All the volcanic rocks present younger K-Ar age (less than 5Ma), which can be termed as Cenozoic rocks. In general speaking, volcansim can be dividied into two eruptive stages. In the first stage, volcanic rocks for Pliocene epoch (4. 4-5Ma) consist of basanite and tephrite, which distributed on Mt. Crater, Cape Bird, and southern bank of Bonney Lake; In the second stage, volcanic rocks for Quaternary (less than 1 Ma) are mainly composed of latite, which are distributed on Cape Rodeys and Cape Evens.On the basis of geochemical data such as major elements, trace elements , rare earth elements, isotope, microprobe analysis, combined with main achievement taken by previous researcher in this area, conclusions are drawn basically as follows

The determined thermal conductivity values vary from 0882 to 678 W/m?K and the calculated heat flow values in Jianghan Basin range from 419 to 609 mW/m2,with a average of 523 mW/m2.It shows that the influence of tectonothermal event before Cenozoic in Jianghan Basin has faded away,and the basin has cooled down.

In existing ich-nofacies model trace-making courses with ulti-stages and ulti-tiering are not stressed. Existing ichno-tiering models are based mainly on the Mesozoic-Cenozoic data. The reported data show that tiering distributions of Chondrites are different in Palaeozoic and Mesozoic-Cenozoic.

流行的遗迹相和遗迹阶层模式的不足是：前者在操作上，简单地将遗迹化石及其组合处理为同沉积或准同沉积的物理沉积构造，忽略了造迹活动的多阶段和多阶层的特点；后者的资料基础仅依据中生代以来的地层记录，对重大生物-环境事件和造迹生物生态习性演化对遗迹阶层形成和分布的影响注重不够。
