Abstract

The major target of this research is the classification of pyrite types using fractal and stepwise factor analyses in the Chah Zard ore deposit, Central Iran. The ore occurs within a breccia/vein type and the major ore mineral hosting gold mineralization is pyrite. In this study, data were selected using optical, scanning electron microscopy (SEM) and backscattered electron observations as well as laser ablation-inductively coupled plasma–mass spectrometry (LA-ICP–MS) analysis. Conventional interpretations represent four gold-bearing pyrite types of various textures including fractured and porous Py1, oscillatory-rimmed and simple-zoned Py2, colloform Py3 and inclusion-rich Py4. The stepwise factor process was performed on the centred l

Abstract

The Chargar deposit in the southern part of Tarom metallogenic belt of the Alborz structural zone, NW Iran, shows a volcaniclastic-hosted, low-sulfidation epithermal gold mineralization. The host rocks are part of the Eocene volcanic and volcaniclastic sequence of the Karaj Formation. The main host rock is an andesitic lapilli-lithic tuff. The main ore minerals include chalcopyrite and gold and the gangue minerals are quartz, barite, and calcite. The calculated δ34SH2S values based on sulfide minerals for the Chargar shows a homogeneous signature ranging from −7.6 to −5.6‰, in the Khalifelou deposit range between −5.2 and −1.9‰ and in the Aliabad-Khanchay deposit from −8.1 to −5.5‰. Negative sulfur isotope values and the

Abstract

Stream sediment samples in two sizes of sand and clay/silt from the Chodarchay and Gilankesheh rivers which pass through the Chodarchay copper deposit, northwestern Iran, were measured for their metal concentrations using a sequential extraction procedure. The average concentrations of cadmium (18.22) in sediments from the rivers exceed the world average shale and continental upper crust values. Based on Geo-accumulation Index, cadmium is intensely elevated (in the clay fraction greater than 5 and in the sand fraction between 3 and 5), arsenic and lead are slightly elevated in a few stations and others are not-elevated. The zinc and copper values are almost equal to or lower than Geo-accumulation Index; thus, the sediments are
