This is one of the series publications ''The Lithofacies
and Palaeogeography and Prediction of Sediment-hosted Mineral Deposits
in South China'', an research program set by Ministry of Geology and Mineral
Resources. More than 300 researchers and 30 Institute and Organizations
have attended in this huge projects. The general programme is a systematic
summary and theoretical refinement of all research in this project. The
publication of those achievements is of great significance in the researches
of lithofacies-palaeogeography and depositional mineralization in China.
This research is of considerable significance because
it provides the following important characters.
1. Judging from the academic guiding thought. it assimulated the advanced
theories of sedimentology and the view point of ''mobilism'' of global
tectonics, with the attempt of analyzing the geological evolution of South
China based on the tectonic setting of global sedimentary crust evolution
as a whole.
2. It makes the best use of the latest data on sedimentary facies in South
China. Taking continental margin as the focal point, it systematically
analyzed the sedimentary environments and their evolution of each geological
period and made a preliminary research into sequence stratigraphy and
sea level changes which is of considerable significance in the development
of sedimentary palaeogeography and stratigraphy.
3. It Places emphasis on the correct viewpoint that the formation of basin
was controlled by tecton-ism and that the sedimentation was controlled
by the feature of basin. The authors not only reviewed and analyzed the
tectonism of the basement in the geological history of South China, but
also pay much attention to the tectonic function and tectonic subsidence
when they made scientific analysis of a basin. Based on the above-mentioned
viewpoint, a valuable suggestion of dividing the tectonism of South China
into several developmental stages was put forward.
4. Adhere to the orientation of research, the authors persist the right
way of combining basic geology with applied geology, and suggested that
the mineralization of sediment-hosted mineral deposits was closely related
to the effects and interaction among sedimentary evolution of a basin,
tectonic development and geologic events. Their work, not only discussed
the enrichment processes of various useful elements associated with various
geological events, but also promoted mineralization domains and mineralization
zones concretely. All these provide scientific evidences for ore exploration
in the future.
5. So far as the organization and efficiency of this project are concerned,
it is a complex system program, whose participators include several tens
of institutions and several hundreds of workers.
In the course of research, not only the initiative and concentrated wisdom
of the researchers was brought into full play, but also various discussions
and academic exchanges were organized.
