摘要

本研究的主要目的是利用基于溪流沉积物和岩石样本的分段因子分析(SFA)和谱区(S-a)分形模型,在塞姆南省(伊朗中北部)7800平方公里的区域勘探中概述锂异常。通过SFA得出的结果表明,Li位于具有B、Cs、U和Rb的因子F2-4中,该因子用于通过S-a方法计算阈值。利用分形模型对F2-4数据进行了分类,确定了Li异常。F2-4≥1.5的主要异常位于该地区的西南部和北部。此外,李高品位岩石样品与主要的F2-4异常有关。主要异常与Li矿化类型的地质特征相关,表明主要F2-4异常与西南部的火山和凝灰岩单元有关,并与该地区北部的粘土矿物重叠。另一方面,该方法也证明了李成矿的潜力。

Geochemical exploration for Li in regional scale utilizing Staged Factor Analysis (SFA) and Spectrum-Area (S-A) fractal model in north central Iran
The main aim of this study was to outline the lithium anomalies by a regional exploration, at an area of 7800 km2, in Semnan province (north central Iran) using the Staged Factor Analysis (SFA) and Spectrum-Area (S-A) fractal model based on stream sediments and rock samples. Results derived via the SFA denote that Li was located in a factor as F2-4 with B, Cs, U and Rb which was utilized for calculation of the threshold values by the S-A method. The F2-4 data were classified by the fractal model for determination of the Li anomalies. Main anomaly for F2-4≥ 1.5 was situated in the SW and northern parts of this region. Furthermore, Li high grades of rock samples were correlated with main F2-4 anomalies. The main anomalies were correlated with geological particulars of Li mineralization types which represent that the main F2-4 anomalies associate with volcanic and tuff units in the SW part, and overlapped with clay minerals in the northern sector of this region. On the other hand, there are proper potential for Li mineralization which is demonstrated by this method.
