommend you to find data from csv files. This new version added some new data from remote contribution by the web platform of OneDZ. In the next published new version (include this), csv files would not be published because of data were stored by "key-value" structure. Sorry for this, but transfferring the structured MySQL file to the unstructured csv files is really time-consuming.
