Aimed at the Dur'ngoi hydrothermal Cu-Co deposit, Qinghai, a study of regional geochemical characteristics and regional geochemical anomalous characteristics has been made in the paper.

Based on the basical features of seismic background, temporal and spatial distribution of seismicity and precursory earthquake swarm activity, this paper discussed the anomalous characteristics of seismic activity before Gonghe earthquake.

Short-impending anomaly characteristics on a series of M6-2Ninglan earthquakes,1998;

Anomaly characteristics of the earthquakes with M s6.

Heavy metal contents in top soils in agricultural soils of Zhejiang province and their differential characteristics and effecting factors were studied in the presented paper through field soil investigation.

Anomaly characteristics of subsurface fluid in Tianjin region before Wen′an earthquake with M_S5.1;

The authors briefly introduced the operating principle of GPR and its method and technique for investigating the subterranean cavitation,with some subterranean cavitation inspection of groundwork exploration in Guangzhou as an example,analyzed the radar wave group characteristics of subterranean cavitation,and summarized the anomaly characteristics of the time-depth sections of the GPR.

Based on anomaly characteristics as well as geological and remote sensing data,the authors have distinguished false anomalies from real ones,thus providing a theoretical basis for further exploration arrangement.
