The Western Balkan lithium-boron metallogenic zone can be traced for 1500 km, extending subparallel to the Sava-Vardar and Western Vardar zones toward its Turkish counterpart, the Izmir-Ankara-Erzincan zone. Common features are: (1) lithium-boron mineralization is hosted in Lower-Middle Miocene extensional lacustrine basins; (2) lacustrine series consisting of fine-grained siliciclastic sediments and scarce evaporites with intercalations of volcaniclastics, tuff, or travertine indicating syndepositional volcanic activity; (3) lacustrine basins that are usually normal-fault-controlled extensional grabens, with the fault system probably acting as a major fluid pathway; (4) northernmost sodium borate/borosilicate deposits (Jadar, Valjevo, Rekovac; with jadarite, borax, probertite, searlesite) gradually transition to calcium borate deposits southward (Jarandol-Piskanja, Pobrđe; with colemanite ± ulexite); (5) Oligocene/Miocene granitic rocks from the westernmost part of the zone host pegmatite and greisen occurrences with surface lithium anomalies of 0.02–0.08 wt% Li₂O extending for several km²; (6) igneous Li enrichment by fractionation processes is indicated for some younger (?Early/mid-Miocene) peraluminous granite plutons; (7) the formation of the lacustrine basins and associated Li-B mineralization was contemporaneous with the emplacement of the younger phase of Li-bearing granitic intrusions and exhumation of metamorphic core complexes which provided the large-scale heat flow for hydrothermal systems and syngenetic Li-B mineralization.

西巴尔干锂硼成矿区可追溯 1500 公里，与 Sava-Vardar 和西瓦尔达尔区平行延伸至土耳其对应的 Izmir-Ankara-Erzincan 区。共同特征是：（1）锂硼成矿位于下中新统伸展湖盆；(2) 由细粒硅质碎屑沉积物和稀有蒸发岩组成的湖相系列，夹有火山碎屑、凝灰岩或钙华，表明同沉积火山活动；(3) 湖盆通常是正断层控制的伸展地堑，断层系统可能是主要的流体通道；(4) 最北端的硼酸钠/硼硅酸盐矿床（Jadar、Valjevo、Rekovac；含翡翠石、硼砂、磷锰矿、searlesite) 逐渐向南过渡到硼酸钙矿床 (Jarandol-Piskanja, Pobrđe; 有硬硼钙石 ± 钠橄榄石); (5) 带最西端的渐新世/中新世花岗质岩石发育伟晶岩和灰岩，表面锂异常为 0.02-0.08 wt% Li₂ O 延伸数公里²；(6) 一些较年轻的（中新世早/中新世）过铝花岗岩体表明分馏富集火成锂；(7) 湖盆和伴生锂硼矿化的形成与含锂花岗岩侵入体年轻阶段的就位和变质核心杂岩的折返同时发生，为热液系统和同生锂提供了大规模的热流。 -B 矿化。
