Borates at the Igdekoy-Doganlar locality were deposited in a Miocene lacustrine environment during periods of Paleogene to Early Quaternary volcanic activity. The mineral paragenesis consists of probertite – (NaCaB 5 O 7 (OH) 4 .3H 2 O), ulexite (NaCa[B 5 O 6 (OH) 6 ].5H 2 O), hydroboracite (CaMg[B 3 O 4 (OH) 3 ] 2 .3H 2 O), colemanite (Ca[B 3 O 4 (OH) 3 ].H 2 O), halite, anhydrite, glauberite, smectite and illite. The major element, Ca, is higher in the Igdekoy-Doganlar deposits compared to the averages for andesite and the Earth’s crust. Within the trace elements, notable enrichment is identified in Li, Se, As, Sb, Sr and Cs. Lithium and Se occur in sufficient concentrations to be considered as economically valuable by-products. B and Sr anomalies can be used as an important marker in the exploration for boron deposits. The Y/Ho ratio of the Igdekoy-Doganlar borates is close to chondritic values. The negative Ce anomaly in borates from the Igdekoy-Doganlar deposit suggests that deposition occurred under oxidative conditions. The Eu and Ce anomalies reflect a hydrothermal contribution of REE. Geochemical and geological data suggest that the Igdekoy-Doganlar borate deposits were formed in high-pH playa lakes that were discharged from volcanic and terrestrial environments under evaporative conditions due to the effect of arid-semi arid climate.

埃梅特省 Igdekoy-Doganlar Na-Ca 硼酸盐矿床的地球化学（土耳其安纳托利亚西部）

在古近纪至早第四纪火山活动期间，Igdekoy-Doganlar 地区的硼酸盐沉积在中新世湖相环境中。矿物共生由 Probertite – (NaCaB 5 O 7 (OH) 4 .3H 2 O)、ulexite (NaCa[B 5 O 6 (OH) 6 ].5H 2 O)、氢硼酸盐 (CaMg[B 3 O 4 ( OH) 3 ] 2 .3H 2 O)、硬硼酸钙石（Ca[B 3 O 4 (OH) 3 ].H 2 O）、岩盐、硬石膏、芒硝、蒙脱石和伊利石。与安山岩和地壳的平均值相比，Igdekoy-Doganlar 矿床中的主要元素 Ca 含量更高。在微量元素中，Li、Se、As、Sb、Sr 和 Cs 显着富集。锂和硒的浓度足以被视为具有经济价值的副产品。B、Sr异常可作为硼矿勘探的重要标志。Igdekoy-Doganlar 硼酸盐的 Y/Ho 比值接近球粒陨石值。来自 Igdekoy-Doganlar 矿床的硼酸盐中的负 Ce 异常表明沉积发生在氧化条件下。Eu 和 Ce 异常反映了 REE 的热液贡献。地球化学和地质数据表明，Igdekoy-Doganlar 硼酸盐矿床形成于高pH 湖滩，由于干旱-半干旱气候的影响，这些湖在蒸发条件下从火山和陆地环境中排出。
