我参与了在土耳其（2009年）、阿曼（2010年）、克什米尔（印度，2014年）和亚美尼亚（2017年）举办的IGCP 572实地研讨会，以及随后的IGCP 630实地研讨会，为每一个研讨会共同编写了详细的指南和详细的报告，这些报告可以在ResearchGate网站上找到和下载。本文总结了IGCP 572和630成员在过去10年中在这四个重要的野外工作地点所获得的最终成果，并试图对今后基于特提斯洋周围这些独特地点的研究提出建议。在安塔利亚大学Erdal Kosun博士的后勤支持下，2009年9月在土耳其南部举办了第一次国际地质对比计划572实地研讨会。在土耳其南部野外研讨会之后，发表了8篇重要论文，涉及保存完好的二叠纪-三叠纪界线（PTB）微生物岩及其生态系统（包括介形类，腕足类和许多其他分支）。2010年2月在阿曼苏丹国举行了第三届国际地球科学计划第572年度实地研讨会，Michaela Bernecker博士和位于麝香的GuTech大学提供了大力支持。超过15篇论文来自IGCP 572成员在本次研讨会期间调查的P-Tr序列，包括第一份基于硼同位素的海洋酸化研究。新的古生物学研究仍在进行中，涉及Smithian菊石，下三叠世鲨鱼牙齿和牙齿遗骸以及基底三叠纪牙形刺，海百合和菊石。在查谟大学Ghulam Bhat教授的大力协助下，第一届IGCP 630年度实地研讨会于2014年11月在印度北部克什米尔的斯利那加举行。这次会议更新了对该地区经典Guryul Ravine和邻近P-Tr边界剖面的研究，对碳同位素和黄铁矿framboids进行了新的地球化学工作，并进行了详细的印度牙形石分类和分带。其他新的古生物学作品关注Guryul Ravine部分的孢粉学，因为一些保存完好的有机真核原生生物（thecamoebians）穿越PTB而不破坏PTB。Lilit Sahakyan、Aymon Baud和Zhong-Qiang Chen于2017年10月8-14日在亚美尼亚组织了第五届IGCP 630年度会议和现场研讨会。对几个PTB和下三叠统剖面进行了系统的地球化学和地球生物学研究。这些亚美尼亚部分提供了独特的古环境设置，有最长的记录，从格里斯巴赫到Dienerian，微生物增殖后的P-Tr大规模灭绝在世界上。基底三叠纪巨大的海绵微生物的积累，鼓励更全面的研究后生动物微生物礁的发展后，最大的灭绝事件。
Being involved in the organization of IGCP 572 field workshops in Turkey (2009), in Oman (2010), as in the following IGCP 630 field workshops in Kashmir (India, 2014) and in Armenia (2017), I co-wrote for each of them detailed guidebooks and extended reports that can be found and downloaded from ResearchGate website. This paper summarizes the final results obtained by IGCP 572 and 630 members from these four important field workshop sites in the past 10 years, and also attempts to make recommendations for future studies based on these unique localities surrounding the Tethys Ocean. The first field workshop of IGCP 572 was organized in South Turkey in September, 2009, with the logistical support of Dr. Erdal Kosun from the Antalya University. Following the South Turkey field workshop, eight important papers have been published and concerned the well-preserved Permian-Triassic boundary (PTB) microbialites and their ecosystems (including ostracodes, brachiopods, and many of other clades). The 3rd IGCP 572 annual field workshop was held during February, 2010 in the Sultanate of Oman, with Dr. Michaela Bernecker and the deep support from the GuTech University in Muscat. More than 15 papers have derived from the P-Tr successions that IGCP 572 members have investigated during this workshop, including the first study on oceanic acidification based on Boron isotopes. New paleontological studies are still on progress, and concern the Smithian ammonoids, Lower Triassic shark teeth and dental remains as well as basal Triassic conodonts, crinoids and ammonoids. The 1st IGCP 630 annual field workshop was held during November, 2014 in Srinagar, Kashmir, and North India, with the helpful assistance of Prof. Ghulam Bhat from Jammu University. This meeting renewed studies on the classic Guryul Ravine and adjacent P-Tr boundary sections in that region, with new geochemical works on carbon isotopes and pyrite framboids as well as a detailed Induan conodont taxonomy and zonation. Other new paleontological works concern the palynology of the Guryul Ravine Section as some well-preserved organic eukariotic protist (thecamoebians) that cross without damage the PTB. Lilit Sahakyan, Aymon Baud, and Zhong-Qiang Chen organized the 5th IGCP 630 annual conference and field workshop in Armenia on October 8–14, 2017. Several PTB and Lower Triassic sections have been systematically sampled for biogeochemical and geobiological studies. These Armenian sections provide unique paleoenvironmental settings that have the longest record, from Griesbachian to Dienerian, of microbial proliferation following the P-Tr mass extinction in the world. The basal Triassic giant sponge-microbial build-ups are encouraging more comprehensive studies on metazoan-microbial reef developments after the greatest extinction event.
