在过去的二十年里，对火成岩和变质岩石成因的认识都取得了进展。许多关于亚洲（广义）的新研究已经开始在广泛的地质背景下分享新的知识和观点。这期题为“亚洲大洋和大陆造山带的岩石成因和化学成因：最新进展”的岛弧专题，主要介绍东北亚至西南亚的实例，包括三坝川变质带（日本）、大别-苏鲁造山带（中国）、阿曼蛇绿岩和格兰德河裂谷带。这些贡献阐明了与流体活动的作用、高压和超高压岩石中压力-温度-时间路径的调制、带状矿物中保存的逆冲和逆冲/减压路径、地壳和地幔演化过程中矿物的形成和重结晶以及单颗粒矿物和矿物集合体中保存的区域和局部变形的影响有关的有争议的问题。这些问题的提出加深了我们对大陆造山带和大洋造山带地球动力学演化的认识。该专题是在2013年5月在日本千叶幕张展览中心举行的“碰撞、俯冲和变质过程”国际研讨会之后计划的。国际会议的重点是与大洋板块俯冲和大陆碰撞有关的岩浆、交代和变质过程。贡献主要是多学科的，涉及结构地质学、地球物理学、岩石学、地球化学和实验岩石学/矿物物理学，特别是与亚洲的主要造山带有关，以及与世界各地的主要造山带有关。具体专题包括俯冲通道内水合作用和脱水作用之间的联系、大陆和海洋地壳通过地幔的再循环、俯冲/碰撞机制内的变形机制、高压和超高压变质岩的形成和折返以及地球科学中实地数据与实验室实验之间的相互关系。共提交了15份研究报告，并要求在这份特刊上发表。为响应这一呼吁，在提交的论文中选出了五篇文章，在特刊第一部分（本卷）发表。该特刊的其余手稿将作为第二部分在下一卷中出版。该特刊载有来自亚洲和相关地区不同地质地点的原创研究论文。我们相信，这卷提供了一个机会，地球科学家见证最近的进展，大洋和大陆造山背景和地球动力学的解释。
In the last two decades, understanding of both igneous and metamorphic petrogenesis has been progressed. Many new research concerning Asia (sensu lato) has begun to share new knowledge and perspectives in a wide geologic context. This thematic issue of Island Arc entitled ‘Petrogenesis and chemogenesis of oceanic and continental orogens in Asia: Recent progress’, is dedicated to examples from mainly northeast to southwest Asia, including the Sanbagawa metamorphic belt (Japan), the Dabie–Su-Lu orogenic belt (China), Oman ophiolite, and Rio Grande rift zone. The contributions shed light on controversial issues related to the role of fluid activity, modulation of the pressure–temperature–time paths in highand ultrahigh-pressure rocks, the prograde and retrograde/decompression paths preserved in zoned minerals, the formation and recrystallization of minerals during crustal and mantle evolutionary processes, and the impact of regional and local deformation preserved within single grain of minerals and in mineral aggregates. These topics enhance our understanding on the geodynamic evolution of continental and oceanic orogenic belts. The thematic issue was planed after the international symposium ‘Collision, subduction and metamorphic processes’ which was held at Makuhari Messe, Chiba, Japan, in May of 2013. The international session focused on magmatic, metasomatic and metamorphic processes related to the subduction of oceanic slabs and the collision of continents. Contributions were dominantly multi-disciplinary and involved structural geology, geophysics, petrology, geochemistry, and experimental petrology/mineral physics, related to major orogenic belts in Asia, in particular, and those world-wide in general. Specific topics included the linkage between hydration and dehydration within subduction channels, the recycling of continental and oceanic crust through the mantle, deformation mechanisms within subduction/collision regimes, formation and exhumation of high-and ultrahighpressure metamorphic rocks, and the correlation between field data and laboratory experiments in geosciences. In total 15 studies were presented and were called for publication in this special issue. In response to the call, five articles among the presented papers have been selected for publication in Part I (this volume) of the special issue. Remaining manuscripts of the special issue will be published in the forthcoming volume as Part II. The special issue contains original research papers from different geological locations in Asia and related regions. We believe this volume provides an opportunity for the earth scientists to witness the recent progress on oceanic and continental orogenic settings and their geodynamic interpretations.
