Spilite-keratophyre sequence is generally divided into spilite, keratophyre and quartz keratophyre.

Finally, it can be concluded for the first time that there was a large time gap between diagentic process of the volcanic rocks related to the Dapingzhang VHMS deposit and the ore-forming process, then a ore-forming model of the Dapingzhang deposit can be made, that is, the deposit passed through two important stages: the ore-forming metals concentrated during formation of the Early Palaeozoic spilite-quartz keratophyre on the island-arc belt, and the mineralization caused by the Late Palaeozoic magmation.
