 The Zircon UPB chronology database provides a good opportunity to obtain important Zircon growth peak periods in Earth's history, but research preference affects the objectivity of Zircon sampling, leading to hot data in the database and age statistics. To evaluate the influence of hot data on statistical results, the W and Y indexes are introduced. Using a Gaussian model of multi-peak fitting of Zircon UPB age frequencies, we identify seven major growth peaks in Zircons from the Chinese continental crust, which can be divided into two categories based on time scales. These ages correspond to various geological events recognized by most scholars. This article was authored by Yu Jingwu, Zhe'an Junfang, Cixi Liao, and others.
