In large-scale gradient studies, selection of the best research sites is critical but time-consuming and costly. Multivariate methods can be used to quickly identify suitable sites from existing data bases. Based on a study of acid deposition in the Great Lakes region (the Michigan Gradient Study), we illustrate the use of multivariate methods in screening potential research sites for similarity. Sites were examined using cluster analysis, principal coordinates analysis, and correspondence analysis. The graphical displays generated by the multivariate methods were used to identify similar sites across the gradient. A list of 31 potential sites was reduced to 5 similar research sites and several alternative sites. The results of the multivariate methods compared well with more traditional methods of research site selection but allowed for multiple comparisons of many potential sites using a variety of data from existing data bases. By eliminating sites that are unacceptable with respect to available data, the multivariate methods reduce the number of sites that require field visitation prior to final site verification. This process represents a substantial savings in time and effort when dealing with a long list of potential research sites.

There are many ancient underground quarries in Zhejiang Province, China. Many caverns of them maintained steady more than 1000 years. Certain engineering geological condition is very important for long-term stability. In this paper, ancient underground quarries in Shepan Island are presented as a case. Shepan Island ancient large-scale underground quarry caverns are located in Sanmen County, Zhejiang Province. These caverns were excavated more than 800 years ago and at least 1300 of them are reserved until now. Shepan Island is a hill which uplifts the continental shelf extending to the gulf. There are no large regional fractures through caverns area, which indicates that it belongs to earthquake stability region. The caverns were excavated in thick volcanic clastic rock formed in the upper Jurassic, with NW and NE faults and NW joints. Based on the study of rock weathering, physical and mechanical tests of rock samples, and inverse analysis of structural plane, the huge thick volcano clastic rock can be classified as block structure. In addition, groundwater which affects the stability of caverns was analyzed based on the investigations of hydrogeological conditions. Site selection of ancient large-scale underground quarries is query scientific from modern engineering geology point of view.
