Back folds in the core of the Himalayan orogen: an alternative interpretation
Article Abstract:
The hanging wall of the South Tibetan detachment system was originally thought to be caused by gravity, as characterized by its regional-scale, northeast-verging folds. Recent studies have offered a different interpretation of the movement and suggests a fan-structure occurrence which was estimated to have happened sometime between the late Eocene to Oligocene stratigraphic geological period. A new model for studying the northeast verging folds of the Kali Gandaki is proposed.

Occurrence, age, and implications of the Yagan-Onch Hayrhan metamorphic core complex, southern Mongolia
Article Abstract:
The Yagan-Onch Hayrhan core complex is an important geological reference point for the study of the tectonic evolution of Asia. Tectonic movement in this area indicate a subhorizontal south-southeast directed extension, which became largely prominent during the early Cretaceous period. High-strain extensions, which were recently recognized in certain parts of eastern Asia, were believed to have occurred in southern Mongolia.

Carbon-isotope composition of lower Cretacious fossil wood: ocean-atmosphere chemistry and relation to sea-level change
Article Abstract:
Fluctuations in the isotopic composition of CO2 in the global ocean atmosphere system were the main influence in the formation of the stratigraphic signature of the time-dependent carbon-isotope fossil wood fragments. Excursions through the lower Aptian reveals climatic relationships consistent with the simultaneous development of the carbon-isotope fossils and ocean floor sediments.
