Abstract

Abstract

To understand the distributions of the temperature and flow fields within the large hydrothermal sulfide deposit is important to study the formation and mineralization processes of seafloor hydrothermal deposits. Based on the results of ocean deep program (ODP), a hydrothermal deposit model with 3-layer is set up, and the distributions of the thermal and current fields under different permeability conditions are simulated using the Hydrothremal software, which is developed by U.S. Geological Survey (USGS). The results indicate that (1) in the homogenous model, the increase of Rayleigh number can cause the temperature decrease and the fluid flow faster; (2) heterogenic structures within the deposit have great influence on the distribution of the temperature fields; (3) the distributions of black smokers in mature deposit are related to many factors, such as heat source and permeability.
- seafloor hydrothermal activity,
- hydrothermal sulfide deposit,
- thermal field and current field,
