The results showed that 2nd episode of Zhu-Qiong movement was an important tectonic transformation that occurred during rifting, basin structure patterns above and below the regional angular unconformity caused by 2nd episode had distinct differences. The orientations of those basin-controlling faults changed from NE, NEE to EW, NWW, which indicated that the paleo-stress field veered from NNW extension clockwise to sub-NS extension and basin structures patterns transformed from NE, NEE strong rifting to sub-EW, NWW weak rifting. The depocenter showed seesaw-like migration from S to N. And the sedimentary systems transformed from semi-deep-deep lacustrine facies to braided river delta facies developed in shore-shallow lacustrine. Combined with its tectonic recombination of periphery plates that period, the mechanism of above tectonic transformation had direct correspondence to the readjustment of the Indian plate and the Pacific plate. The southward subduction of the pro-to-south China Sea is the direct cause of this tectonic transformation. </div>展开更多

The study is based on analysis of personal counseling experience, where literature was used as a tool to disclose client＇s personal meanings. During our sessions, clients were observed phenomenologically, and their speach was written down. Reflecting on the qualitative data of transformative learning in language arts, we developed techniques for facilitation and disclosure of personal meanings. Grounded theory was used for data generalization： Personal educational insights and its comparison with other researchers＇ theoretical insights were the basis to develop the methodical system for psychological guidance and counseling and to explain it. We revealed that focus on personally important meanings during discussion after literature reading has influence on the mental state of personality and deepens the interactions with the literature art, so we suggest a spiral model to explain the methodical system of our method. Transformative learning in language arts as a method of guidance and counseling can be understood as spiritual motion by spirale. It has three levels： （1） art level （interaction with the literature）; （2） psychology level （counseling）; and （3） art level （interaction with the same peace of literature as in the beginning of the session, poetic summary of the session）. Levels （1） and （3） mean interaction with literature art, but at the third level, this interaction has new quality, because personality has better perception of Self and more ability to connect personal meanings and literature wisdom. At the first level, we have direction from literature to Personality. At the third level, we have direction from the Self （Speaking from Within） to literature. Disclosure of personally important meanings is a key to self-understanding and poetical thinking; our developed methodical system reduces emotional tension and strengthens interconnectedness between inner and outer world and improves poetical understanding. In this paper, the methodical system of transformative learning and guidance is discussed.展开更多
