Abstract (2. Language): 
Boron » one of the most mobile and least abundant element», lihr average amount of boron to the Ea r th's crust being estimated at less than 10 pa r ts per million. However, it te found in minerals which 'Dccur in nearly all geologic environments. Although boron is «>ne of tt» rarer a id mm unevenly distributed element» in the Earth's crust, there are extraordinary concentrations of toron deposits on an industrial seal« in some localized areas. > r. The known borate deposits of Turkey were dejesited in lacustrine sediments of Tertiary age during periods of volcanic activity wh?ch commenced İn the early Tertiary period and omftnued at least to tue beginning of the Quaternary. All Turkish borate deposit« appear to be aMoclatetİ wMth voloiuitc activity and they have been classified as deposits related to voles nie aettvlty. Although colemanJte, a very common calcium borate, is the predominant mineral in all borate district« apa rt friMn Ktrka, the detaUed mineralogy of the Turkish borate deposits varies considerably. Ot t er principal borate minerals are ulexlte (sodium calcium borate) and borax (sodium borate). Borax occurs only at Kfrka, TertsoMte occurs In the B^a,tUo deposits and pandermite is ateo restofcted appeaiİBg only in the Bigadiç and Sultancayiri deposits. Turkey has mofle recent rapid strides towards rivalling the U.S.A. a» the world*» leading producer oif borates. Boron and borate minerals find extensive uses in today'» modern induaMes,
Abstract (Original Language): 
Doğada az bulunan ve duraysız elementlerden birisi olan bor, yerkabuf unda ortalama 10 ppm'deo ai olarak bilinmektedir. Buna k a r ım bor, her türlü jeolojik ortamlarda olugan minerallerde bulunur. Sor eleış«ıu fnin yerkabuf undaki dağılımı çok az olmasına kargın, belli ortamlardaki bor konsantrasyonunun çok Ifczla orandaki artığı, ekonomik bor yataklarının oluşumunu sonuçlar, Türkiye'nin bilinen borat yatakları, Tersiyer'de bağlayan ve Kuvaterner'ln baflanpcma kadar devam eden volkanik aktivitelerln yer aldığı dönemlerde, Terslyer'in gölsel (laküstrin) ortamlarmda depolaıunıgtır, Türkiye borat yataklarının tümü, volkanik aktlvite ile ilgili yataklar olarak sınıflandırılır. Yaygm bir kalsiyum borat olan kolemanltln, Kırka dışındaki bütün borat yataklarında eg emen mineral olmasına kargın, Türkiye borat yataklarının ayrıntılı mmerolojileri önemli derecelerde farklılıklar göstermektedirler, Ulçksit {sodyum kalsiyum borat) ve boraks (sodyum borat) önemli borat mineralleridir, Be« raks yalnızca Kırka'da gözlenmektedir, Tereit, Bigadiç yataklarında bulunur. Pandermit'e İse yalnızca Biga« diç ve Bultançayırı yataklarında rastlanır, Türkiye, borat üretiminde önder ülke olabilmek amacıyla son yıllarda, ABD ile rekabet etmede büyük adımlar atmıştır. Bor ve borat mineralleri, bugünün modern endüstrisinde geniş kullanım alanları bul. maktadır.
