The sedimentary environment and genesis of Middle Ordovician nodular limestones in Keping,Xinjiang;

Geochemistry of Salgan Black Shales of Middle-Upper Ordovician in Keping Outcrop, Tarim Basin;

Based on geological background, the author suggested that giant oil and gas fields formed during the second reservoir formation cycle and not destroyed can be found in Keping covered structural region.

The Dawangou section of Kalpin area, Xinjiang and Guangzhuang section of Pingliang area, Gansu were proposed as the global stratotype for the base of the Nemagraptus gracilis Biozone and the base of the global Upper Ordovician Series.

Located on the northwest margin of the Tarim basin,the Kalpin Ranges are totally composed of thrust sheets, which comprise from Cambrian to Permian stata generally dipping to north.

Sedimentary sequences in Keping area, Xinjiang: Constraints from carbon and oxygen isotope compositions of Cambrian to Ordovician carbonate rocks

The source rocks in Keping area of Tarim basin are studied synthetically and qualitatively by combining the previous findings with the analytical data of samples from drilling cores and the section outcrops.

Based on the study of Silurian outcrop at the Kalpin area in the northwest of Tarim Basin, Xinjiang, 15 ichnogenus and 28 ichnospecies, namely, Asterichnus lawrencensis, Cochlichnus anguineus, Cruziana ichnosp.

Based on the study of the Silurian sections in the Kalpin area of the northwestern Tarim Basin, eight ichnogenus and eight ichnospecies were recognized in the Lower Silurian Tataaiertage Formation.

Hydrological Feature and Flood Analysis in Keping River on South Slope of Tianshan Mountains,Xinjiang;

The Kalpintag nappe is located at the southwestern foot of the Tianshan Mountains,consisting of several rows of NE-to EW-trending fold-reverse fault zones.

Based on a lot of outcrop geological surveys, we discussed the thrust fault belt in the front of the east section of Kalpintag in Kalpin area and found many evidences, including the fault incising the surface of diluvium and fluvial channel sediments and terraces, and also the fracture and subsection character of the faults.

This paper tries to discuss paleoearthuakes along the east section of the range front fault of Kalpintag during late Quaternary by doing field investigation along the fault, measuring geomorphic deformation and excavating trenches in some important sites where young alluvial fans were displaced obviously.
