| 摘 要： | 土耳其硼酸盐矿床,集中分布在该国西北的西安拉托尼亚地区。重要矿床有比加迪奇、凯斯特莱克、苏丹泽里、埃默特和基尔卡。这些矿床均发育于障壁山间盆地第三纪浅水湖相沉积中,是干旱、半干旱气候条件下非海洋环境的产物。除碳酸盐、硼酸盐等化学沉积之外,山间盆地还广泛接受碎屑沉积,如砾岩、砂岩、粘土、泥岩,以及大量火山碎屑岩、凝灰岩、层凝灰岩等。矿床不同,沉积学特征亦异,但第三纪沉积均具明显的旋回性或韵律性。所有矿床均与火山活动伴生,二者的密切程度超过世界任何硼酸盐矿床。中国辽吉硼矿带的火山沉积变质硼矿床,也许在变质前与前者在矿化上具有共性,只是后者强调了“变质”成矿。

| Abstract: | Turkish borate deceits are confined to Western Anatolia northwest of the country, including five majordepoists: Bigadic, Sultancayin, Kestelek, Emit and Kirka. The deceits are assoicated with Tertiaryshallow-water, lacustrine sediments in closed intermontane basins under conditions of arid climate. The basinswere filled with large amounts of volcanic detrital rocks like tuff, tuffite, etc. in addition to chemicalsediments of Carbote and berate. The depoSits, despite of differences in sedimentary characteristics, all showdear sedimentary rhythm and are related to volcanic activities, closely enough to top any of other deceits inthe world. Volcanic-metagenetic boron depo.sits in Liaoning-Jinn berate province in China were perhapscommon with Turkish deposits in many aspects before metagenesis, but giving emphasis to "ore-formation bymetamorphism,,. |
