摘要
Golbanoo地区侏罗系煤层厚度为5 cm ~ 1 m，下覆薄煤页岩、砂岩和粉砂岩层。利用中子活化分析(INAA)和x射线荧光分析(X-ray fluorescence)分析了煤和非煤岩的地球化学特征。Al2O3、SiO2和Fe2O3是主要的氧化物。戈巴诺煤中微量元素(As、Ag、Br、Sb、Cr、Co、Sr、Zn、Ta和∑REE)的含量高于世界煤。研究区火山活动及其硫化物成矿作用是煤层中微量元素富集的有利因素。
Trace elements geochemistry of the Golbanoo coal basin, Iran
ABSTRACT The Jurassic coal deposit in the Golbanoo area contains coal seams with thickness ranges from 5 cm to 1 m and is underlain and overlain by thin coaly shale, sandstone and siltstone beds. This study reports on the geochemical features of coals and non-coal rocks based on the 30 channel samples were collected and analyzed for trace elements using neutron activation analysis (INAA) and for major elements by X-ray fluorescence. The Al2O3, SiO2 and Fe2O3 concentrations are the main oxides. The amounts of trace elements (As, Ag, Br, Sb, Cr, Co, Sr, Zn, Ta, and ∑REE) in Golbanoo coal are high compared to world types of coal. The volcanic activity and their sulfide mineralization in study area is a favorable factor for accumulation of trace element in coal layers.
