Majid Ghaderi, born in 1966 in Tehran, Iran, received B.Sc. and M.Sc. degrees in Geology and Economic Geology from Shahid Beheshti University in Tehran in 1989 and 1992, respectively. He received his Ph.D. degree in Geochemistry and Economic Geology from Research School of Earth Sciences (RSES) of the Australian National University (A.N.U.) in Canberra, Australia in 1998. His thesis was on the sources of Archaean gold mineralization in the Kalgoorlie-Norseman region of Western Australia. Since 2000, he has been an academic member in the Department of Economic Geology at Tarbiat Modares University in Tehran, Iran, teaching graduate courses in Geochemistry and Economic Geology as well as supervising or advising M.Sc. and Ph.D. theses on a number of tungsten, iron, lead-zinc, copper and gold deposits of Iran. His research interests include Economic Geology, as well as Isotope, Trace Element and Exploration Geochemistry. Together with his students and research associates, Prof. Ghaderi has made important contributions to understanding the genesis of magmatic-hydrothermal ore deposits, including those of Cu, Au, the REE, and other critical metals. These contributions have appeared in almost 100 refereed journal articles and in a book on the Porphyry Copper Deposits of Iran. He has been among the founding board of the Iranian Society of Economic Geology (ISEG), a member of the Board of Directors of the Geological Society of Iran and ISEG, and also a member of the Geology Group of the Iranian Academy of Persian Language and Literature and on the Editorial Board of a number of Iranian and international scientific journals.
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
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
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
