New discovery of Late Cretaceous tyrannosaurid tooth from the Heyuan basin,Guangdong Province,Southern China

Red beds in the Heyuan Basin reach as much as 5 000m thick, and are divisible in ascending order into the Dafeng, Zhutian, Zhenshui, Danxia and Xinzhuangcun Formations based on lithologies.

Study on the Features of Magnetic Field and the Sedimentary Structure in Mohe Basin;

Provenance Analysis of Middle Jurassic Sediments and Its Geological Significance in Mohe Basin;

Tectonic Characteristics and Basin Evolution of the Mohe Basin, Heilongjiang Province;

Characteristics of Sporopollen Assemblage and Its Palaeoclimate during Quaternary Pleistocene in the Huhe Sag,Hetao Basin;

Charater of seismicity before the Ms≥5.5 earthquakes in Hetao basin;

Research about Geological Conditions of Shallow Gas (Biogenic Gas) Accumulation in HETAO Basin;

Characters of coal classification and coal rank distribution in third member of Shahejie Formation in eastern depression of Liaohe basin;

Lithologic identification and reservoir division of Xing-Ma Archean group buried hill in Liaohe basin;

Research on hydrocarbon abundance conditions in nearshore sublacustrine fan in Western sag of Liaohe Basin——take Rehetai Formation in Xing-Bei area as an example;

Oil-oil meticulous correlation research shows that there exist both immature and mature oils in Oulituozi area of the Liaohe Basin,and the maturity level of these oils is generally lower than those in the other areas of the East Sag.

According to analysis of formation water and crude oil at the west Jinganpu of Damintun Sag in the Liaohe Basin,type NaHCO_3 formation water on the top of the burial hills in the studied area is dominative,type CaCl_2 appear in local area.

In order to understand the control of hydrogeological conditions on accumulation of coalbed methane in low rank coal,a comparison study is carried out between the Powder River basin in America and the Juggar basin in China.
