Analizlerde, t\u00fcnellerin i\u00e7 y\u00fczeylerinde \u00e7evredeki kayalardan farkl\u0131 kimyasal \u00f6zellikler tespit edildi. Bu b\u00f6lgelerin demir, manganez ve nadir toprak elementleri bak\u0131m\u0131ndan d\u00fc\u015f\u00fck; organik karbon, fosfor ve k\u00fck\u00fcrt a\u00e7\u0131s\u0131ndan ise zengin oldu\u011fu kaydedildi.<\/p>\n\n\n\n
