According to the vertical distribution of the bivalve within Erqiao formation in northwest Guizhou and its adjacent areas, two assemblages of bivalve may be sorted, namely the upper Indosinion-Permophorus assemblage and the lower Qiyangia-Hunanella assemblage.

This paper sums up the geological features of the Pb-Zn deposits in Qiziqiao formation in Dongpo area of Chenzhou.

Silicalite is found in the strata of the first and third members of Dashiqiao formation,Liaohe group in Xiaogushan area, Liaoning Provinece, where a series of nonferrous and precious metallic mineral resources are distributed.

The analysis method of this paper can be referenced for other composite arch bridge.

A pedestrian bridge in a residence quarter in Huzhou is designed to be a composite arch bridge, with 2 bearing arches and 1 tension arch, asymmetrical as a whole.

The main shipping channel bridge and the non-navigable span approach bridges of the Bridge respectively make use of the long span continuous composite arch bridges and continuous composite box girder bridges that are all erected by the multi-point and synchro incremental launching construction technique.
