Geochemical constraints on the tectonic setting of the Proterozoic turbidites in the Xuefeng Uplift region of the Jiangnan orogenic belt;

Based on the geological survey,balanced cross-section analysis and regional tectonic evolution,we take advantage of rock acoustic emission information to restore the maximum paleo-stress in the southwest margin of Xuefeng Uplift,and discuss the relationship between the maximum paleo-stress and hydrocarbon accumulation and damage.

According to the planar distribution of the strata,fold and fault,field observation and interpretation of seismic profiles,the constraints of Paleozoic normal faults on structural characteristics are studied,combined with the thrust of Xuefeng Uplift.
