Lying in the North margin of the middle section of Nanling metallogenic belt and at the outer part of the contact zone betweem Qianlishan Granite and the limestone,Jinchuantang deposit is a skarn Sn-Bi deposit,occurring in strata of the Middle-Upper Devonian systern and being controlled by structure,rock feature and magamatic activity all together.

Directly Pouring the Sn-Bi Alloy Pattern or Press Die by Using a Prototype Made of Paper;

The process of acidic Sn-Bi alloy electroplating was developed by Hull cell tests.

Semisolid Sn-Bi alloy slurry can be obtained by mechnical stirring technology.

Study of solderable lead free tin-bismuth alloy electrodeposition;

Discovery of diarite at the depth of the Dajing tin polymetallic deposit and its significance for exploration;

Tin polymetallic deposit in Changpo district are located in west ore zone of Dachang tin polymetallic ore field,which is formed under the integrated function of strata,fractures and magmatic rocks,namely stratum is the basic condition while structure played ore conducting function and the magma provided heat source and possible ore liquid or matter.

Fluid inclusion studies of Longshang tin-polymetallic deposit in Xitian ore field,eastern Hunan Province;

~(40)Ar/~(39)Ar isotopic dating of the Longshang tin-polymetallic deposit, Xitian orefield, eastern Hunan;

Based on the spatial analytical module of MAPGIS system, this paper tries to carry out the statistical analysis of a large regional spatial data, and statistically analyses some properties of the related objects including favorable ore-forming strata, structure, magmatic rock and the distribution trend of tin-polymetallic deposits in South China.
