Our investigation shows that neither the dioritic porphyry nor the sedimentary rock is the source of iron ores, and that the source of most ironrich orebodies is the ore magmahydrothermal system in the deep chamber. Ore magma which was formed by liquid immiscibility is the main source of Gushan deposit, and the residual ironrich hydrothermal fluids which occurred as NaFeCl complex is the main source of Baixiangshan deposit.

根据野外观察和地球化学研究，文中认为，闪长玢岩岩体和沉积围岩均不是铁质的主要来源，富铁矿体的成因主要来自矿田深部的矿浆热液系统，姑山式铁矿的铁质主要是液态不混溶作用形成的铁矿浆，白象山式铁矿的铁质主要来源于深部残浆分离出的NaFeCl络合物。

As open a source to warm up in global abidance, there also are more and more people to never had known a cause in China, use Linux to the attempt, development becomes the lover of the source, champion, the opportunity that meets through meeting this, they experience the intendment of the source more deep-feltly, experience the glamour of the source.

Furthermore, the theory foundation and analysis method are put forward. We use optical extent to analyze the system. The change of optical extent, caused by arc length of light source and reflective bowl attached the light source, is analyzed in detail. Moreover, the light output by optical extent curve of light source with reflector is measured by experiment. Base on the analysis and experiment, four hypothesis are put forward to construct the true model of light source.

Maturity of Lower Cretaceous source rock, researched by the authors, is closely relative to the deposition thickness of the Tertiary and the Quaternary. It shows that source rock at the depth of 4,000-4,400m is low mature, and 4,400-5,200m is in the peak of oil generating. Correspondingly, the source rock of the Zhonggou Formation is immature; the Upper Xiagou Formation is low mature; and the Lower Xiagou Formation and the Upper Chijinpu Formation are in the peak of oil-generating; and the Lower Chijinpu Formation is at the stage of generation of condensate-wet gas with high maturity. There is no source rock reaching the overmature stage of dry gas at present.

可溶有机质转化率、镜质体反射率、热解、生物标志物特征等参数表明：青南凹陷中部的下白垩统烃源岩生油门限深度为4000m（相应的镜质体反射率为0.65％），埋深4000～4400m为低成熟阶段，埋深4400～5200m为成熟生油高峰阶段，因此中沟组烃源岩未成熟，下沟组上部烃源岩低成熟，下沟组下部和赤金堡组上部烃源岩处于成熟生油高峰阶段，赤金堡组下部烃源岩处于高成熟的凝析油—湿气阶段，目前尚无烃源岩达过成熟干气阶段。
