The Middle-Lower Yangtze River Valley metallogenic belt is one of the most important metallogenic belts in China, which experienced a long history of mining exploration and utilization. Many geologists have carried out researchs on this area since the 1920s and have published hundreds of scientific papers and more than 50 books. According to statistics, there are 888 scientific papers published in Chinese Journals focusing on the Middle-Lower Yangtze River Valley metallogenic belt from 1959 to 2012, and 185 SCI papers were published from 1990 to 2012. The research about ore deposits and mineralization is nearly occupying half of the total number of the published papers. The amount of published papers about the Tongling ore district in the belt is the highest. The number of published papers about Middle-Lower Yangtze River Valley metallogenic belt formed two peaks in the early 1990s and 2010 -2012 and still exhibit increasing trend, which shows that the Middle-Lower Yangtze River Valley metallogenic belt has been one of the hotspots for geological research in recent years. The researchers focus on four fields: (1) Mesozoic tectonic evolution and dynamic background of magmatism and mineralization, (2) magmatism and plutonic activity, (3) ore-forming system and evolution, (4) metallogenic potential. This edition contains 26 papers generally reflect the latest research progress of the Middle-Lower Yangtze River Valley metallogenic belt and its adjacent areas. Those papers report many new geological and petrological observations, elemental and isotopic geochemical data and high-precision U-Pb zircon age data etc. These documents offer important evidences for further understanding of the origin and evolvement of the Middle-Lower Yangtze River Valley metallogenic belt and also have important significance on prospecting in the area.%长江中下游成矿带是我国重要成矿带之一,矿产资源开发利用历史悠久.自20世纪20年代至今,国内外学者在该地区开展了广泛深入研究工作,取得了丰硕的研究成果,并发表了大量科学研究论文和50余部专著.据统计,1959年～2012年间在公开发行的中文地质学期刊中,有关长江中下游地区的学术论文共888篇；1990年～2012年间公开发表的SCI检索论文中该区有185篇.这些论文中涉及矿床学方面的研究最多,约占论文总数的一半.成矿带内,铜陵矿集区研究程度最高,发表的相关论文数量也最多.有关成矿带的论文发表数量总体趋势逐年增加,在20世纪90年代初和2010～2012年出现两个研究高峰,反映了长江中下游成矿带近年来仍然是我国地质学研究的热点地区之一.近年来,长江中下游成矿带的地质找矿和科学研究均取得了重要进展,地质与矿产研究主要集中在以下几方面:(1)中生代构造转换与成岩成矿的地球动力学背景；(2)岩浆作用与深部过程；(3)成矿系统及其演化；(4)成矿潜力.本专辑收录的26篇论文基本反映了当前长江中下游成矿带及邻区的最新研究进展,所报道的大量地质学新观察、矿床学和岩石学研究、元素和同位素地球化学数据、同位素年代学特别是高精度锆石U-Pb年龄等对深入进一步探讨长江中下游成矿带形成与演化具有重要参考价值,对于推动成矿带基础理论研究和指导找矿勘探均有重要意义.
