The Tianchi forming cone eruptive magmatic evolutionary series of the Chanbaishan and stratigraphic division
On the basis of the lithological features of the Tianchi volcanic rocks, chemical compositions and mode of occurrence, the volcanic forming cone eruption can be divided into four stages, and each eruptive characteristic and evolutionary regularity are described at the same time. The magmatic evolutionary can be devided into two cycles, the characteristic and lithological feature of each cycle were described, last, we mad a stratigraphic division and stratigraphic correlation with the adjacent strata.
