Farming culture is the main part of Chinese outstanding traditional culture and also the important spiritual and cultural resources to construct the core values of the Chinese nation. In the new era, fully exploring and making full use of farming culture resources has important practical significance for the protection, inheritance and innovation of Chinese excellent traditional culture. The rapid development and successful brand shaping of Hani terrace tourism could provide experience for the exploration and utilization of farming culture tourism resources in other areas of China. Based on the analysis of development process of Hani terrace tourism as well as the successful experience of other regions for reference, ideas of developing farming culture tourism in the dabie mountains were proposed.

Four generations of mineral assemblages have been identified in ultrahigh-pressure (UHP) eclogites from the Hong’an area,recording four metamorphic stages of the exhumation trajectory,i.e.,garnet+omphacite+kyanite+ zoisite/epidote+rutile+coesite formed at the UHP stage,garnet+omphacite+paragonite+phengite+amphibole+epidote+quartz at the high-pressure (HP) eclogitic stage,amphibole+epidote+albite-oligoclase+paragonite+quartz at the epidote-amphibolite facies(EA) stage,and actinolite+ albite and pumpellyite+albite+K-feldspar+muscovite+chlorite+margarite+epidote+quartz at the greenschist facies(GS) *** formed at the UHP stage was overgrown by atoll garnet at the HP stage. X-ray images,mineral compositions and compositional profiles indicate that the UHP garnet experienced a variable Fe-Mg modification in response to Fe-Mg exchange between garnet and omphacite prior to the overgrowth of atoll HP garnet.A volume diffusion zone was also observed between the UHP and HP *** following P-T conditions were estimated for these mineral assemblages:480 to 560℃and 2.5 to 2.9 GPa with median values of 520℃and 2.8 GPa at UHP stage,575 to 685℃and 1.6 to 1.9 GPa with the average results of 634±37℃and 1.8±0.06 GPa at the HP stage,500 to 640℃and 0.4 to 1 GPa at the EA stage,and 160 to 320℃and 0.2 to 0.8 GPa at the GS *** Hong’an UHP eclogites experienced a temperature increase of over 100℃from the UHP to HP stages and continued to exhume from the HP to EA stages through a process of approximately isothermal depression,which was followed by a significantly cooling from the EA to GS *** the process of exhumation,UHP eclogites witnessed a series of events involving fluid influx,resulting in the formation of hydrous minerals at different stages. The nature of fluids changed from K-rich at the HP stage to K-poor at the EA stage and then K-rich again at the GS stage.
