METASOMATİZMA PROBLEMİ

Metasomatizma, mineral ve kayaçların hacim çapında yer değiştirmesinden ibarettir ve bu durum psödomorflar, eski dokuların muhafazası ve duvarlarla (uyuşmayan» çıkıntılı kontaklarla ortaya çıkmaktadır. Ciddi petrograflar, mikroskopik dokuların çeşitli şekillerde açıklanabileceği ve şüpheye düşülen yerlerde doğruyu ortaya çıkarmak için jeolojik ve Jeoşimik düşüncelere baş vurulabileceğini belirtmektedirler. Bu sebeple, jeologlar konunun bütününde yer alamaz, arazi gözlemlerini kabul etmezden önce, cevher gövdelerinin metasomatik orijinleri hipotezlerini kontrol eder.

THE PROBLEM OF METASOMATISM

Metasomatism consists of volume-by-volume replacement of minerals and rocks, as evidenced by pseudomorphs, preservation of older textures, and bulging contacts with walls which do not «match». Serious petrographers admit that microscopic textures may often be explained in different ways, and refer to geological and geochemical considerations for arbitration, where in doubt. Therefore, geologists should not take the part for the whole, but check hypotheses of metasomatic origin of ore-bodies against field observations, before accepting them.
