Researches in paleovolcanic geology and metallogeny to Zheyaoshan Cu-Zn deposit area of Baiyin Ore-field suggest that the area is a large paleovolcanic crater well-developed with a suite of erupted,erupt-flooded and flooded phases,volcanic stump,subvolcanic intrusions and extrusives as well as erupt-sedemantary phases.

古火山地质学和矿床学研究表明，白银矿田折腰山Ｃｕ－Ｚｎ矿床地段，是一个火山岩岩相发育齐全（包括喷发－爆发相、喷发－溢流相、溢流相、火山颈相、次火山侵入相、火山侵出相以及喷发－沉积相）、空间展布有序、相序关系清楚的大型古火山口。

冲绳海槽位于中国东海大陆架的东部,与东海陆架相连,是一个新生的孤后盆地,海底火山活动和地震频繁,断裂体系十分发育,沉积了十分丰富的火山碎屑沉积物,根据海底沉积物中的浮岩与磁铁矿含量变化,结合水深资料推测了海底火山口的位置,结果表明Z 14—5测站(27°18′N、127°12′E)附近是一个火山口。
