第二届国际泥盆纪讨论会于今年八月在加拿大卡尔加里市召开。大会的主要议题是全球古地理再造,其它方面则侧重于生物和物理事件,构造与沉积相、古生物的分区、古气候、海陆变迁、海平面升降、黑色页岩、深水沉积、生物礁、成岩作用与矿产的关系以及全世界与泥盆系有关的矿产资源等方面的研究。会议期间分专题会场开展学术活动,其中以成岩作用与矿产、全球事件及全球古地理再造这两个专题最引人注目。前者与矿产资源直接有关,每次报告的听众达200多人,尤以年青的石油地质工作者占多数,国外在固体矿产的研究中已广泛的开展成岩作用的研究,而且取得了显著的经济效益。后者,表面看 The second International Devonian Symposium was held in August this year in Calgary, Canada. The main topic of the conference is the global re-creation of paleogeography. Others focus on biological and physical events, tectonic and sedimentary facies, paleontology zoning, paleoclimate, land-sea change, sea level rise and fall, black shale, deep water sediments, reefs, diagenesis The role of mineral resources and the relationship between the world and the Devonian-related mineral resources and other aspects of research. During the symposium, academic activities were held in thematic areas, with the two most prominent topics being diagenesis and mineral resources, global events and global paleogeography rebuilding. The former is directly related to mineral resources. Each time there are more than 200 listeners reported, especially young petroleum geologists. In foreign countries, studies on diagenesis have been extensively carried out in the study of solid minerals and significant economic benefits have been achieved benefit. The latter, look on the surface
