Hydrothermal chimneys with tubular shape were formed in the process of hydrothermal fluids eruption at sea-floor. Their structure and chemical composition are closely related to properties of hydrothermal fluid. There exist great geochemical gradient, thermal gra- dient and mineral assemblage gradient across 1―3- cm-thick wall of chimneys, which includes abundant information of hydrothermal fluid properties and for-mation temperature and also records the growth pro- cess and history of chimne… 相似文献
