华南古海洋热水沉积作用研究概述及若干认识

Thread and Knowledge to Fossil Sea-Floor Hydrothermal Sedimentation of South China

华南地区热水沉积建造发育 ,在沉积建造类型、沉积作用方式、产出的大地构造背景及岩石地球化学特征等方面反映了热水沉积的多样性。该地区的热水沉积作用具有相对确定的演化特性 ,并与许多金属矿床有直接或间接的关系。

WT5BZ]Fossil sea floor hydrothermal sedimentary formations developed well in South China, such facts has attracted attention from Chinese scholars since 1980s. The hydrothermal sedimentation varied in sediment formation, model and tectonic background as well as in geochemical characteristics. It had certain evolution direction, and was to various extents in relation to the formation of many metallic ore deposits in this area.
