在广西1：25万南宁市等四幅区调工作中，发现上二叠统彭久组与下伏中二叠统板城组为整合接触，属东吴运动时台间海槽中的低水位沉积；证实都安组（C1d）与融县组（D3r）为平行不整合，期间缺失杜内期沉积；建立了测区法门期有孔虫带。查明了六万大山．十万大山岩带酸性侵入岩与火山岩的成因联系及其活动序次，新发现二条韧性剪切带和推覆构造，为阐明钦防地块的构造属性和演化提供了新资料。
在廣西1：25萬南寧市等四幅區調工作中，髮現上二疊統彭久組與下伏中二疊統闆城組為整閤接觸，屬東吳運動時檯間海槽中的低水位沉積；證實都安組（C1d）與融縣組（D3r）為平行不整閤，期間缺失杜內期沉積；建立瞭測區法門期有孔蟲帶。查明瞭六萬大山．十萬大山巖帶痠性侵入巖與火山巖的成因聯繫及其活動序次，新髮現二條韌性剪切帶和推覆構造，為闡明欽防地塊的構造屬性和縯化提供瞭新資料。

Conformable contact between Upper Permian Pengjiu Formation and underlying Middle Permian Bancheng Formation, both of which belongs to low water level sedimentary during Soochow movement, is found in 1：250 000 Nanning City and adjacent area, Guangxi province. The accordant unconformity between Du＇an Formation （Cld） and Rongxian Formation （D3r）, during which lost the Tournaisian sedimentary, is conformed, and Famennian foraminifera zones of studying area are established. The genesis and activity sequence of magrnatic rocks from Liuwandashan-Shiwandashan belt are studied in detail, and new ductile shear zone and nappe structures are discovered, and those information are provide useful data for clarify the tectonic feature and evolution history of Qingzhou-Fangcheng block.
